Abstract

Abstract: Monoethanolamine(MEA),diethanolamine(DEA)and N-methyldiethanolamine(MDEA) were used to investigate their infiltration to polypropylene(PP)hollow fiber membranes by contact angle test and soaking test. Mass transfer resistance and the CO₂ removal rate were determined by the absorption test at different membrane wetting levels. The results showed that,the infiltration of the membrane increased with the increase of absorbents concentration,the infiltration increased further after the absorption of CO₂,After the concentration of 30% tends to be stable,at this time,the ranking of the infiltration degree:MDEA > DEA > MEA. In the three stages of the wetting film with MEA、DEA and MDEA,the wetting rate of the accelerated wetting stage was 44 times,25 times and 20 times higher than that of the initial wetting stage,respectively. Membrane mass transfer resistance increased by 6 times,11 times and 13times,respectively,and become control resistance of the system,the removal rate also declined thereafter,with declines of 24.2%,29.9% and 37.2%,respectively. The infiltration of amine absorbents has a significant effect on CO₂ removal performance with membrane gas absorption method.

摘要： 采用接触角试验和浸泡试验，测定了一乙醇胺（MEA）、二乙醇胺（DEA）和N-甲基二乙醇胺（MDEA）共3种吸收液对聚丙烯（PP）中空纤维膜的浸润性和润湿速率，并通过吸收试验确定了不同润湿程度下的传质阻力和CO₂脱除率。结果发现，吸收液对膜浸润性随着浓度的增加而增大，吸收CO₂后的吸收富液对膜浸润性会进一步增大，质量分数达到30%以后趋于平稳，此时浸润性大小依次为：MDEA > DEA > MEA。在MEA、DEA和MDEA润湿膜的3个阶段中，加速润湿阶段的润湿速率较初始润湿阶段分别提高44倍、25倍和20倍。膜相传质阻力在膜润湿加速后分别增加6倍、11倍和13倍，并成为传质控制因素。相应的，CO₂脱除率也出现下降，降幅分别为24.2%、29.9%和37.2%。吸收液浸润性对膜吸收法脱除CO₂性能的影响显著。
