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 can reduce the energy needed, the apparatus using a Rankine cycle system comprising; a first compression device(1), a first heat exchanger (2), an expansion device(3), a second heat exchanger (4), 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(6) that is coupled to the expansion device, wherein, at the second heat exchanger, a low-temperature liquefied natural gas 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 wherein, the low-temperature fluid is thereafter compressed at the second compression device to produce a low-temperature compressed fluid. |
