摘要：

In this study, the process of CO2 removal by a hollow fiber membrane contactor (HFMC) is investigated numerically. In the HFMC, the absorbent solution (potassium lysine solution) flows through the fiber bundle, while the air flows on the shell side. The hollow fiber membrane contactor consists of staggered cylindrical fiber tubes with equal longitudinal and horizontal pitches. This study investigates the flow and mass transfer process of air and absorbing liquid inside the HFMC systematically by computational fluid dynamics methodology. After experimental validation, the model is used to calculate the friction factors and Sherwood numbers for various operating conditions on the shell side. Besides, the new correlations for predicting friction factor and Sherwood number are proposed as reference to the designs of membrane modules. This work is crucial for simplifying performance evaluation and scale-up design for the membrane module. © 2025 Science Press. All rights reserved.
