深冷轻烃中CO2脱除工艺模拟分析

摘要

The removal of CO2 was designed by Aspen Plus software with the deep cooling light hydrocarbons from oil field as the raw material. The results showed that under the optimum operating pressure( 1.6 MPa), the stripping tower could remove 90％ CO2 (mass fraction) from the light hydrocarbons, the treated product could be used as cracking feedstock.%以油田深冷轻烃为原料,利用Aspen Plus工艺模拟软件,对原料脱除二氧化碳进行模拟设计.结果表明,采用提馏塔分离方案,在提馏塔最佳操作压力为1.6 MPa的条件下,可脱除深冷轻烃中质量分数为90%的二氧化碳,满足裂解装置对原料的要求.
