FIELD: gas processing.
SUBSTANCE: invention relates to the regasification of liquefied natural gas (LNG), where Rankine cycles are used for regasification of LNG. The system includes an LNG tank, a cryogenic pump for pumping LNG through heat exchangers located in gas ducts and receiving heat from flue gases leaving the boiler, a turbo expander with an electric generator on one shaft. The flue gas pipeline is made in the form of several flues: a central and two additional gas ducts departing from the central one, in which heat exchangers are installed. Additional ducts with heat exchangers installed in them are connected to each other by means of a rotary gas duct with a separation device for condensate removal. The gas ducts are equipped with adjusting gates.
EFFECT: invention makes it possible to increase the efficiency of regasification of liquefied natural gas, as well as the overall efficiency of using the discharged heat of the exhaust gases of the boiler room boilers and LNG cold energy.
