1. GENERAL BACKGROUND INFORMATION

ORGANIZATIONAL CONTEXT UNIDO is the specialized agency of the United Nations that promotes industrial development for poverty reduction, inclusive globalization and environmental sustainability. The mandate of UNIDO is to promote and accelerate sustainable industrial development in developing countries and economies in transition. With this mandate, the Organization carries out two core functions: as a global forum, it generates and disseminates industry-related knowledge; as a technical cooperation agency, it provides technical support, policy advice and implements projects. UNIDO's vision is a world where economic development is sustainable and economic progress is equitable. The Department of Trade, Investment and Innovation (TII) supports countries in their efforts to develop through trade, investment and innovation the potential of the manufacturing sector to drive socio-economic progress. The Department is responsible for assisting countries to strengthen competitiveness in global markets through capacity-building in quality, environmental sustainability, and social accountability requirements in accordance with international management system standards and private sector requirements. It supports the establishment of linkages between producers/processors in developing countries and local, regional and global value chains (retailer, manufacturers) by developing capacities in the area of product quality. PROJECT CONTEXT UNIDO is supporting Cuba’s efforts in investment and strategic alliance promotion endeavours for strengthening its industrial capabilities and competitiveness in priority industrial sectors through the formulation of a Country Programme Framework (CPF), in line with the economic and industrial transformations decided by the Government and with the UNDAF signed for 2014-2018. One of the priority CPF areas as per main outcomes agreed with the Government of Cuba is the development of an Industrial Upgrading and Modernization Programme (IUMP) focusing on priority agro-chemicals and agricultural machinery production sectors. Cuba IUMP aims to contribute to inclusive and sustainable industrial development of Cuba and improve food security through upgrading and modernization of industrial sectors of Fertilizers and Agricultural Machinery. This will be achieved through enhancement of industrial performance and competitiveness of pilot enterprises operating in the Fertilizers and Agricultural Machinery industrial sectors within the existing industrial hubs. The programme will be implemented via three mains modules: sectoral analysis and building a strategic action plan for the Cuban priority Fertilizers and Agricultural Machinery industrial product lines/sub-sectors; enterprise diagnosis and industrial upgrading of selected pilot manufacturing enterprises operating within the identified priority sub-sectors/existing hubs; and strengthening human and technical capacities of national counterpart institutions/expertise in the provision of enterprise diagnosis and industrial modernization, sectoral analysis and other best practices.

LOT 2 – PIPING - Technical Specifications

This specification is built around the ball valves to be ordered, from which the suggested pipe and component/fittings dimensions result. This includes as well a wall thickness suggestion.

This welding gap 1 (see the figure below) is the difference between tube outside diameter and inside diameter of the "plate slip on flange for welding", EN 1092-1, PN 16, type 01. This welding gap should be such that the tube is slipped into the flange with a small tolerance clearance. This has led to the tube choice described below.

(2) Technical Information / Assumptions

a. The piping system according to EN DIN 10217-7 and the related norms is planned to be installed to assure that all parts (pipe, fittings, flanges, valves) fit together

b. The material for all valves should have the same qualifications as 316 L

c. The material of the gaskets should correspond to the media specified in the enclosed Excel.

i. From the 10 ball valves with a Nominal Width NW of 50 mm, 7 are charged with 50% nitric acid; temperature for all will be 40 degrees C.

ii. The 2 - NW 200 ball valves have nitric acid vapors as medium, temperature max 90 degrees C. pH = 1

iii. The 2 - 150 NW ball valves are charged with calcium hydroxide (CaOH)2, pH approximately 11, at room temperature.

iv. Of the total of 37 ball valves with NW 80 - 5 are transporting water or air. The remaining 32 are transporting liquid calcium nitrate fertilizer with a un pH> 3; temperature up to 80 degree C.

v. NW / ND 40 ball valves) have maximum temperatures of 40 degrees. 15 NW: Nominal Width 16 ND: Nominal Width for Selected Pipe 17 PN: Nominal pressure

28

d. Inner diameter / bore: the free ball diameter of the valve should correspond approximately to the nominal pipe diameter, as stated above under "suggested proposed pipe NW". This pipe specification has been adapted to the ball valves (according to EN 10217-7. No reduction in the ball, since e.g. the 32 pieces NW 80 process ball valves are for liquid calcium nitrate, which is partly loaded with a suspension of soft solids.

e. It has been observed that the 3-piece ball valves, if short and flanged, have a reduced bore. Accordingly, preferred is the 2-piece short and flanged version.

f. According to to norm, flanges of the ball valves NW 40 and NW 50 have 4 holes, the others beginning with NW 80 - 8 holes.

