FIELD: oil producing industry; boost pump-compressor machines.
SUBSTANCE: proposed boost pump-compressor plant includes positive displacement pump with compression chambers, drive, manifold with feed pump communicating with tank for working liquid, line to feed gas into compression chambers. Discharge piping communicates with compression chambers and consumer. Unit to separate working liquid is installed in discharge piping with liquid outlet device communicating with working liquid tank. Working liquid tank is made two-compartment, in form of intake tank for removed liquid and service tank for working liquid connected by pipeline with removed liquid flow meter installed in its lower part and with control and shutoff valves. Feed liquid flow meter is installed in manifold at feed outlet. Outlet of pipeline from receiving tank for removed liquid is arranged higher than base of intake tank and inlet into tank for working liquid, and outlet if pipeline from tank for working liquid is arranged higher than inlet of feed pump. Receiving tank for removed liquid can be furnished with pipeline to let out separated gas.
EFFECT: improved reliability and accuracy of determining volumetric content of liquid in pumped in gas-liquid mixture.
