FIELD: oil and gas industry.
SUBSTANCE: complex for liquefaction, storage and offloading of natural gas includes the following stages united by direct and reverse communications, parametres of which are set in accordance with impurity contance in raw natural gas, as well as with region climate conditions and topography: strage for separating and measuring natural gas, stage for purifying natural gas from mercury and methanol, stage for purifying natural gas from acidic impurities, stage for drying and purifying natural gas from mercaptans, stage for purifying natural gas from heavy hydrocarbons C5 and above, stage for liquefying natural gas, stage for storing and compounding refrigerant components, stage for compressing refrigerant, stage for storaging liquefied natural gas, stage for offloading liquefied natural, stage for compressing stripping gas compressor and stage for purifying stable condensate from mercaptans.
EFFECT: invention solves the problem for developing a system for transporting natural gas from the field to the consumer with intermediate processing of natural gas, which involves extraction of gas and petrochemicals from valuable raw materials and regenerated reagents, while minimizing the losses of natural gas to the environment.
