FIELD: gas production industry.
SUBSTANCE: invention can be used to ensure the natural gas export. Natural gas liquefaction, storage and shipment complex includes the following units: natural gas separation and measurement unit, natural gas from mercury and methanol purification unit, natural gas from acidic impurities purification unit, natural gas dehydration and purification from mercaptans unit, natural gas liquefaction unit, refrigerant components storage and compounding unit, refrigerant compression unit, liquefied natural gas storage unit, liquefied natural gas shipment unit, stripping gas compression unit. After the stripping gas compression section compressor first stage stripping gas is sent in full for the zeolites regeneration to the natural gas dehydration and purification from mercaptans unit. Next, the saturated with moisture and impurities regeneration gas is used as fuel for compressors turbines in the refrigerant compression section, wherein, to increase its calorific value, the saturated with moisture and impurities regeneration gas is combined with the C5 and above heavy hydrocarbons after the natural gas liquefaction unit.
EFFECT: technical result is enabling energy saving and the system functioning variability during its operating conditions change.
