KIMRAY, Inc. Okla. City, OKGLYCOL ENERGY EXCHANGE PUMPS

INTRODUCTION:

The Glycol Energy Exchange Pump, “PressureVolume” or “PV-Series” Pump was developed in1957. The initial consideration was a pump thatwould utilize the energy of the wet glycol atabsorber pressure as a source of power. Withinthe confines of a system, energy can neither becreated nor destroyed. Energy can, however, bestored, transferred, or changed from one form toanother. The PV Series Pump transfers the energyavailable from the wet glycol, at absorber pres-sure, to an “equivalent” volume of dry glycol atreboiler pressure. In order to circulate the glycol,additional energy is needed to overcome frictionlosses within the pump

and connecting piping. This additional energy issupplied by gas at absorber pressure.

The pump was designed as double actingwith a maximum working pressure of 1500 psigwith a factor of safety of ten. Corrosion and weardictated use of the best materials available. Thesematerials include stainless steel, hard chrome plat-ing, nylon, Teflon, stellite, and “O”-rings speciallycompounded for glycol service. The pump containstwo basic moving parts, a Piston-Rod Assembly,and a Pilot Piston. Each actuates a three-way D-slide.

OPERATION:

The Kimray glycol pump is double acting, powered by WetGlycol and a small quantity of gas at absorber pressure (Red).Yellow denotes Wet Glycol (Blue) is being pumped to theabsorber. Green is Dry Glycol suction from the reboiler.

Wet Glycol (Red) from the absorber flows through port #4and is throttled through the SPEED CONTROL VALVE to theleft end of the Pump Piston Assembly, moving this assemblyfrom left to right. Dry Glycol (Blue) is being pumped from the leftcylinder to the absorber while the right cylinder is being filledwith Dry Glycol (Green) from the reboiler. At he same time WetGlycol (Yellow) is discharging from the right end of the PumpPiston Assembly to a low pressure or atmospheric system.

As the Pump Piston Assembly nears the end of its stroke, thePOSITION RING on the PISTON ROD contacts the right end ofthe ACTUATOR. Further movement

to the right moves the ACTUATOR and PUMP “D” SLIDE touncover port #1 and communicate ports #2 and #3. Thisexhausts Wet Glycol (Red) to the right end of the PILOT PIS-TON. This causes the PILOT PISTON and PILOT “D” SLIDE tobe driven from right to left.

In its new position the PILOT “D” SLIDE uncoversport #5 and communicates ports #4 and #6. THis exhausts WetGlycol (Red) from the left end of the Pump Piston Assemblythrough ports #4 and #6 to the low pressure Wet Glycol (Yellow)system. Port #5 (which was communicated with port #6) nowadmits Wet Glycol (Red) through the right hand SPEED CON-TROL VALVE to the right end of the Pump Piston Assembly.

The Pump Piston Assembly;y now starts the strokefrom right to left. Follow above procedure reversing directions offlow..

PRINCIPLE OF OPERATION:

Actions of each of the two basic parts of the pump are com-pletely dependent upon the other. The pilot D-slide actuated bythe Pilot Piston alternately feeds and exhausts absorber pres-sure to the power cylinders at opposite ends of the Piston-RodAssembly. Likewise, the Pump D-slide actuated by the Piston-Rod Assembly alternately feeds and exhausts absorber pres-sure to opposite ends of the Pilot Piston.

The force to circulate glycol within the dehydration system issupplied by absorber pressure acting on the area of the PistonRod at its O-ring seals. The area of the Piston Rod is approxi-mately 20 percent of that of the Piston. Neglecting pump frictionand line losses, the resultant force is sufficient to produce a the-oretical discharge pressure 25 percent greater than absorberpressure. The theoretical discharge pressure, for example, at300 psig absorber pressure would be 1875 lbs. This theoretical“over-pressure” would develop against a blocked discharge linebut is not sufficient to cause damage or create a hazard.

Approximately 25 to 30 psig pressure is required to overcomepump friction leaving the additional “over pressure” for line loss-es and circulation. It is recommended that these losses be heldto approximately 10 percent of the absorber pressure or asnoted in catalog.

Two Speed Control Valves are provided to regulate the flowof wet glycol and gas to and from the power cylinders.Reversing the direction of flow through the Speed ControlValves provides a flushing action which cleans the valve orifices.

