FIELD: gas industry.
SUBSTANCE: invention relates to the main gas transport, particularly to compressor stations of underground gas storages. Device for compression of natural gas includes a centrifugal gas blower consisting of two compression sections arranged on the same shaft in a common housing, connected to the shaft of a driven gas turbine engine, herewith the process connections of the device is made with the possibility of switching the compression sections by means of stop valves to ensure series and parallel operation modes of the blower sections, the device also has three control shutoff valves, a filter-separator, gas air cooling devices.
EFFECT: higher reliability and efficiency of the device during the complete period of pumping into the underground gas storage in a wide range of variation of process parameters, as well as reduction of equipment.
