PURPOSE: A gas precooling system for natural gas liquefaction using an absorption refrigerator is provided to reduce the consumption of electrical energy by precooling natural gas using an evaporator and liquefying the cooled natural gas. CONSTITUTION: A gas precooling system for natural gas liquefaction using an absorption refrigerator includes regenerator(110), a condenser(120), an evaporator(130), and an absorber(140). The regenerator heats a mixture(142) in which an absorbing material(141) and an absorbing refrigerant(131) are mixed and separates the refrigerant and absorbing material. The condenser condenses the absorbing refrigerant using cooling water(151). The evaporator evaporates the absorbing refrigerant under low pressure and absorbs heat energy. The absorber generates a mixture and maintains the temperature suitable for the production reaction of a mixture using cooling water. |
