Significance of gas velocity change during the transport of CO2 through hollow fiber membrane contactors
TL;DR: In this article, a comprehensive 2D mathematical model was developed for the physical and chemical absorption of CO 2 from natural gas containing high percentage of CO2. Unlike previous mathematical models, the model considers change in the axial gas velocity as CO 2 is being absorbed from the gas mixture.
