Construction of the new 29 MWh turbine

VKG Energia is a subsidiary of the VKG company (Viru Keemia Grupp, Estonia). Gas from processing the shale constitutes the main raw material in VKG Oil. When the factory Petroter I started working, the amount of generated high-calorie-content gases and vapors increased significantly, so the decision was taken to construct a new turbine for processing such gases and vapors into heat and electric power.

In 2007, Ekobana UAB engaged into the project of the new turbine for VKG Energia. Installation of the turbine was not easy:

the construction continued for several years, the economic crisis has started and funding for the project was suspended at the time when turbine components were already supplied; they were waiting for almost two years until installation in turbine workshop. At the same time, new infrastructure was also created. This included a circulation pump station with the circulating waterlines, a separate automatic fire extinguishing system, 6 ventilation cooler modules and the construction of building for the new unit.

In June of 2011, the turbine was started for a test with connection into the energy system, and from August the turbine began its steady regular job. Power of the new turbine is 29 MW, and it increases the amount of electricity produced in the company approximately by 40%. Also, the Coefficient of Performance of the new turbine is approximately two times better than COP of the old equipment.

Water supply and sewage networks development and renovation in Trakai - stages 1 and 2

In the frame of implementation of investment program package – stages 1 and 2 - for the upper reaches of Nemunas River Basin, the project "Water supply and sewage networks development and renovation in Trakai - stages 1 and 2” was completed in Trakai district municipality together with partners Lonsta UAB and Pozemines Jungtys UAB under the conditions of FIDIC “the Red Book” contract.
Seven new sewage pumping stations were constructed with control cabinets and 27.410 km of pipelines were installed as follows: 12.07 km of water networks, self-flowing water networks – 11.533 km, pressure-water networks – 3.810 km.

Reconstruction of boiler flow diagram

Under the construction contract Ekobana UAB has successfully completed the reconstruction of the boiler flow diagram in Kaunas Heat and Power Plant. The scope included design, equipment supply, installation and commissioning works.
The goal of the reconstruction was to install the additional network pumps with frequency converters, which supply the returning heating water to the boiler and can keep a pressure of network water under the boiler or the amount of network water through the boilers. These parameters are kept according to the set value in the controller.
To achieve this, two Grundfos TP-200 pumps (with 200 kW el. engines) were installed, each with a capacity of up to 1,000 m3/h and max pressure of up to 95m; installation also included frequency converters Danfoss FC-202, pressure transducers DF-65, valves DN350, DN400, and PN25; power distribution cabinet was reconstructed, cables wired, automatic control cabinet was mounted, allowing the pumps to work according to the flow or pressure settings.

Feed phosphates shop construction

Monocalcium phosphate (feed phosphates) is used as an additive for animal or birds feed. The addition of monocalcium phosphate to the feed gives the animals calcium and phosphorus they need to promote formation of strong bones, increase energy and protein metabolism, improve functioning of reproductive, nervous and immune systems, increase productivity of animals. Mineral supplements of this composition are especially suitable for herbivorous animals.

In response to the increased demand for feed phosphates in the global market, the Eurochem Group, which owns chemical plant Lifosa in Kėdainiai, has decided to extend the production of above mention feed phosphates. It was decided to build a new modern plant in Lifosa. Ekobana UAB has won the tender for construction of this plant, while stock company Montuotojas (Panevežys division) has won the tender for construction of plant for preparation of raw materials, packaging and warehousing of finished products.

The contracts with the winners have been signed in March 2009. Technical project has been prepared in close cooperation with specialists and engineers of the factory, and the construction and ordering of equipment has begun immediately. The main technological equipment has been manufactured by the German companies Allgaier, Rhewum and Mioller.

Not only the production line, but also spacious production warehouse of 4,000 square meters was installed. It has special individual ramps for transporting feed phosphates with trucks and/or rail, in 25 kg or 1 ton packs and/or bulk products. In the same warehouse, packaging equipment is installed with capacity: for bags of 1 ton - 50 tons per hour, and for bags of 25 kg - 25 t/h. In the stage of designing, and then when selecting the technological equipment, special attention was paid to the production quality. In the production line, automatic feed phosphate pellet samplers and pellet analyzers are installed. Detailed information about the quality of the products is directly transferred to the operator, who manages the production process. Similar equipment is also installed in the production warehouse, cargo compartment. With the implementation of this project Lifosa AB took another step in the direction of environmental protection. Effective dust collection and absorption devices are active in the new plant, therefore the dust resulting from manufacturing process does not enter into the environment.

For the staff, whose number had not been reduced, working conditions has also improved: the whole production process is automated, operators are working in the spacious control rooms. Modern and spacious daily comfort premises, dining rooms, and recreation areas were equipped.

Lifosa AB began feed phosphate production in 2001. Currently, the company produces mono-calcium phosphate; 42,500 tons of it was produced in 2009.
