The unit is designed for preparation of gas, transferred by compressor stations of gas mains, for the purpose of its usage as:
- fuel gas for gas turbine start-up in gas-transfer turbo-compressor units (GPA);
- starting gas for gas turbine of GPA;
- impulse gas to control pneumatically-operated valves of compressor station (CS);
- fuel for compressor station own and residential settlement needs.
All equipment is manufactured as module article of full factory readiness. Local and remote measurement of operating parameters is provided for all plants.
The set of equipment comprises the following:
Gas cleaning plant is designed to clean gas from liquid drops and mechanical impurities at inlet of fuel, start and power gas treatment unit.
Gas measuring plant is designed to measure total amount of incoming to station gas as well as fuel and start gas amount.
Fuel gas heater incorporates a heater (electric or gas)with intermediate heat carrier, necessary for the operation of the compressor station during the start-up period.
Fuel gas treatment plants serve for reduction and keeping fuel gas specified pressure.
Power gas dehumidification and storage plant is designed for power gas dehumidification up to dew point by moisture of –55°С at working pressure, as well as for power gas accumulation in receiver and its distribution, as required, for control of compressor station pneumatically operated valves.
Local and remote measurement of operating parameters is provided for plants. The unit equipment control is performed by automatic control system of the station.
