In the current years, gas-liquid membrane contactors (GLMCs) have been introduced as a promising, versatile and easy-to-operate technology for mitigating the emission of major greenhouse contaminants (i.e., CO and HS) to the ecosystem. This paper tries to computationally study the role of membrane pores wettability on the removal performance of CO inside the HFMC. To fulfill this purpose, a mathematical model based on finite element procedure (FEP) has been employed to solve the momentum and mass transport equations in the partial-wetting (50% wetting of micropores) and non-wetting (0% wetting of micropores) modes of membrane during operation. Additionally, a comprehensive simulation was ensembled to predict the results. In this research, 2-amino-2-methyl-l-propanol (AMP) has been employed as a relatively novel alkanolamine absorbent to separate CO form CO/N mixture. Analysis of the results implied that the wetting of membrane micropores significantly deteriorated the removal efficiency due to the enhancing mass transfer resistance towards transferring CO (75% in the non-wetting mode > 8% considering 50% wetting of micropores).
近年来，气液膜接触器（GLMCs）作为一种有前景、多功能且易于操作的技术被引入，用于减少主要温室污染物（即一氧化碳和硫化氢）向生态系统的排放。本文试图通过计算研究膜孔润湿性对中空纤维膜接触器（HFMC）内一氧化碳去除性能的作用。为实现这一目的，采用了基于有限元程序（FEP）的数学模型来求解运行过程中膜在部分润湿（微孔50%润湿）和非润湿（微孔0%润湿）模式下的动量和质量传输方程。此外，还进行了全面的模拟以预测结果。在本研究中，2-氨基-2-甲基-1-丙醇（AMP）被用作一种相对新颖的链烷醇胺吸收剂，以从一氧化碳/氮气混合物中分离一氧化碳。结果分析表明，膜微孔的润湿显著降低了去除效率，这是由于传质阻力增加，不利于一氧化碳的传输（非润湿模式下为75%＞考虑微孔50%润湿时的8%）。
