FIELD: gas industry.
SUBSTANCE: invention relates to equipment for regasification of liquefied natural gas with production of liquefied hydrocarbon gases; it can be used in the gas industry. An installation is proposed, including pumps of medium and high pressure 1 and 2, demethanizer 3, and deethanizer 4 with a heated bottom, heater 5 with outer heat source 6, and expander-compressor machine 7. During the operation of installation, LNG supplied by pump 1 is separated into two parts, the first of which is directed to column 3, and the second one supplied by pump 2 is heated in columns 3 and 4, heater 5, using an intermediate circulating heat carrier supplied from source 6, reduced in the expander of machine 7, and directed to column 3 as steam irrigation. From the top of column 3, deethanized natural gas is removed, compressed in the compressor of machine 7, and directed to a gas pipeline. From the bottom of column 3, ethane-containing condensate is directed to deethanizer 4, where it is separated into an ethane fraction and LPG.
EFFECT: increase in the yield of an ethane fraction.
