在C2分离器底部以免除丙烯制冷装置的热泵
摘要：
一种冷却乙烯排出气的方法，包括以下步骤：从C2分离器排出液态乙烷；在减压阀中降低排出的液态乙烷的压力以产生冷却的液态乙烷；在汽化器中用所述冷却的液态乙烷冷却所述乙烯排出气，所述冷却的液态乙烷以乙烷蒸汽的形式离开所述汽化器；在热泵中加压所述乙烷蒸汽以产生经加热的蒸汽乙烷；以及使所述经加热的蒸汽乙烷返回至所述C2分离器。所述乙烯排出气可以来自于乙烯制冷压缩机。
摘要（英）：

A method of cooling the ethylene exhaust gas comprising the steps of: discharging the liquid ethane from the C2 separator; reducing the pressure of the discharged liquid ethane in the pressure reducing valve to produce cooled liquid ethane; and in the vaporizer, Liquid ethane to cool said ethylene exhaust gas, said cooled liquid ethane leaving said vaporizer in the form of ethane vapor; pressurizing said ethane vapor in a heat pump to produce heated steam ethane; and The heated steam ethane is returned to the C2 separator. The ethylene exhaust gas may be from an ethylene refrigeration compressor.
