FIELD: oil and gas industry.
SUBSTANCE: invention discloses a device comprising a storage tank, a compressor with a hydraulic piston and a gas-fed plant. Storage tank is configured to store liquefied gas therein. Compressor with hydraulic piston is located downstream of storage tank and in fluid communication with it and is configured to obtain stripping gas from reservoir for storage and compression of said gas. Gas-fed unit is located downstream of the compressor with the hydraulic piston and in connection with it by fluid medium and is made with possibility to obtain compressed gas from the compressor with the hydraulic piston. Preliminary compressor is configured to obtain stripping gas from reservoir for storage and increasing pressure of stripping gas to level of 200 kPa abs up to 2 MPa abs (from 2 bar abs to 20 bar abs). Preliminary compressor is located downstream of storage container and in fluid communication therewith and upstream of compressor with hydraulic piston and in connection with it by fluid medium.
EFFECT: technical result is removal of stripping gas and possibility of its use.
