摘　　要：介绍了流化催化裂化(FCC)再生烟气特点以及超重力技术对胺液吸收法CO_(2)脱除率的影响。与其他有机胺液吸收剂相比,N-甲基二乙醇胺(MDEA)实际应用较多,选择MDEA法所得到的CO_(2)脱除率等相关数据更具有代表性。对MDEA法的模拟计算结果显示:MDEA法CO_(2)脱除率约为70.45%;引进超重力技术后,在不同的CO_(2)初始浓度下CO_(2)脱除率均可达到90%;随着离心加速度的提高,CO_(2)脱除率在达到峰值后基本保持不变。对FCC再生烟气胺液吸收法碳捕集技术发展方向进行了展望。This article introduces the characteristics of FCC regeneration flue gas and the influence of high gravity technology on the CO_(2)removal rate of amine absorption method.Compared with other organic amine absorbents,the MDEA method has more practical applications,and the CO_(2)removal rate and other related data obtained by choosing the MDEA method are more representative.The simulation calculation results of MDEA method show that the CO_(2)removal rate of MDEA method is about 70.45%;after the introduction of high gravity technology,the CO_(2)removal rate can reach 90%at different CO_(2)concentrations;with the increase of centrifugal acceleration,the CO_(2)removal rate remains basically unchanged after reaching the peak.The development direction of carbon capture technology by amine absorption method for FCC regeneration flue gas is prospected.
