Separating the CO 2 from the associated gas is the key to improving resource utilization and reducing environmental pollution. It is confirmed that the MDEA-MEA mixture is used as the absorption liquid according to the composition and pressure of the associated gas in the current oil field. Taking a domestic CO 2 flooding produced liquid as the research object. The separation process was simulated by Aspen HYSYS software, and compared with the actual absorption and separation situation. According to simulation calculation, for the associated gas with a CO 2 proportion of 30%, the separation rate of CO 2 by the system can reach 98.32%, and the purity of CO 2 is 99.28%. Furthermore, it provides a technical example for rational use of simulation calculation to estimate the efficiency of CO 2 separation by mixed amine absorption method in engineering.