LOT 4 - FILTER PRESS - Technical Specifications

The Process

A new production for liquid Calciumnitrate fertilizer will be invested in the existing Nuevitas fertilizer plant in Cuba. The process will be a batch process with intermitted working reactors, each 3,2 m3. For the chemical reaction Nitric acid and Ca(OH)2 are added while being stirred and the resulting product is liquid Calciumnitrate as solution. This solution has due to the impurities of the raw material Ca(OH)2 particles, which did not take part in the reaction, and furthermore due to Ca(OH)2´s current particle size of maximum 2 mm also unreacted / undissolved Ca(OH)2 particles.

It is considered that the filter must be able to assimilate all the contents of the reactor to be filtered in one hour. Each reactor is supplied first with 2900 L of 50% nitric acid for 30 minutes and 1200 kg of lime hydrate at 70% CaO for 4 hours at a flow of 300 kg / h in an exothermic reaction, with constant agitation.

The suspension obtained in the reactor (3.2 kl of calcium nitrate) is directed by gravity to the intermediate tank, this process will take approximately 30 minutes. Then the product is sucked by the filter press pump, which must drive the liquid through the plates with the filtering material.

Note: If the filter press requires filtering aid, it must be supplied to the equipment in 40 minutes, before filtering the calcium nitrate suspension that comes from the intermediate tank.

The filtration of the suspension obtained in the reactor will take 60 minutes, so when talking about two reactors, it would be 2 consecutive hours (first one and then the other reactor). The cleaning of the filter should take around 90 minutes and the preparation of this equipment for the next filtering operation should be 30 minutes. Then the filtered solution is taken to the storage tank and about 6.4 kl would be obtained, because there are two reactors.

Note: the complete operation of the filter consists of the following fundamental steps:

1. Filter preparation: 30 minutes 2. Filtration process of the suspension of the reactors: 120 minutes 3. Cleaning the equipment: 90 minutes

It is recommended that the filter material should be cleaned every 32 kl of filtration or when ΔP≥2 bar. As the exact measurements for the solids concentration after the reactor or after the regulation reservoir and before the filter are not available yet, there are some comments that may provide rough conditions relevant for your press design:

Instead of Calciumcarbonate with max 200 micron like Fertiberia and Liquimed we are using Ca(OH)2 with particle sizes up to 2 mm. This will contribute to a certain degree to undissolved matter.

Our Ca(OH)2 has impuritites up to 7%, contributing as well to undissolved matter.

Until now the separation of these suspended solids was effected by a sedimentation process. After careful studying the matter and visiting similar plants, a filter press for this separation process will be introduced. The filter press will have to comply with the following process data: • Input data

— Fluid: Aqueous suspension of calcium nitrate with 50% concentration expressed as calcium nitrate > Product to be filtered: calcium nitrate 50%

— Maximum volume to filter: 4 m3/h

— Fluid density: 1,505 kg/dm3

— Fluid temperature at the filter inlet: 65 to 80°C

35

— Amount of suspended particles due to raw material impurities and undissolved matter: 5% (m/m) approximately in the form of sludge (1.73% (m/m) dry residue) for each 3.2 m3 reactor. The mass balance says that these impurities represent a contribution of 176 kg dry substance per daily production of 10,18 tons

— Sizes of suspended particles

i. Less than 230 Mesh (0.06 mm): 20%

ii. Between 230 and 100 Mesh (between 0.06 and 0.15 mm): 77%

iii. Greater than 100 Mesh (0.15 mm): 3%.

• Output data - Final product to be obtained

— Calcium oxide concentration greater than 16.7-17.4%.

— pH = 5.5 - 6.5

— Density of 1.46 - 1.55 kg / m3

— Calcium nitrate concentration of 49-51%

— Maximum particle size 120 microns

• Scope of supply, machine data and infrastructure

— The filter press complete in a plug & play configuration. This includes the feed pump (1 + 1 spare pump) before the press, to supply the input to the filter press situated on a level of approximately 5. The filter pump installed on ground level.

