An exercise will soon be underway to see how ready the North American electricity industry is to respond to a “major security incident.” A physical attack on hard-to-replace components could result in a widespread, sustained electrical blackout, interrupting water, gasoline and food supplies, experts say. Even a cyber attack could lead to sustained component damage, if, for example, a hijacked SCADA system was told to do what it oughtn’t.

Given the distributed nature of the electric grid, the vulnerabilities are many, accountability diffi cult and authority murky. There are more than 1,900 bulk-power system owners and oper-ators, says NERC, the North American Electric Reliability Corp., a not-for-profi t entity whose mission is to ensure bulk-power reliability.

Two planning conferences have already taken place for GridEx II, the grid-security exercise NERC will run in November. The GridEx II hybrid operational and discussion exercise format will combine a geographically distributed operator environment and a tabletop exercise for execu-tive leadership. For one and a half days, players will receive sequenced email messages detailing plausible scenarios. For example, a substation break-in turns out not to be for purposes of stealing copper. Instead, the intruder uploads a virus onto the network from a USB drive.

Players will engage in both internal response measures and external information sharing activi-ties. A control cell in Washington, D.C., will coor-dinate.

Organizations can be “full players” or “moni-tor/respond players” engaged in a more passive, less resource intensive manner. The original goal was to have utilities, regional entities and oth-ers to a total of 100 participants, but registration is already near 150. Deadline for registration is Nov. 1 with the exercise conducted the 13th and 14th. There will not be in-depth technical discussions on fi rewall settings or other sensitive information.

A recent article in the New York Times says the U.S. electricity grid is mostly controlled by the investor-owned companies or municipal or regional agencies. The Edison Electric Institute, the trade association of investor-owned utilities, told the newspaper that it has the expertise to run 5,800 major power plants and 450,000 miles of high-voltage transmission lines.

The article further points out that many utili-ties use such “antique computer protocols” that they are safe from hacking. This is called “secu-rity through obscurity.” Others, it goes on to say, rely on Windows-based control systems common to many industries and are of continu-ing concern. There’s an irony here, and for all its benefi ts, you would have to say that Microsoft’s success on industrial plant fl oors has been a mixed blessing.

The Best Engineered Water Filtering

Solution Always Costs Less

Why Should You

Filter Your Water?



Nippon Atomized Metal Powders Corp. uses a patented water-jet atom-ization process to make high-quality super-fi ne metal powders that are of consistent composition and particle size from copper, bronze, brass, silver, gold and stainless steel.

Applications for the metal powders include electronic components and assemblies, bearings, cutting and polishing tools, jewelry and metal injec-tion molding.

To get there, Nippon Atomized refi ned the process of water jet atomi-zation to produce metal powders with well-shaped, uniform particles in the range 1.5–500 microns.

Following the water atomization stage, the resulting metal powders are dried, screened and blended. A key aspect of the blending operation — and one involving one of the few non-Japanese equipment items in the factory — is a 700-THCX-90-SS rotary batch mixer supplied by Munson Machinery Co., Utica, N.Y.

Koji Yamamoto is general manager of the R&D division of Nippon Atomized and heads one of the fi rm’s two production divisions. He says the mixer blends large batches with short cycle times. Discharge is com-plete, and most importantly, Yamamoto says, the mixer is effective at avoiding particle size segregation on discharge.

A tradition in metal powdersNippon Atomized Metal Powders was established in 1964 in the city of

Noda, which is around 20 miles north of Tokyo and perhaps best known as the home of Kikkoman soy sauce. In 2012, Nippon Atomized built a new site in a neighboring prefecture to make super-fi ne metal powders by the water jet atomization process. Today the company employs around 100 people and has an annual output of about 2,400 tons, of which one-third is exported. Powdered metal products include:

• Copper, silver and gold powders for conductive pastes used in electronics• Bronze powders for bonding industrial diamonds in cutting tools• Bronze and brass powders for bearings in electric motors and car

parts

• Silver and gold powders for metal clay, a craft material developed in Japan

• Soft magnetic alloy powders for inductors used in electronic power supplies

• Small amounts of stainless steel powders for metal injection molding

Atomization in the making of metal powders can involve gas or water jets, centrifugal sprays, mechanical milling and electrolysis. Water-jet atomization technology was invented by a Japanese research institution

and licensed and then improved upon by Nippon Atomized Metal Powders.

In water atomization, Yamamoto explains, water pumped at high pressure through a ring-shaped nozzle creates a convergent conical jet. Molten metal fed into the center of the cone is blasted into ine droplets, which solidify into powder as they fall into a tank of water beneath the nozzle.

Compared to other methods, water jet atomiza-tion is economical and lexible, Yamamoto says. It allows tight control over density, shape and diam-eter — from microns to millimeters — and works with many different metals and alloys.

A drawback of the original water atomization process is that the particles could have poor shape and ineness compared to those made by gas atomization. Nippon Atomized’s higher-pres-sure process produces super-ine powder with spherical particles down to 1.5 microns.

In use of a water jet, critical variables include the aspect angle, water pressure and low rate. Temperatures of the molten metal, water and surrounding atmosphere are also important. Finally, downstream operations such as drying and blending of the powders must be done cor-rectly to maintain powder quality.

