Odessa Region
Main Technical Data
Type of gas...........................................Natural gas
Engine type........................................4 x JMS 420
Electrical output................................4 x 1 416 kW
Thermal output..................................4 x 1 498 kW
Start-up.........................................................2007

Description
Gas power plant was designed as an independent power supply of electrical and thermal power for the processing needs of the plant. The fulfillment of technical specifications “Odessaoblenergo” as for the connection of the total capacity 5 MW would demand significant capital costs, which wouldn’t be paid back in the future. As a result, the construction of the independent gas power plant became economically reasonable.
The independent power plant can fulfill not only the power supply needs of the plant, but also thanks to the lower self cost of the generated electrical and thermal power it is possible to reduce the self cost of the main products of the oil and fat plant.

Main Technical Data
Type of gas.............................................Natural gas
Engine type….......................................2 х JMS 420
Electrical output...................................2 х 1413 kW
Thermal output.....................................2 х 1442 kW
Start-up...........................................................2010

Description
The reasonability of cogeneration implementation at “Sandora” plant was very vital, as fuel utilization enables to get three types of necessary power, not only electrical and thermal, but also cold of absorbtion machines. The coefficient of fuel utilization exceeded 90% and the calculated payback period appeared to be less than three years that speaks very positively about the introduction of equipment.

Biogas refinery plant SBR,
биогазов SBR,
Kogel, Germany
Main Technical Data
Type of gas....................................................Biogas
Engine type..............................1 x JMC 420 GS-B.L
Electrical output………....…........................1 413 kW
Thermal output.............................................751 kW
Steam production.........................1 037 kg/h at 3 bar
Start up………………….......................October, 2003

Description
The plant, running on biogas, utilizes the wastes of hospitals, hotels and canteens and also organic wastes of food industry. The collected biogas is used as fuel for the Jenbacher gas engines. The generated electricity is transferred totally to the electric power grid, the engine exhaust gases heat is used for steam production. The steam is used for pasteurizing of wastes, which then are used as sterilized fertilizers.
