摘要
An apparatus and a method for cooling and compressing a fluid to produce a low-temperature compressed fluid that can efficiently use the cold of LNG and reduce the energy needed, the apparatus using a Rankine cycle system having a first compression device, a first heat exchanger, an expansion device, a second heat exchanger, and a first flow passageway for guiding the heat transfer medium from the second heat exchanger to the first compression device; and at least one second compression device that is coupled to the expansion device, wherein at the second heat exchanger, a low-temperature LNG and the heat transfer medium undergo heat transfer, wherein at the first heat exchanger, a fed material gas and the heat transfer medium undergo heat transfer to produce a low-temperature fluid from the material gas, and the low-temperature fluid is compressed at the second compression device to produce a low-temperature compressed fluid.