Scrap into valuable productsRaw materials enter the site in various forms,

many of them having been recycled. The copper, for instance, is a mixture of electrolytically reined virgin metal and scrap from electric cables and the electronics manufacturing industry. Stainless steel arrives as scrap. Other raw materials include high-purity tin, gold and silver.

Metals are melted in an induction furnace. As the melt forms, the furnace operator uses a spectrograph to adjust and control the resulting alloy compositions.

Downstream of the furnace is the water atomization machine, followed by equipment to dewater and dry the metal powder. Powders pass through a gyratory box screener to control particle size. For the inest powders, ultrasonic sieving and an air classiier carry out the same task. Finally, the powders are homogenized and blended, sieved again and packed into drums for shipping.

Material rejected at various points in the pro-cess is returned to the appropriate stage: re-siev-ing, re-mixing, atomization or re-melting. A small fraction ends up as waste that is sold to mining companies or scrap merchants.

Combines capacity with performanceThe Munson rotary batch mixer plays a key role

in producing metal powders having particle sizes from 10 micron up to 500 micron (30 mesh) and specifi c gravities in the range 1.8–3.5. The mixer’s volume is 90 cu ft, and typical batch sizes are 8,800–11,000 lbs.

“We use the mixer mainly as a homogenizer to avoid material segregation,” Yamamoto says. “We need to be sure that particle size distribution is the same across the batch, and from one batch to the next. With the Munson, we get good blending and complete discharge without segregation, and short mixing time, even with the large capacity.”

Nippon Atomized purchased the mixer to increase capacity. “Our previous double-cone blender was limited to 1,500 kg per charge,” Yamamoto says, “and a batch took 20 minutes to blend. This was too small and too slow for our production needs. The rotary batch mixer blends up to 5,000 kg in just 5–7 minutes.”

The unit’s four-way mixing action — tumble, turn, cut and fold — achieves batch uniformity rapidly, and more gently than with agitated blend-ers. Continuous rotation keeps material in motion

at all times, preventing particle-size segregation during discharge.

Why the company importedYamamoto says Nippon Atomized imported a

mixer because, “We wanted complete discharge without segregation, plus large capacity. There are no Japanese mixers that combine these impor-tant features. I believe one domestic machinery producer makes a similar rotary batch mixer. However, that mixer has a complex construction and I believe it would to be hard to use. It was also comparatively expensive.”

The Japanese powder metallurgy industry mostly uses V-blenders and double-cone blenders, Yamamoto explains. These mixer types provide com-plete discharge, but there tends to be segregation of particle sizes: “In general, the particle size distri-bution moves from fi ne to coarse as the mixer is dis-charged. The Munson mixer avoids this problem.”

Headroom is tight at the Nippon Atomized facil-ity, Yamamoto says, and it was a challenge to fi t the Munson mixer into the available space, as it is loaded from an overhead container moved into position by a crane. Customer acceptance was

12 Mills, Granulators & Crushersalso an issue, and even now some are reluctant to change to the offshore mixer for their products.

But any initial headaches were well worthwhile, Yamamoto says, with the mixer proving both effective and reliable after nearly three years in operation. When a change of grade is required, cleaning is straightforward; a small quan-tity of the new product is used to clean the mixer and is then recycled.

“We don’t have to worry about maintenance,” Yamamoto says. “With our previous mixer, the axle and drive chain caused a lot of trouble. Here, as long as the drum alignment is okay, the rotary batch mixer is trouble-free, and the quality of blending means lower costs for quality control.”

The next step, Yamamoto concludes, is “to replace our other old mixers with Munson machines.”

For many dry foodstuffs the ingress of even small quantities of water can compromise product performance. Granular foods — such as instant coffee, sugars and gravy granules — can all change, with the uptake of water, from relatively free-fl owing, easily manageable powders to a far less desirable clumped or even solid mass.

Likewise, in manufacture, inadequately controlled moisture levels can compromise process-stream fl ow characteristics and other properties, leading to blockages, stoppages and reduced effi ciency.

Knowing when — and to what extent — to control moisture depends in the fi rst instance on understanding how a powder responds to humid-ity. Recently completed experimental work addresses the question and includes data for mannitol, sorbitol, fl our and microcrystalline cellulose (MCC) that illustrate the breadth of behavior exhibited.

Results also show how dynamic, shear and bulk-powder characteriza-tion, in combination, provide the understanding needed to effectively manage humidity’s potential impact.

Humidity and the resultant uptake of moisture can have a transforma-tive, often unpredictable, effect on powder behavior and processing effi -ciency because of its infl uence on a broad range of behaviors, including fl owability and compressibility. In particular, storing powders at unsuitable humidity levels is the primary cause of caking, adverse not only to pro-cessing, but also end-use performance and product value.

Food-powder processors must understand the extent to which a pow-der will take up moisture and, crucially, how this affects processing charac-teristics in various production environments. Managers are then in a posi-tion to assess what, if any, moisture control strategies are required.

