Abstract

The capture of CO2 from flue gas and natural gas is essential for the sake of humanity. Aqueous potassium lysinate (LysK) is a suitable solvent utilized in the CO2 capturing process. Regeneration of the rich Lysk solution is crucial for process continuation and cost-effectiveness. In the present work, a two-dimensional mathematical model that considers both axial and radial diffusion are established to describe the CO2 elimination from rich potassium lysinate solution. The model describes the LysK regeneration process in a hollow fiber membrane contactor module. The modeling results showed that the carbon dioxide removal ratio is directly proportional to the amount of carbon dioxide present in the solution and the temperature of the solution. The increase in stripping temperature increases the percent CO2 released from rich solvent.