If the wet glycol, returning to the pump from the absorberwere to be completely fill the cylinder, no additional gas wouldbe needed. However, the wet glycol will only occupy approxi-mately 65 percent of the total volume of the cylinder and con-necting tubing leaving 35 percent to be filled by gas from theabsorber. This gas volume amounts to 1.7S.C.F. per gallon ofdry glycol at 300 psig absorber pressure and 8.3S.C.F. at 1500psig and may be considered as continuing power cost for pumpoperation. This gas can be utilized in the regeneration processof the dehydrator for “rolling” and or “stripping” purposes. It mayalso be recovered in a low pressure glycol gas separator andused to fire the reboiler pressure glycol gas separator and usedto fire the reboiler.

By supplying some absorber gas to the cylinders, the wet gly-col level is maintained at the wet glycol outlet connection on theabsorber and eliminates the need of a liquid level controller andits attendent problems. Excess liquids such as hydrocarbonsare removed from the absorber at approximately 55 percent ofthe pump rate, reducing the hazard of dumping a large volumeof hydrocarbons into the reboiler as would be the case with aliquid level controller.

INSTALLATION:

A number of considerations should be made withregard to pump installation since it is the “heart” of a dehydra-tion system. It is a moving mechanical device subject to wearand will ultimately need repair. Location of the pump is veryimportant. East access to the pump for repair or exchange cansave time and trouble.

Test connections (1/4” NPT with valve) located on thepiping to and from the pump permit a fast means of troubleshooting pipe restrictions or blockage.

Filters, which are discussed later, should always beinstalled in the wet glycol piping between the absorber andpump and in the suction line to the pump, with provisions madefor maintenance of the filters.

Suction piping should preferably be large enough topermit a positive feed to the pump. Feed pressure must bemore than 4 or 5 inches of Hg vacuum to prevent pump cavita-tion.

Where two or more pumps are manifolded together, the totalcapacity must be considered in the piping design. Also, a mani-fold should be designed to provide each pump with its“Fairshare” of the wet glycol from the absorber. It is not neces-sary that the proportion be exact.

Pumps with lower “pumping ratios” are available toprovide additional energy for pressures below 300 psig; but is itbetter not to use these pumps at pressures above 400 or 500psig because of excess gas consumption. Conversion kits areavailable to change standard pumps to “SC” pumps with declin-ing field pressures.

PUMP SHUTDOWNS:

Pump shut-down mechanisms, which require noadjustment and are controlled by the discharge of dry glycol,are available. The Kimray ASD Shutdown is a check devicewhich permits pump operation as long as dry glycol is being dis-charged from the pump. (See page 10.26 for description ofoperation.)

GLYCOL ENERGY EXCHANGE PUMPS 1500 Lb. W.P.

HEAT EXCHANGERS:Sufficient heat exchange is necessary to reduce dry glycol

suction temperature to at least 200°F, preferably to 150°F.

SPLIT DISCHARGE CHECK VALVE BLOCK:Kimray Glycol Pumps are available with check valve blocks

for split discharge to serve two absorbers on a dehydration unit.See page 10.29 for a description.

VITON “O” RINGS:Viton “O” rings for all moving seals in th Kimray Glycol Pumps

are available. Viton repair kits can be ordered for pumps alreadyin operation or new pumps can be ordered with viton “O” ringsat additional cost.

Viton “O” rings are recommended for use when liquid hydro-carbons are found in the gas, for CO2 service or for elevated

operating temperatures. Under normal conditions (without theabove problems) viton “O” rings will not give as long of a servicelife in the pump as standard Buna-N “O” rings.

SYSTEM PRESSURE DROPS:The Kimray Glycol Pumps are designed to operate by using

the energy from the wet glycol and some additional energy inthe form of gas at absorber pressure. Excessive pressure dropsin the lines connecting the pump to the system can cause thepump to run erratically or stall. The following conditions shouldbe designed into the system to assure proper pump perfor-mance:

DRY GLYCOL SUCTION LINE: Size the suction line, lowpressure filter and heat exchanger such that the pump willhave a positive pressure at the suction inlet when running atthe maximum rated speed. This line may need to be largerthan the pipe fitting on the suction check valve block. (Seepipe connection sizes on page 10.28.)

WET GLYCOL POWER LINE: Recommended line size is thesame as the size of the pipe connection for the given pump.(Page 10.28) The pressure drop across the high pressure filteris a factor in considering the total system pressure drop.