Focus on powder fl owPowder-fl ow properties are some of the most important when it comes

to processing behavior, infl uencing movement but also defi ning per-

formance in important unit operations such as blending, die-fi lling and fl uidization. Powder fl owability depends on many variables. Multiple mechanisms contribute to overall behavior. That’s why predicting fl ow performance, and by extension humidity’s impact, is challenging. Most important — and this might seem counterintuitive — these diverse effects mean that certain moisture levels may in practice be benefi cial to powder processing, a fi nding often overlooked.

Powder behavior, including its unique fl owability characteristics, is defi ned by parameters relating to both “environmental” variables, such as humidity and air content, and the constituent particle’s physical attributes.

Multi-facet characterization quantifies humidity’s impact on food powdersWhat you need to know when developing a moisture-control strategy

By Dr. Katrina Brockbank and Jamie Clayton

Flow depends on how easily particles can move relative to one another. Flow is affected by mech-anisms such as: friction; mechanical interlocking; electrostatic interaction; and cohesion. The rela-tive magnitude and impact of these competing mechanisms is speciic to each individual powder, leading to widely diverse behaviors.

To illustrate this point consider lour (see igure 1). Tests show that as moisture content increases there is an initial increase in Basic Flowability Energy (BFE), a dynamic property that quanti-ies the ease with which a powder will move, as might be expected. This can be attributed to liq-uid bridging, a mechanism often responsible for moisture’s detrimental impact on low behavior. When a liquid bridges the gap between particles it increases the adhesive forces between them and inhibits particle motion. However, beyond a certain concentration, BFE starts to decrease. Moisture lubricates the particles, reducing inter-particulate forces and increasing lowability.

Conversely, powders such as microcrystalline cellulose (MCC), a food additive widely used as a thickener, exhibit electrostatic charge between particles at low humidity. For MCC, increas-ing moisture levels initially decreases BFE, as

moisture has an earthing effect on the charge, grounding the sample and reducing inter-particu-late forces. Here, liquid bridging begins to domi-nate at a higher humidity percentage, above 50% RH, at which point BFE begins to increase once more.

This simple example illustrates how moisture affects just one of the dynamic powder proper-ties used to quantify low behavior. However, water’s effect cannot be described using a single value. Instead, a holistic approach generates a range of properties directly related to process performance. Multi-faceted powder characteriza-tion delivers comprehensive insight into powder behavior.

Multi-faceted powder characterizationTraditionally, powder characterization relies

on bulk-property measurements for information on density, permeability and compressibility and shear testing, which deines behavior as moder-ate to high shear. Shear analysis was developed in the 1960s to support hopper-design methodol-ogy and is useful for characterizing consolidated powders and their transition from a static state into a dynamic regime. More recently, however,

20 Food Industrypowder processors are turning to dynamic powder measurement for fur-ther insight into powder behavior, most especially how powders fl ow and perform in low-stress and aerated environments.

Dynamic characterization measures the torque and axial force acting on a rotating blade as it passes through a powder sample. This generates fl ow-energy values that directly correlate with in-process powder behavior. With dynamic measurements it is possible to simulate and directly test the effects of various operating environments by, for example, measuring the properties of the powder in the consolidated, conditioned, aerated or even fl uidized state.

Such testing produces dynamic parameters such as BFE, Specifi c Energy (SE) and Aerated Energy (AE) that directly correlate to in-process behav-ior to support a transition from traditional “trial and error” operation to a more knowledge-led approach. Measuring dynamic characteristics allows precise and reliable quantifi cation of powder properties and provides data that can be used to increase effi ciency.

BFE is the baseline dynamic measure and indicates as to how the powder will fl ow under forcing conditions, such as in feeders or extruders. It is mea-sured as the instrument blade rotates downwards through the conditioned sample, forcing the powder against the base of the test vessel. Conversely, SE is measured as the blade traverses upward through an unconfi ned sample and

22 Food Industryindicates how powder fl ows in the absence of applied stress. Such may occur on the process line when, for example, a powder is being poured from one location to another.

AE methodology is identical to that for BFE except that measurements are made as air is pumped up through the sample at a controlled velocity. This provides a direct measure of the powder’s response to air, extremely valuable for fl uidization and pneumatic conveying applications. More gen-erally it also yields one of the most sensitive measures of the strength of cohesive bonds between particles.

The Freeman Technology FT4 Powder Rheometer is a universal powder tester that measures dynamic, bulk and shear powder properties. This enables multi-faceted testing and gives the user the ability to systemati-cally test, for example, the effect of changing humidity levels on relevant powder properties. How all three sets of properties vary as a function of moisture uptake provides important insight into what humidity level is best suited to all elements of the production process and the necessity or oth-erwise of control. Such testing therefore directly supports process optimi-zation and the appropriate application of drying strategies.

Humidity’s impact on mannitol and sorbitolThe unpredictable effect of moisture on food ingredients is well illus-

trated by comparing the effects of changing humidity on the artifi cial sweeteners mannitol and sorbitol. In an experimental study, the dynamic, shear and bulk powder properties of these powders were measured using a powder rheometer to fully capture humidity’s impact on both materials. Mannitol and sorbitol fi nd widespread medical and commercial application as sugar substitutes. Despite their identical chemical formula — they are isomers of the same compound — the results show that they display quite distinct and contrary responses to moisture.

