气体分馏装置的扩能改造

Expansion and Reconstruction of the Gas Fractionation Unit

随着催化装置扩量,液化气产量增加了,原10万吨/年气体分馏装置已经不能满足液化气加工需要,需进行扩能改造,经过对脱丙烷塔和精丙烯塔进行改造,以及部分机泵和换热器改造,达到13万吨/年处理量的需要。装置改造后运行平稳,达到设计指标。

For the output of LPG increased with the capacity of FCC expanded, the machining potent of gas fractiona- tion unit before which came to 100000 tons per year cannot meet the demand of LPG machining. Through the depropanizer tower and fine propylene tower were revamped, and parts of machine pump and heat exchanger reform, the unit can reach the machining potent come to 130000 tons per year. After reconstruction, the gas fractionation unit ran smoothly and met the design targets.
