摘　　要：克拉玛依石化公司采用催化裂化装置吸收稳定系统和气体分馏装置联合优化工艺对装置进行优化调整,通过优化催化裂化吸收稳定系统的操作条件,将液化气中的乙烷含量控制在0.5%左右;并停开气体分馏装置脱乙烷塔,停止排放乙烷气,以减少丙烯损失。运行期间丙烯产率提高了1.69个百分点,丙烯回收率提高了6.79个百分点,而且降低了装置能源消耗,取得了显著的经济效益。In order to reduce the loss of propylene, an integrative optimization of FCC absorption-stabilization system and gas fractionation device was conducted at Karamay Petrochemical Company. The ethane content in LPG was kept below 0.5% by optimizing the operation conditions of FCC absorption and stabilization system, thus the de-ethane tower could be cut off from the gas fractionation device to avoid the loss of propylene from the discharged ethane stream. The running results showed that the propylene yield increased 1. 69 percentage points, the propylene recovery rate increased 6.79 percentage points and the energy consumption was lowered.