When moisture is introduced to hydrophobic mannitol it acts as an intra-particular lubricant, reducing BFE. As illustrated in Figure 3 this downward trend continues until around 50-60% relative humidity. At this point liquid bridging is established, leading to more inhibited fl owability and a rapid increase in BFE.

Sorbitol on the other hand, has the converse response, exhibiting an increase in BFE at low RH percentages, followed by a decrease of around 30% to 40%. Sorbitol initially adsorbs water at the surface, creating strong liquid/

Figure 4: Measurements of permeability, percentage change in pressure drop, as a function of humidity show that mannitol undergoes a signifi cant change in per-meability while sorbitol remains relatively unaffected by the presence of moisture.

Figure 5: Shear test data show different trends in behavior for mannitol and sorbi-tol, relative to dynamic characterisation, suggesting that the process environment might be extremely important in determining the impact of humidity.

solution bridges between particles. Beyond 40% RH, however, the material’s high solubility means that any additional moisture will have a lubricating effect, eventually reducing the sample to a “wet mass” phase that at high humidity takes on a slur-ried form.

This contrast in response is also evident when the powders are subject to permeability testing. Here the mannitol shows a large change in permeability as RH is increased from the baseline state to around 30 – 40%. The pressure drop across the sample test bed increases sharply, indicating a signifi -cant reduction in permeability. However, beyond this point, pressure drop falls back to the baseline condition, and then lower, showing that permeability steadily increas-es at higher levels of RH.

Sorbitol, in contrast, exhibits a rela-tively consistent permeability as humidity increases, with only modest changes in measured pressure drop.

These responses can once again be related to the relative hygroscopicity of the powders, with the hydrophobic mannitol experiencing signifi cantly greater variation in permeability than the hydrophilic sorbitol. Above an RH of between 60% – 65% both systems will experience surface saturation and their relative permeability performance then become increasing similar.

Additional observationsShear testing was also undertaken for

both powders. For many materials, shear data are less sensitive to the impact of any changes induced by humidity — as shown in Figure 5 by the results for mannitol. Sorbitol, however, shows quite extreme behavior at higher levels of humidity and, in contrast to the trends observed during dynamic and permeability testing, shows a steady increase in shear stress, suggesting poorer fl ow properties as humidity increases.

These results illustrate how the pro-cessing environment can have a strong infl uence on the behavior exhibited by sorbitol, shear data being more indica-tive of performance under moderate to high shear conditions, such as in a hop-per, while dynamic parameters and per-meability more closely refl ect in-process behavior across a more diverse range of unit operations. This underlines the importance of measuring powders using different techniques and, most especial-ly, interpreting results within the context of how the powders will be processed and used.

To fully optimize powder process-ing it is essential to comprehensively characterize powders using a variety of techniques. This enables not only precise measurement of the effects of humidity

but also simulation of the conditions to which the powders will be subjected.

No life form, whether human, animal or plant, survives without water. The same is true for industry, regardless if it’s mining, food & beverage processing or steel making.

For one, water facilitates and optimizes production, whether by means of cooling equipment, cleaning totes, barrels or storage tanks. Used in these ways, clean water quickly becomes wastewater, full of impurities. Given increasing regulatory vigilance regarding wastewater handling, that water must be disposed of or recycled in the most environmentally friend-ly manner possible.

Aiding wastewater disposal or recycling is a wide range of acids used in its processing that makes it safe to either reuse or introduce to the envi-ronment. Diaphragm-type metering pumps successfully meet the chal-lenges inherent in most wastewater-handling applications that require the use of any of a wide array of acids.

The challengeAcids are an industrial jack-of-all-trades for a dizzying array of applica-

tions and processes, including making agricultural fertilizers, cosmetics production, drinking-water fl uoridation, pH adjustment in cooling towers and boiler-water pretreatment. Versatility makes acids a critical compo-nent in water and wastewater handling.

Some common acids used and their characteristics include the follow-ing:

Hydrofl uosilicic acid: Occasionally referred to as “silly” acid, hydrofl uosi-licic acid is often used in drinking-water fl uoridation, as a wood preserva-tive agent and in ceramics production. Hydrofl uosilicic acid is corrosive to most metals, and has a tendency to fi nd leak paths.

Hydrochloric acid: Also known as muriatic acid, it is used to remove scale from boilers, in chemical cleaning and to regenerate water used in treating deionization units.

Phosphoric acid: Used in metals processing, as an etching agent in semiconductor processing and as a biological-growth nutrient.

Sulfuric acid: Commonly used for pH adjustment in water treatment, making car batteries and metal pickling, cleansing and plating. Because sulfuric acid is highly exothermic, it is one of the more challenging acids to pump.

Citric acid: A rather weak acid, it is used as a preservative and fl avoring agent in food and beverage processing, and as an ingredient in making cosmetics, pharmaceuticals and household cleaning products.

Safety in containing, controlling and handling these acids is a critical

concern, not only to protect worker health and productivity, but to ensure zero environmental impact.

Some acids are more aggressive than others and their corrosive nature

and temperature can change dramatically at different concentrations or when diluted. Sulfuric acid, for example, becomes more corrosive when diluted and has a high specifi c gravity relative to water, so slower pump stroke speeds are desirable when handling it.

