At West-Chigorinskoye field there is operating an auxiliaries gas turbine power plant.

This GTPP is the fifteenth power plant operating at the fields of JJSC “Surgutneftegas”. To date, the total capacity of the company's generating equipment has reached 380 MW. Until 2010, it is planned to increase this figure to 500 megawatts of own capacities.

The base of the plant consists of two gas turbine units GTA-6RM, designed and manufactured by NPO Saturn and OJSC Saturn-Gas Turbines. The installed capacity of the GTPP is 12 MW.

As fuel, there is used associated petroleum gas, coming from the last stages of oil separation. The implementation of the project allowed increasing the share of APG recovery at “Surgutneftegas” production facilities to 94.5%.

At the GTPP there is operating a fuel gas booster compressor station of the company ENERGAS. The BCS includes three compressor units that purify and compress APG to 2.7 MPa for its subsequent feeding to the turbines.

The units (pictured below) are based on screw oil-filled compressors; they include a reliable multi-stage filtration system, as well as a system for maintaining the design temperature of the gas feeding, so that gas at the outlet meets the established requirements for purity, pressure and temperature.

Supply of booster compressor equipment and performance of the whole complex of pre-launch activities, including erection supervision, commissioning and testing, were carried out by the technicians and engineers of ENERGAS.
