FIELD: cryogenic engineering.
SUBSTANCE: device comprises source of natural gas, pipeline for supplying natural gas from the source of natural gas provided with a valve, device for reducing gas pressure, tank for low-pressure gas, Stirling cryogenic machine, and pipeline for discharging the liquefied gas. The discharging pipeline connects the condenser of the Stirling cryogenic machine with the tank for storing liquefied gas. The freezer of the admixtures in the natural gas is connected with the condenser of the cryogenic machine through the pipeline for purified dry natural gas. The by-pass provided with a check valve connects the gas space of the tank for storing liquefied natural gas with the condenser of the cryogenic machine through the freezer. The pipeline for discharging liquefied gas passes through the freezer.
EFFECT: reduced sizes and mass and expanded functional capabilities.