Given their aggressive nature and the need to accurately control dosage rate to avoid overfeeding, acids need to be fed via a metering pump with a high level of repetitive accuracy, generally +/-1%.

The material that the pump is constructed of also requires thoughtful consideration. While C-20, PVDF and PVC are the most commonly used housing materials in acid-metering pumps, care must also be taken that all wetted components are compatible with the specifi c acid being handled. No one single material works well with all acids. Choosing the wrong materials of construction can lead to, at the least, pump failures and, at worst, harmful acid leaks.

The solutionSome experts say hydraulic, mechanical or electronic diaphragm meter-

ing pump technology is the best choice for acid injection in wastewater handling. In fact, the Neptune Chemical Co., North Wales, Pa., says its 500 Series hydraulic diaphragm metering pumps, 7000 Series mechani-cal diaphragm metering pumps and PZ Series electronic solenoid-driven metering pumps help set the standard in safe, effi cient, reliable acid-han-dling in wastewater applications.

Neptune’s 500 Series hydraulic metering pumps inject a precise and controlled chemical amount; feature an internal relief valve; have leak-free operation; can handle higher pumping pressures; require minimal main-tenance; can be constructed with an automatic stroke control actuator or variable-speed motor; have low energy usage; and feature an easily adjustable micrometer dial that can be adjusted whether the pump is run-ning or stopped.

Hydraulic metering pumps operate in the harshest product-handling conditions and last for up to 20 years of service. Hydraulic diaphragm pumps have a fl ow-rate deviation of less than 1%. The 500 Series pumps feature a 10-turn micrometer dial that can be calibrated to 1% incre-ments from 10% to 100% of fl ow capacity. The pump’s stroke mechanism moves only when adjusted, eliminating unnecessary wear, while the pis-ton is powered through the complete stroke length at all capacities. This

removes any concerns about excessive stress, wear or shock.

The 500 Series pumps also feature a “variable oil by-pass stroke adjustment option” that delivers better valve perfor-mance than metering pumps with variable-linkage designs. The valve checks optimize per-formance because they have extra time to seat since they are idle during the by-pass portion of the suction and discharge strokes. The pump valves have cartridges that are removed for cleaning without disturbing the pump’s piping, and referred to as “EZE-CLEAN” valves by Neptune.

To quell material-compati-bility concerns, the hydraulic metering pump body, valve and seat construction materials include 316 stainless, C-20, PVC and Kynar. Valve checks are available in 316 stainless steel, C-20, glass or ceramic. The 500 Series pumps can produce up to 94 gallons per hour of fl ow at 100 pounds of pressure (60 gph/227 lph if the pump is duplexed). Operating temperatures range from 125 F to 200 F with maximum pressures from 150 to 3,000 psi.

Mechanical mattersNeptune 7000 Series diaphragm metering pumps are mechanically actu-

ated and handle clear liquids with viscosities ranging from water-like to 5,000 cPs — ideal for municipal water and wastewater treatment applications. No contour plates are used on the liquid side of the diaphragm. A straight-through valve and head confi guration delivers improved fl ow characteristics.

Pump capacity is manually adjustable via micrometer dial while the pump is running. This allows the pump to produce fl ow rates ranging

from 10 gph to 450 gph at head pressures up to 150 psi. Liquid ends are constructed of PVC with explosion-proof, variable-frequency drive and wash-down duty motor options available. The pumps are self-priming and provide superior performance moving chemicals containing small impuri-ties, such as sulfuric acid.

When choosing between a hydraulic or mechanical diaphragm metering pump, take into account the specifi c needs of the operation.

The hydraulic pump has a PTFE disc that fl exes between two perforated plates. Because the diaphragm is hydraulically balanced, the pump can operate against higher discharge pressures than a mechanical diaphragm pump. On the other hand, a hydraulic diaphragm pump doesn’t have the same suction-lift capabilities as a mechanical diaphragm pump. Hydraulic diaphragm pumps, such as the 500 Series, do offer built-in relief protec-tion, especially desirable in high-pressure applications.

Finally, electronic metering pumps are a viable option in acid-handling

How it works:

Fluid enters the pressure vessel tangentially at high velocity. A centrifugal action is created, which forces the solids to sepa-rate and enter the sump, while the clean liquid exits up through the standpipe. The solids collect in the sump, and can easily be purged. The operation is so simple, it can be set to automatically purge on a timed interval.

operations. Stroke length and speed adjustments make them particularly suited for low-fl ow acid-feed applications, which can require a wide turn-down capability.

Neptune PZ Series pumps feature a “pulse” metering design that oper-ates on any single-phase voltage from 94 VAC to 264 VAC — a crucial consideration if the pump will be operating on solar-powered batteries. Manual stroke-length adjustment ranges from 50% to 100% with propor-tional control, cycle and counter functions built-in. The PZ Series is avail-able with a PVDF pump head suitable for handling most acids.

