GAS PRECOOLING EQUIPMENT FOR NATURAL GAS LIQUEFACTION USING ABSORPTION REFRIGERATION

摘要

Simultaneously cooled natural gas will aside be compressed to the absorption refrigerating machine cooling source in natural gas liquefaction system of the invention in the absorption refrigerating machine of cooled natural gas reserves, using through the configuration of the gas pre-cooler for natural gas liquefaction using the pre- cold absorbent of absorption refrigerating machine according to the present invention (141) and absorption refrigerating machine refrigerant 131 for the natural gas involved in gas pre-cooler is to absorb, and passes through separate absorbent agent (141) (110) extraction by the deep cool device refrigerant 131 of heating blended mixture 142 and regenerator; By the player 110 of a condenser, it is used to agglomerate coolant 151 in separated gas phase to absorption refrigerating machine refrigerant 131 from 120; Condenser 120, refrigerant, by absorbing absorption refrigerating machine (131) of the thermal energy from external (130) from low pressure evaporator evaporation concentrated solution; Evaporator 130 absorb absorption refrigerating machine refrigerant 131 to absorber (141) to produce mixture (142), but replace cooling water appropriate maintain reaction mixture temperature produce 142 (151) and using mixture cooling absorber be evaporated with producing in one 142 (140); It carries out including: that evaporator 130 is characterized in that absorbing thermal energy from the cooling object 160 on the periphery by evaporator (130).
