摘要

Abstract A mass transfer model was developed to capture CO 2 from a gas mixture in hollow fibre membrane contactors under laminar flow conditions. The axial and radial diffusions through membrane and convection in tube and shell sides with chemical reaction were investigated. COMSOL software was used to numerically solve a system of non-linear equations with boundary conditions by use of the finite element method. Three different amine solutions of monoethanolamine (MEA), diethanolamine (DEA) and n -methyldiethanolamine (MDEA) were chosen as absorbent in lumen to consider the mass transfer rate of CO 2 and its removal efficiency. The modelling results were compared with experimental data available in the literature and a good agreement was observed. The CFD results revealed that MEA had the best performance for CO 2 removal as compared to DEA and MDEA under various operating conditions due to the different CO 2 loading factor of absorbents. Furthermore, efficiency of CO 2 removal was highly dependent on the absorbent concentration and flow rate, increasing of the gas flow rate caused a reduction in gas residence time in the shell and consequently declined CO 2 mass transfer. The modelling results showed the effect of absorbent concentration on the CO 2 mass transfer was improved due to availability of absorbent reactants at the gas-liquid interface.