Other considerationsIn addition to the pumps, when feeding acids, ancillary piping and

accessory components must be carefully considered and selected.When practical, acid-feed skids should be constructed of corrosion-resis-

tant structural FRP or polypropylene. If metallic skids are required, they should include an appropriate paint coating that will resist the specifi c acid that is to be handled. Integral or secondary containment is also usu-ally desirable.

Diaphragm metering pump check valves operate best when the acid being pumped is clean and free of particulates, so the suction piping

system should always include an appro-priately sized strainer. When pumping concentrated sulfuric acid, a sludge trap is desirable for removing sludge particles, which will help minimize the possibility of pump failure.

Calibration columns provide an inex-pensive, yet reliable and accurate means of verifying pump fl ow rate. A calibration column of clear PVC is suitable for many acids, although borosilicate glass columns are available and required for use with some acids. A notable exception is hydro-fl uosilicic acid, which will etch glass.

An injection quill or corporation stop injects the acid into the center of the pipeline, tank or process for more rapid and uniform chemical dispersion. This helps to protect the pipe or tank walls from the corrosive effects of the acid.

Final words As mentioned, water is critical to all

forms of life and the successful opera-tion of a wide range of industries. Safe, clean and responsible water treatment, conservation and disposal are increasingly critical issues. Acids in many forms play a correspondingly critical role in treating water and wastewater. Like water itself, proper care and handling of acids must be observed. While wastewater-treatment facilities are aware of their responsibilities in ensuring safe water sources, they must also operate as cost-effectively as pos-sible. That’s where effi cient and reliable pumping technology enters the picture.

I was pleased to read a recent report from the American Chemistry Council (ACC) having a very optimistic eco-nomic outlook for the Chemical Processing Industries (CPI) through the year 2020 due to investments linked to low-cost shale gas. According to the report, nearly 100 new shale gas-related projects valued at $71.7 billion in capital

spending have been announced by chemical companies worldwide. This will result in signifi cant investment in capital equipment and create more than 500,000 new jobs.

Tiitled “Shale Gas, Competiveness, and New U.S. Chemical Industry Investment: An Analysis Based on Announced Projects,” the report is based on a detailed examination of the 97 chemical industry projects that have been announced as of March, 2013. It explains that the $71.7 billion in capacity expansion will engender an additional $66.8 billion in chemical industry output, a 9% gain above what otherwise would have been the output in 2020.

The big news for processing professionals is that nearly $30 billion of the $66.8 billion in expenditures will go towards purchasing processing-related equipment. Approximately 26% of the nearly $67 billion will be allocated for such major process equipment as pumps, pressure vessels, heat exchangers, compressors, etc. Another 8% will be spent on process instrumentation, 5% on valves and piping and 4% on electrical equipment.

Peak in 2015The report forecasts that $12 billion of the $68.8 billion will be spent in

2014 and peak at $15 billion in 2015. This means that CPI professionals attending the 2013 CHEM SHOW in New York this December will be able to see and source a vast array of the innovative equipment and technol-ogy they will need to meet this increased production demand over the next two years. More than 300 process equipment manufacturers from around the world will be showcasing solutions process professionals won’t be able to see anywhere else.

In addition, the AIChE Northeast Manufacturing Conference at the

CHEM SHOW will feature leading industry experts presenting valuable insights and information specifi cally geared toward engineers working in the chemicals, pharmaceuticals, food and other process industries.

And the good news just keeps getting better. The report predicts the 97 projects will create 46,000 jobs in the chemical industry, another 264,000 in supplier industries like ours, and 226,000 more jobs in local communities where spending by the new chemical-related workers live. In addition, the work on these projects could lead to 1.2 million tempo-rary jobs through 2020, including several thousand in process equipment manufacturing.

An industry magnet“The United States has become a magnet for chemical industry invest-

ment, a testament to the favorable environment created by America’s shale gas as well as a vote of confi dence in a bright natural gas outlook for decades to come,” notes ACC president and CEO Cal Dooley. The large number of foreign chemical fi rms investing in the U.S. is unprec-edented in recent history and underscores that nowhere else in the world is the outlook as bright when it comes to natural gas, says the report.

The report further predicts that the buildup should continue well beyond 2020. ACC estimates that an additional $24.5 - $29.5 billion in chemical industry investment could occur between 2020 and 2025.

This is great news for the CHEM SHOW, as our mission for nearly 100 years has been to serve as the best resource for process equipment and solutions. To learn more about attending or exhibiting at the 2013 CHEM SHOW, please visit our website www.chemshow.com.

Monitoring a control valve’s position in process industries is typically done using conventional cabled position switches meant for normal manu-facturing environments. These include electromechanical limit switches, proximity sensors, magnetic switches and photoelectric sensors.

While these devices address the functional requirements for sensing “open/closed” valve positions, inherent design characteristics may limit their life expectancy or make them unsuitable for use in potentially explo-sive gas/dust environments.

For such cases, there are position switches and sensors designed expressly for demanding conditions. Their application is described in two examples below.

Besides the two examples discussed, wireless contact (e.g. electrome-chanical limit switches) and non-contact (e.g. magnetic sensors, inductive proximity sensors, photoelectric sensors) are used for position monitoring and control in many process-related applications, including:

• Monitoring doors/windows in grain silos• Position monitoring of marine loading arms• Material handling/conveyor systems• Printing processes• Wood processing systems• Chemical processing and packaging• Position monitoring of fi re protection fl aps

Monitoring valve positionIn the fi rst example, derived from a natural gas pumping station, the

notion was that the open and closed positions of the manually operated valves be detected and that appropriate control signals be sent to a con-trol center.

