摘　　要：以有机胺为吸收剂的化学吸收法具有吸收容量大、吸收速率快、CO_(2)捕集效率高等优点,但传统热解吸再生面临着能量利用率低、氨逃逸、吸收剂氧化降解等难题严重影响其发展,有必要对当前有机胺富液解吸再生工艺的研究进行改进与优化,以降低能耗与损耗。本文介绍了热解吸耦合催化解吸再生工艺和热解吸耦合膜解吸再生工艺,并对新兴的微波解吸再生、矿化再生、电化学介导胺解吸再生工艺方法的基本原理和研究现状进行总结,对比分析了各工艺的优缺点和适用的有机胺类型。选择合适的有机胺富液解吸工艺有利于降低解吸能耗:催化解吸适用于大多有机胺吸收剂;膜解吸适用于单胺类吸收剂;微波解吸再生适用于极性基团较多、介电常数大的有机胺;矿化再生适用于叔胺类吸收剂;电化学介导胺解吸再生适用于多胺类吸收剂。The chemical absorption method using organic amine as absorbent has the advantages of large absorption capacity,fast absorption rate,high CO_(2)capture efficiency,etc.,but its higher regeneration thermal energy consumption and other problems seriously affect its development.The traditional thermal desorption regeneration faces problems such as low energy utilization,ammonia escape,oxidative degradation of absorber,etc.It is necessary to improve and optimize the current research on organic amine-rich liquid desorption and regeneration process in order to reduce energy consumption and loss.This paper introduced the catalytic desorption and regeneration and membrane desorption and regeneration processes based on thermal desorption,and summarized the basic principles and current research status of the emerging microwave desorption and regeneration,mineralization regeneration and electrochemistry-mediated amine desorption and regeneration processes,and compared and analyzed the advantages and disadvantages of the various processes and the types of organic amines to which they were applicable.The selection of suitable organic amine rich liquid desorption process was conducive to reducing the energy consumption of desorption.The catalytic desorption was suitable for most organic amine absorbents,the membrane desorption was suitable for monoamine absorbents,the microwave desorption and regeneration was suitable for organic amines with more polar groups and large dielectric constants,while the mineralization regeneration was suitable for tertiary amine absorbents,and electrochemically-mediated amine desorption and regeneration was suitable for polyamine absorbents.