DRY GLYCOL DISCHARGE LINE: Recommended line size isthe same as the size of the pipe connectionfor the given pumpand the absorber should be full opening to the recommendedline size.

WET GLYCOL DISCHARGE LINE: Recommended line sizeis the same as the size of the pipe connection for th egivenpump. (Page 10.28.) If a glycol gas separator is used, thepressure maintained on teh separator must be considered inthe total system pressure drop. Also, heat exchanger coils inaccumulator tanks also add tothis pressure drop.

ISOLATING VALVES: All plug, gate, or blocking valvesshould be full opening to the recomended line size of the givenpump.

If a positive feed is supplied to the pump at the dry suctioninlet, the total system pressure drop will be the sum of the fol-lowing pressure drops:

1. The pressure drop between the absorber and the pump inthe wet glycol line.

2. The pressure drop between the pump and the absorber inthe dry glycol discharge line including any pressure required toopen and establish full flow in any check valves.

3. The pressure drop between the pump and the reboiler (atatmospheric pressure) in the wet glycol discharge line. Thisincludes the liquid head to the reboiler, heat exchanger coil,and/or the pressure maintained on a glycol seperator.k

The sum of these pressure drops gives the total “system pres-sure drop”. The graphs on pages 10.11-10.15 give the maxi-mum total system pressures and their effect on pump output.Exceeding the total allowable system pressure drop will causethe pump to run erratically or to stall.

To determine if a problem exists in an operating dehydrationsystem, slowly open the speed control valves on the pump untilit runs at the maximum recommended pump speed. (See graphpage 10.8.) If the Pump cavitates before reaching the maximumpump speed, the suction line is restricted. If the pump will notrun at the maximum rated speed, then there are probablyrestrictions in one or more of the other three connecting lines.

FILTERS:Filters should be used on every dehydrator for protection of

both the pump and reboiler. Many pumps are severely damagedin the first minutes or days of operation from flow line and ves-sel debris. Reboilers have been known to be filled with sandwhich had to first pass through the pump.

Filters should give protection from 25 to 150 micron particlesizes depending on the specific condition. The disc type,microin type, and sock type have all proven very satisfactory ifthey are properly maintained. Some metal filters are equippedwith a cleaning device which should be operated daily or atleast every few days as experience may dictate. Sock filtersmust be replaced at regular intervals. Preventative maintenanceon these filters will save many dollars in major pump and reboil-er repairs plus the reduction of costly down time.

A spring loaded by-pass on the filter is not recommended. It isbetter for the pump to stall due to lack of power than beexposed to dirt and grit from an open by-pass. Always install ahigh pressure filter between the absorber and the pump. A filteron the wet glycol discharge of the pump will protect the reboilerbut does nothing for the pump. A low pressure filter on thepump suction protects against metallic particles from a newreboiler and its connecting piping. Filters will also keep the gly-col free of heavy tars and residue from evaporated hydrocar-bons and resinous compounds caused by polymerization of theglycol. Sock type filters are probably best for this type of filtra-tion but should be changed rather frequently.

In addition to using filters it is often necessary to make achemical analysis of the glycol, not only for pump protection butfor better dehydration. Organic acids in glycol are producedfrom oxidation, thermal decomposition, and acid gases from thegas stream. These acids cause sorrosion in the system, anddissolve the plating on pump parts in a short time. Glycol acidityshould be maintained between a pH of 7 to 9. Alkaline aminesare usually recommended to control the pH value because theywill neutralize any acid gases present and are easily regenerat-ed.

G:10.4Issued 12/83

Another glycol contaminate which causes pump problems issalt. Salt water which continues to enter a dehydration systemsoon produces a super saturated condition in the reboiler. Thisresults in salt deposits in the lines and in the pump as the hotglycol is cooled. A complete cleaning and washing of the entiresystem is required to remove the salt.

OPERATION:

A new pump or new dehydrator should be put into operationby first bringing the glycol circulation and operating temperatureto an equilibrium condition by using 300 to 400 psig absorberpressure. This can be done with or without gas flow. If it is easi-er to start up under a no-flow condition, only enough gas needbe supplied the absorber to maintain the pressure. In mostinstances the pump will pick up its prime without help andshould do so in a few strokes. If the pump does not prime imme-diately, the dry glycol discharge should be opened to atmo-sphere until glycol discharges from both cylinders. When equi-librium has been established, the pump should be stopped anthe absorber pressure increased for operation. Pump speed canthen be reestablished to the desired rate.