To achieve this, two wireless electromechanical limit switches were fi xed to the valve head.

By design, these ATEX-IECEx-rated position switches operate at an extremely low voltage and current level, and well below any power level capable of producing a spark. Each features an electro-dynamic energy generator, precluding the need for a battery or external power source.

The energy generator converts the mechanical displacement of the actuating arm to electrical energy using the movement of a coil through a magnetic fi eld. This “energy harvesting” mechanism generates suffi cient electrical power to send a wireless, encoded control signal to a wireless receiver mounted outside the hazardous zone.

Going wireless streamlines position monitoring in explosive environmentsSwitches operate at extremely low voltage and current; feature an electro-dynamic

energy generator



By Peter Engstrom

In one example, achieving wireless valve position monitoring involved limit switches actuated by a “fl ag/cam” mounted to the valve head

Filler pipe positioningSimilar wireless switches proved of value in a reinery’s tank truck illing

facility. Here the goal was to ensure that the neck of the fuel illing pipe was properly positioned above the opening in the tank truck being load-

ed. Wireless switches were also used at a tank truck illing station, ensur-ing illing pipe necks are properly positioned.

Sensing of this alignment was initially accomplished using a “hard-wired” limit switch actuated by a mechanical lever. A steel wire acted as a “mechanical limit” such that the hand lever could only be operated when the ill neck was in position above the tank truck’s ill opening.

While this solution was functional, the electrical cables from the switches to the control panel quickly wore and could be

damaged by the frequent movement and chaing by the fuel pipe. Replacing the “cabled” switches with wireless functional-equivalents eliminated the problem, result-ing in a reliable, robust long-term solution.

In both of the examples discussed, the users beneited from the reduced mainte-

nance required, especially given there are no batteries or cables to replace. With no cables to run to the control cabinet instal-lation costs were reduced. The cost of Ex-Rated cables and connectors was elimi-nated.

The use of “radioed” signals allowed the control cabinets to be located outside the explosion-risk area and safe operation was realized in Zone 1 and Zone 2 explosion-risk areas.

Investments in the infrastructure industries in many parts of the world are spurring demand for high power AC drives, according to new analysis by ARC Advisory Group.

Overall, the cement & glass, electric power, oil & gas, and mining indus-tries had good growth in 2012. Most of this growth was in the emerging economies in Asia. In spite of this regional growth, slowdown in Europe,

investment cut-backs in Latin America, and a signifi cant slowdown in Japan resulted in a slight decline of the worldwide high power AC drives market, the report states.

The report, titled “High Power AC Drives Global Market Research Study,” found that suppliers are in a good position regardless of the cur-rent and future economic uncertainties because high power AC drives are a key product for improving energy effi ciency in the industrial arena. “Demand for high power AC drives will continue in emerging markets because investments in the manufacturing, infrastructure and building automation sectors must continue for economic development,” said Senior Analyst Himanshu Shah, the report’s principal author.

Water & wastewater facilities, airport facilities and power plants will increase their direct use of high power AC drives, as well as support-ing industries such as metals & mining, cement & glass and chemical. Developing economies continue to need improvements in their infrastruc-ture. Also, in most developed countries, the infrastructures are crumbling in many industries. Modernization of these infrastructures will create addition-al demand for high power AC drives, today and throughout the forecast period of the worldwide outlook.

World energy consumption is expected to rise dramatically in the next few decades. Demand for and costs of energy will only increase with future population growth and increased industrialization. Environmental and sus-tainability concerns will make it imperative that national governments and private industries respond effectively and responsibly to the future energy challenges to cooperatively develop competitive energy policies that ensure affordable and reliable energy supplies.

In developing countries, demand is increasing for new power generat-ing plants that utilize high power AC drives in many applications, such as turbines and compressors. Meanwhile, environmental concerns have raised interest in renewable sources of energy. High power AC drives are used for controlling traditional and renewable power generating processes. Additionally, initiatives to save energy at various levels, ranging from local to national governments, industrial operations to consumer awareness, fuel growth for the use of high power AC drives and to reduce the growth rate of worldwide energy consumption, according to the study.

In addition to the quantitative assess-ment of the high power AC drives mar-ket, this ARC study provides an insightful analysis of the products and strategies of the leading high power AC drives suppliers and explores issues that will impact these businesses well into the future.

Global toxic and combustible gas detec-

tor market predicted to growThe worldwide market for toxic and

combustible gas detectors will continue to grow next year, according to a new ARC Advisory Group study.

