FIELD: low-temperature equipment, particularly cryogenic devices to process natural gas into liquid methane and to obtain pure gases in gas-separation devices.
SUBSTANCE: device has cylindrical body with inlet and outlet pipes, regenerable cylindrical multiply filtering member coaxially arranged inside cylindrical body, connection pipe to discharge contaminant effluent and flow resistance gauge. Connection pipe for pure gas supplying is connected to outlet pipe. Regenerable cylindrical multiply filtering member is made of metal and has fine porous filtering layer. Additional case having vacuum shield thermal insulation is coaxially arranged outside the cylindrical body.
EFFECT: increased efficiency of cryogenic gas purification.