The maximum operating temperature of the pump is limited bythe moving “O”-ring seals and nylon D-slides. A maximum of200 degrees is recommended. Packing life will be extendedconsiderably at 150 degrees.

KIMRAY, Inc. Okla. City, OKGLYCOL ENERGY EXCHANGE PUMPS 1500 Lb. W.P.

Always stop the pump when the pump when the main gas flowis turned off. A pump which continues to circulate with no gasflow elevates the complete dehydrator temperature, and in timeto reboiler temperature.

If a pump has been deactivated for several months, the checkvalves should be removed and inspected before attempting tooperate the pump. The pump startup should be similar to that ofa new pump by first bringing the system to equilibrium.

TROUBLE SHOOTING:

If a glycol pump has been operating in a clean system it isvery likely that no major service will be required for severalyears. Only a yearly replacement of packing will be required.Normally the pump will not stop pumping unless some internalpart has been bent, worn, or broken, or some foreign object hasfouled the pump, or the system has lost its glycol.

A pump which has been running without glycol for some timeshould be checked before returning to normal service. Probablythe pump will need at least new “O”-rings. The cylinders andpiston rods may also have been scored from the “dry run”

Following are some typical symptoms and causes. These arepresented to assist in an accurate diagnosis of trouble.

SYMPTOMS

1. The pump will not operate.

2. The pump will start and run until the glycol returns fromthe absorber. The pump then stops or slows appreciablyand will not run at its rated speed.

3. The pump operates until the system temperature is nor-mal then the pump speeds up and cavitates.

4. The pump lopes or pumps on one side only.

5. Pump stops and leaks excessive gas from wet glycol dis-charge.

6. Erratic pump speed. Pump changes speed every few min-utes.

7. Broken Pilot Piston.

CAUSES

1. One or more of the flow lines to the pump are completelyblocked or the system pressure is too low for standardpumps (below 300 lbs.) use “SC” pumps below 300 lbs.

2. The wet glycol discharge line to thereboiler is restricted.A pressure gauge installed on teh line will show therestriction immediately.

3. The suction line istoo small and increase in temperatureand pumping rate cavitates the pump.

4. A leaky check valve, a foreign object lodged under acheck valve or a leaky piston seal.

5. Look for metal chips or shavings under the pump D-sildes.

6. Traps in the wet glycol power piping sends alternateslugs of glycol and gas to the pump.

7. Insufficient glycol to the Main Piston D-slide ports.Elevate the control valve end of hte pump to correct.

Bleed valves “A” and ”B” are required for removing pressurefrom the pump to allow inspection and repair. Bleed valve “A” isalso used for priming as described below. The plug valves andunions permit the pump and filters to be easily isolated orremoved for inspection or repair.

OPERATING PROCEDURE:1. Close both speed control valves, bleed valves “A”, “B” and

plug valve “C”.2. Open plug valves “D” and “E”.3. Pressure absorber to about 300 psig.4. With plug valve “C” closed, open bleed valve “A”.5. Slowly open both speed control valves until pump is running

about 1/3 rated max. strokes per minute. Count one strokefor each DISCHARGE of PUMP. When dry glycol dischargesfrom valve “A” on each stroke, the pump is primed. Closevalve “A” and open valve “C”. Readjust speed control valvesto 1/3 rated max. strokes per minute and continue operatingpump until wet glycol returns from the absorber to the pump.This will be evidenced when the pump tries to meter liquidthrough the speed control valves instead of gas and causesthe pump to slow down. Close both speed control valves.

6. Bring absorber to full operating pressure.7. Adjust speed control valves for desired rate (see capacity

chart).8. Inspect and clean filters and strainers periodically.9. For preventive maintenance, “O” Rings should be replaced

annually. To check “O” Ring seal, close valve “C”. If pumpcontinues to run, seals should be replaced.

SYSTEM SHUTDOWN:

1. Close plug valve “D” Allow pump to stop running2. Close plug valve “C” and “E”3. Bleed pressure from bleed valve “A” and “C”

Kimray Glycol Pumps are available with check valve blocksfor split discharge to serve two absorbers on a dehydration unit.On an original pump purchase there is no extra charge for thischeck block.

An accurately divided flow is assured since each absorber isserved by one cylinder of the double acting pump.
