Abstract:

This article introduces the characteristics of FCC regeneration flue gas and the influence of high gravity technology on the CO2 removal rate of amine absorption method. Compared with other organic amine absorbents, the MDEA method has more practical applications, and the CO2 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 CO2 removal rate of MDEA method is about 70.45%; after the introduction of high gravity technology, the CO2 removal rate can reach 90% at different CO2 concentrations; with the increase of centrifugal acceleration, the CO2 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.

Key words: FCC, regeneration flue gas, amine absorption method, CO2 capture, MDEA, high gravity rotating bed, removal rate

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CO2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CO2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CO2脱除率约为70.45%;引进超重力技术后，在不同的CO2初始浓度下CO2脱除率均可达到90%;随着离心加速度的提高，CO2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。