— Material: 316 L stainless steel

— The feed pump will have positive suction, it is at the level of the collector tank and will send the fluid to the filter press that is to 5 m of height.

— Filter cleaning system: Mechanical cleaning with pressurized water and chemical cleaning

— Electricity 440 V, 60 Hz

LOT 6 - BLOW FORMING MACHINE - Technical Specifications

The requested equipment should meet the following specification:

(1) Product to be packed – 50% liquid Calciumnitrate fertilizer:

Characteristics of the final product:

• Concentration of calcium oxide greater than 16.7-17.4%. • or pH = 5.5 - 6.5 • Density of 1,46 - 1,55 kg / m3 • Concentration of calcium nitrate of 49 - 51%

(2) Required production capacity

The required production capacity is given with the table below:

Accordingly the capacity should allow a yearly production of app. 72.000 containers – 5 L and 126.000 containers 20 L. The 200 L containers are provided from an existing production.

Please indicate, according to your experience, for the 5 L and the 20 L containers,

• which capacity you would expect in 1 – and 2 daily 8-hour shifts, without changing the product – based on some cycle times,

• how much time you consider necessary for change of product at the end of a shift,

• how much time you consider necessary if we stop the machine after a full continuous operation period and start it again and how much material loss or waste production you expect in case of a complete new start.

Very likely it will be reasonable not to change the product frequently and produce as many shifts as possible without interruptions. Regarding the fertilizer plant we intend to run it 2 shifts at 8 hrs per day and 220 days a year. But the container production will take place at a separate location.

The machine to be selected shall have some reserve capacity – see also below, which allows consideration of this in a shift plan.

In accordance to that, the production plan is to be developed.

LOT 7 - INJECTION MOLDING MACHINE - Technical Specifications

The requested equipment should meet the following specification:

(1) Product to be packed – 50% liquid Calciumnitrate fertilizer:

• Product to be packed: 50% liquid calcium nitrate • Characteristics of the final product:

— Concentration of calcium oxide greater than 16.7-17.4%. — or pH = 5.5 - 6.5 — Density of 1,46 - 1,55 kg / m3 — Concentration of calcium nitrate of 49 - 51%

(2) Specification of the caps:

a. Specification of the 5 L cap

Figure 1. Estimated dimensions of the lid for the 5-liter drum. These dimensions are currently valid to estimate the cavities to design the size of the mold and accordingly select the injection machine.

Figure 2 and 3 show the covers before closing the package (it has the security seal) and after opening the package (without the security seal). It also shows the obturator piece that is placed between the mouth of the drum and the lid. The pictures apply for the 20 L container, but we assume, that they apply as well for the 5 L container.

Nomenclature of figure 2 and 3 A: shutter / obturator B: cover without security seal C: lid with security seal C1: security seal

By incorporating the seal on the lid in the mold, it would not be necessary to produce seperately or purchase a security seal.

Figure 4. The relevant container

Body material: HDPE Lid material: PP Height: 283 mm Width: 180 mm Depth: 137 mm Diameter of the mouth: 27 mm Weight: 165 - 195 grams

b. Specification of the 20 L cap

Figure 5. Estimated dimensions of the lid for the 20-liter drum. The shown measures of the lid are approximate, allowing to receive an offer for the injection machine. The measures could be taken as a reference so that the cavities and the size of the mold can be calculated to determine the size of the injection machine.

The precise measurements on the type of thread, the step, the depth, etc., will be available when the mold and die company will provide them to the customer. Therefore these dimensions are currently valid to estimate the cavities to design the size of the mold and accordingly select the injection machine.

These measurements represent an extrapolation of a similar cover whose measurements according to the German standard DIN 61 are as follows: a = 55.70; b = 60.50; c = 21.70.

Figure 2 and 3 above show the covers before closing the package (it has the security seal) and after opening the package (without the security seal). It also shows the obturator piece that is placed between the mouth of the drum and the lid. The pictures apply for the 20 L container.

(3) Specification of capacity for the products to be produced by the injection molding machine, the 5 L and the 20 L caps and also the shutters / obturators

Figure 8. Quantities

The caps of the 200 L containers are of no interest for the machine, they get them from a separate source.

Some capacity percentage for waste production might be included.
