FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to liquefaction of natural gas (LNG). LNG production system includes liquefier (14), which cools and liquefies natural gas by means of coolant supplied from refrigerating unit, storage tank (16) for LNG storage, line (L6) for movement of liquefied natural gas from LNG tank (16), LNG carrier (18), by means of which liquefied natural gas passing through line (L6) is transported, recondenser (17), which recondenses the stripping gas generated by the heat transferred to the liquefied natural gas, by means of a coolant supplied from refrigeration unit (15), and return line (A4), which supplies liquefied natural gas which has been liquefied, into LNG tank (16) from recondensator (17).
EFFECT: technical result is enabling possibility of recondensing of the gas without using the exhaust gas compressor and regardless of the LNG liquefaction stage.
