燃煤烟气中CO_2膜吸收分离技术的膜浸润特性述评
|
摘要
膜吸收法是分离燃煤烟气CO_2的主要工艺之一,膜润湿造成的膜阻力增加以及膜表面形态改变是膜吸收法研究中遇到的主要问题,阻碍了膜吸收法的广泛应用。本文在膜吸收法的基本原理基础上,阐述了影响膜润湿的因素(吸收剂种类、吸收液浓度、温度、液相压力和流速)以及膜特性因素(膜材料和膜结构)的最新进展,详细分析了膜与吸收剂之间的兼容关系,确定孔润湿是制约膜组件长期稳定运行的关键因素。最后提出了未来缓解膜润湿方面的主要研究方向:优化操作条件、开发新型性价比高的吸收剂和膜材料以及通过进行膜的表面改性等手段来改善膜和吸收剂的兼容性,提高膜接触器长时间运行的稳定性以及进一步细致探究如何恢复膜组件的性能,从而提高重复利用率。
Membrane absorption method was one of the main processes for separating CO_2 from coalfired flue gas. The increase of membrane resistance caused by membrane wetting and the change of membrane surface morphology were the main problems encountered in membrane absorption research,which hindered the wide application of membrane absorption method. Based on the basic principles of membrane absorption, the factors affecting membrane wetting(type of absorbent, concentration of absorbent, temperature, liquid phase pressure and flow rate) and membrane properties(membrane material and membrane structure) were described. The compatibility between membrane and absorbent was analyzed in detail. It was determined that pore wettability was the key factor restricting the long-term stable operation of membrane module. Finally, it was pointed out the main research direction for mitigating membrane wetting in the future as follows: optimizing operating conditions, developing new cost-effective absorbents, membrane materials and surface modification to improve the compatibility of membrane and absorbent, improving the stability of long-term operation of membrane contactors, and further exploring how to restore the performance of membrane components, so as to improve the reusability rate.
