Mathematical Modeling and Numerical Simulation of CO2 Removal by Using Hollow Fiber Membrane Contactors
TL;DR: In this paper, a mathematical model is proposed for CO2 separation from N2/CO2 mixture using a hollow fiber membrane contactor by various absorbents, assuming the contactor assumed as nonwetted membrane; radial and axial diffusions were also considered in the model development.
