FIELD: gas industry.
SUBSTANCE: natural gas liquefaction system is mounted at the compressor station of the main gas pipeline and connected to a DN 200 gas pipeline running from the outlet collector of the dust collectors to the auxiliary block box. In the natural gas liquefaction system, adsorption-type natural gas drying and purification units, a heat exchange unit consisting of three preliminary heat exchangers for gas cooling, a turbine module consisting of injection and expansion turbines mounted on one working shaft, and an electric generator, the main cryogenic module were installed , adjustable chokes of the first and second stages, a separation unit consisting of a main and receiving separators, a weighing unit for liquefied natural gas, a unit for storing and dispensing liquefied natural gas, an ejector for supplying natural gas into the gas pipeline to receive the block box for the auxiliary needs of the compressor station, pipeline and reinforcement strapping.
EFFECT: development of an effective natural gas liquefaction system in the conditions of a compressor station, improved fire safety.