The threat that toxic and combustible gases pose to the safety of plant person-nel and nearby communities has drawn greater attention in recent years. Several catastrophic accidents, such as the Pike River mine explosion in New Zealand, have given industrial safety more prominence in the public consciousness and spurred demand for both safety systems and safety instrumentation like toxic and combustible gas detectors. Compliance with increas-ingly tough safety regulations will remain a major factor driving investment in safety systems and toxic gas detectors among oil

& gas, reining, petrochemical and mining customers, according to ARC.“Protection of human lives and plant assets is critical to all organizations

and that is why, even though the economic recovery has slowed down in recent years, we still expect the gas detection market to grow,” accord-ing to ARC Analyst Inderpreet Shoker ([email protected]), the principal author of ARC’s “Toxic and Combustible Gas Detector Global Market Research Study.”

The toxic and combustible gas detectors market is comprised of hun-dreds of companies, with small niche suppliers and those with more prod-uct lines, systems, and strong service capabilities. However, going forward a strong trend is seen toward consolidation. Large suppliers are acquiring small manufacturers to increase their market share. Acquisition helps them to expand product lines and foray into new markets by acquiring new tech-nologies. The market is also observing new entrants through acquisitions.

Hyperspectral and infrared cameras are among the newer technologies gaining wider acceptance in recent times. These cameras can visualize various toxic and combustible gases to produce a picture of the scanned area in real-time. Well suited for detection of various types of volatile organic compounds (VOCs), these cam-

eras are becoming an attractive option for industries such as chemical and water & wastewater.

With China and India as the growth engines, Asia represents the greatest oppor-tunity for greenield projects for gas detec-tor suppliers. However, in these developing markets regulations are not enforced strictly. As a result, here users tend to be less con-cerned about reliability than about cost. With safety issues becoming a major point of concern for the governments of these coun-tries, this trend is predicted to change in the future. Many developing countries are tak-ing measures to address rising safety issues. As a result, end users in these regions have started to overlook the cost and pay more attention to reliability and performance of the detectors.

US natural polymer market to be worth

$7.12 billion in 2018U.S. natural polymer sales generated rev-

enues of $4.95 billion in 2012, according to the latest market report from Transparency Market Research (TMR). Demand is expected to remain on the rise in the next few years, growing at a compound annual rate of 6.2% between 2012 and 2018. If that prediction proves right, the market will be worth $7.12 billion by the end of the forecast period.

The publication attributes the expansion of the U.S. natural polymer market primar-ily to rising demand for non-petroleum based and environmentally friendly prod-ucts. Pharmaceutical applications are play-ing a major role in this growth amid accel-erating demand for excipients, binder and iller in directly compressed drugs, wound dressings and the treatment of arthritic joints, among other uses.

In terms of products, TMR segments the natural polymers market into cellulose ether, starch and fermentation products, protein-based polymers and others. Cellulose ether has been the dominant product category on the U.S. market when it comes to demand and this is expected

to remain the case throughout the forecast period. Cellulose ether is most widely used in medical applications, construction, oilfi elds, food and beverage, cosmetics and personal care products. In 2012, cellulose ether accounted for 36.5% of total U.S. consumption of natural polymers.

Cellulose is produced through the photosynthesis process of cotton, wood pulp and other plants. The list of key cellulose ethers features methyl cellulose (MC), hydroxyethyl cellulose (HEC), carboxymethyl cellulose

(CMC) and microcrystalline cellulose (MCC). MC has a vast range of uses, among them as thickener and emulsifi er in food and cosmetic products and a performance additive in construction materials. HEC is widely used in cosmetics, detergents and other household products. CMC also fi nds wide application in food production as a thickener and emulsion stabilizer. It is also employed as a thickening agent in pharmaceuticals, while the oil industry uses it as an ingredient of drilling mud. MCC is another term for

refi ned wood pulp and the pharmaceuti-cal industry uses it widely as an excipient. MCC can also be found in a wide range of processed foods, where it may be used as an anti-caking agent, stabilizer, texture modifi er or suspending agent.

As for starch and fermentation prod-ucts, sales in that category are expected to get a boost from rising demand for pharmaceutical applications. According to TMR, this segment will grow at a com-pound annual rate of 12% through 2018, when demand will reach 479.3 kilotons.

Petrochemical industry set for growth

in 2013Although not expanding at an aston-

ishing rate, the U.S. chemical and pet-rochemical industries are experiencing steady growth, a report from Business Monitor International (BMI) indicates.

Petrochemical producers are benefi t-ing from the low price of ethane and are set to achieve a robust performance this year, especially those related to recover-ing sectors, like the construction industry, but questions have been raised over the industry’s ability to implement the planned capacity expansion. If output increases in the long term, the surplus in production will have to be exported and many analysts are doubtful that this could happen.

The latest forecast for U.S. petrochemi-cal producers predicts a challenging time. Europe, one of the biggest markets for U.S. petrochemical production, is still in the grip of tough economic conditions, which have an impact on demand. Nevertheless, manufacturers in the United States have the competitive advantage of working with cheap ethane feedstock, enabling them to continue performing well.

The report found that over the fi rst four months of 2013 high-density polyethyl-ene exports grew 29% compared to the same period last year, reaching a total of 661,580 tons. Low-density polyethylene exports also rose but at a more modest rate, up 7.2 percent, to 234,534 tons. Similarly, exports of linear low-density polyethylene rose 11 percent, to 212,408 tons. Over the period between January and April, the biggest consumers of U.S. petrochemical products were Canada, Mexico and Brazil, the BMI stated.
