FIELD: gas industry.
SUBSTANCE: invention relates to the field of the gas industry, in particular to the compressor stations of the main gas pipeline. In the current scheme of the centrifugal compressor seal control system, including mechanical seals, gas preheater, oil accumulator, main and backup oil pumps seals, oil and gas differential pressure regulators, a gas separator, a float chamber and a surge alarm device, install a gas pipeline with pipeline fittings, a two-stage ejection installation consisting of two successively installed ejectors, and a pressure regulator, by means of which the gas-pumping unit of the compressor station with outlet pressure after the gas pressure regulator of 2.8 MPa is supplied to the gas separator line of the gas-turbine unit separated from the oil in the gas separator.
EFFECT: technical result of the invention is resource saving.
