Pilot North-Labatyugan field exploitation began in 2004. Introducing innovative technologies of oil production, Surgutneftegas immediately became concerned with the recovery of APG by generating electricity. The first GTPP with a capacity of 24 MW was commissioned here in 2007. The start-up in 2011 of the second phase - GTPP with a capacity of 36 MW - allowed to fully meeting the needs of the field.

GTPP-36, located at the site of booster pump station No.3, operates in a simple cycle. It consists of three power units produced by Sumy NPO. Each power unit is based on a gas turbine NK-16ST (KMPO) with a rated capacity of 12 MW and an efficiency of 29%.

The treatment of associated gas at this facility, as well as on GTPP-24, is carried out by BCS of the hangar type, commissioned by specialists of the ENERGAS Group. It consists of six compressor units (CU), made based on screw oil-filled compressors. CU with unit capacity of 10,000 m3 / h are located in two separate buildings.



These aggregates compress the APG to 2.7 MPa. For gas purification high-efficiency filters-scrubbers are designed, which are located at the inlet to the CU and perform 2-step removal of liquid fractions and solid particles.

At the discharge line of the units there is built gas coolers so as to cool gas below the dew-point in order to separate condensate formed. Then the gas flows to the heaters, which maintain the design temperature of the fuel feeding to the turbines.

Each CU is equipped with a two-level system of capacity control and automated control system.

The project is notable for the fact that BCS simultaneously solves different tasks:

• three CUs treat APG coming from the gas gathering facility, compress it to 2.7 MPa and feed it to GTPP-36 turbines;
• other three CUs inject associated gas into the pipeline for transportation to GTPP of other fields.
