FIELD: pipeline transportation of gas.
SUBSTANCE: invention relates to pipeline transportation of gas and is intended for preservation of bleed gas from a circuit of a compressor of a gas compressor unit (GCU) and dust collector (DC) during planned shutdown at compressor station (CS) before technical inspection or repair. Bleed gas pumping system at the compressor station includes the GCU compressor, pipeline valves, which cut off the GCU compressor circuit at shutdown, GCU plug pipeline, dust collector DC, ejector and discharge header of the compression station, according to the invention, the system additionally comprises a gas manifold with DC, pipeline valves shutting off DC, DC plug pipeline, bleed gas manifold, bleed gas discharge valve from the GCU compressor circuit to the bleed gas manifold, the active gas supply cock from the discharge header of the compressor station, which is installed on the active gas supply pipeline to the ejector, is also equipped with two pressure regulators arranged in front of the suction and in front of the ejector, and a filter-separator located in the fuel, starting and pulse gas preparation unit (FSPGPU), wherein the ejected gas discharge pipeline is connected to the inlet pipeline of the filter-separator.
EFFECT: preservation of the volume of the bled gas during the GCU shutdown and the compressor station dust collector repair on the single-line and multi-line gas pipelines due to its directing by means of one ejector to the inlet of the separator filter in the FSPGPU unit for further use of the stored gas for own needs, id est as fuel, starting, pulse gas, as well as for the needs of a residential community.
