INTERMEDIATE FLUID TYPE VAPORIZER

摘要

An intermediate medium type vaporizer is provided to easily vaporize liquefied natural gas by performing a heat exchange between natural gas and sea water in a count-current manner. An intermediate medium type vaporizer includes an intermediate medium vaporizer(120), a liquefied natural gas vaporizer(140), and a natural gas heater(160). The intermediate medium vaporizer vaporizes a liquefied intermediate medium through a heat exchange with a heat source fluid. The liquefied natural gas vaporizer vaporizes liquefied natural gas to low temperature natural gas through a heat exchange with the vaporized intermediate medium. The natural gas heater heats the low temperature natural gas through a heat exchange with the heat source fluid. The heat source fluid is separatedly supplied to the intermediate medium vaporizer and the natural gas heater.
