摘要
CO2化学吸收法吸收剂及其降解产物的逃逸会导致吸收剂成本变高以及胺类排放污染大气,带来运行成本增加和环境污染.本文主要介绍了胺逃逸类型、原理及逃逸控制方法.文中指出:水洗和传统除雾器为目前常用的控制方法,可高效率去除气体和物理夹带逃逸,但气溶胶由于粒径小、逃逸量大带来的问题还未得到很好的解决.目前较为常用的控制方法有加大分离设备、控制运行参数、添加助剂、中间冷却法等方法,未来的发展趋势仍将放在物理方法上,如急冷、高频电场等,在不改变前期反应条件的基础上,在吸收塔或水洗塔后对逃逸气体进行控制.在兼顾CO2吸收法捕集效率的前提下提高经济效益和环境效益,为工业发展提供技术支持.
Abstract
The escape of CO2 chemical absorption absorbent and its degradation products will lead to the high cost of absorbent,and the emission of amines will pollute the atmosphere,which will increase the operating cost and pollute the environment.This paper mainly introduces the types,principles and control methods of amine escape.Water washing and traditional demister are commonly used control methods at present,which can effectively remove gas and physical entrainment escape,but aerosol escape has not been well solved because of its small particle size and large escape volume.At present,the commonly used control methods include increasing separation equipment,controlling operation parameters,adding additives,and intermediate cooling.The future development trend is to still put physical methods,such as quenching,high-frequency electric field and other methods,to control the escaping gas after the absorption tower or water washing tower without changing the previous reaction conditions.On the premise of taking into account the capture efficiency of CO2 absorption method,the economic and environmental benefits will be improved and technical support will be provided for industrial development.
