In December 2006, ENERGAS commissioned four booster compressor stations (BCS) for the gas turbine power plants of PJSC Surgutneftegas operating in the fields of the Khanty-Mansi Autonomous Area. These are Konitlor GTPP with a capacity of 24 MW (GTPP-24), West-Kamynskaya GTPP-24, Muryaun GTPP-24 and Yukyaun GTPP-36.



Power plants based on NK-16ST turbines (KMPO) were built as part of an energy project of Surgutneftegas to create its own generating capacities. The GTPPs use associated petroleum gas as a fuel. Thus, the provision of electricity for the production and infrastructure facilities is combined with the rational utilization of APG and improvement of ecological situation at the fields.

The first contract of ENERGAS for the supply of equipment for the oil and gas complex also included the associated gas BCS for the North-Labatyugan GTPP-24, which was launched in April 2007.

Compressor stations of the hangar type supply turbines with fuel with the required parameters for purity, temperature, pressure and flow rate. Each BCS consists of three compressor units (CUs) which housed in separate building.

The gas booster units are made based on screw oil-filled compressors. The unit capacity of the CU amounts to 9,000 m3 / h; gas flow is controlled by a special two-level regulation system.



Process equipment provides a necessary compression ratio: the APG inlet pressure is 0.4 MPa, the outlet pressure is 2.6 MPa. The purification of gas entering the compressors (two-step removal of liquid fractions and solid particles) is carried out by highly efficient coalescing filters-scrubbers with automatic drainage system.

The delivery lines of CUs are equipped with a shell-and-tube heat exchanger (with a built-in separator and a condensate collector), which cools the compressed APG, removes the resulting condensate and maintains the calculated temperature of the gas fuel set by the turbines manufacturer and design requirements.

BCSs are fully automated. Local control systems of compressor units are tied by a group regulation algorithm and integrated with the upper level of the APCS of facilities. The joint ACS of each compressor station provides remote control of equipment, automatic protections and alarm; monitors the process parameters and gas pollution in the machine room of the BCS; handles the parameters of the workflows and emergency events; issues information to the operator panel.



Operation mode of gas booster units as part of the power plants is continuous, with scheduled shutdowns for maintenance.
