Modelling of Accelerated CO2 Absorption Using an Enzyme in a Hollow Fiber Membrane Contactor

Carbon dioxide (CO₂) is widely recognized as the main cause of climate change affecting our planet. In recent years, the concentration of CO₂ in the atmosphere has increased significantly due to the intensive combustion of fossil fuels. This study is devoted to the simulation of the 1D case of the CO₂ capture process by aqueous Potassium carbonate K₂CO₃ as chemical solvent promoted with BCa (Bovine carbonic anhydrase), using a membrane contactor in the counter current case. The system of partial differential equations resulting from the modelling were solved using MATLAB's PDEPE function. We also carried out a parametric analysis to see the impact of various parameters on the CO₂ capture process. Among these parameters, we studied the influence of solvent concentration, gas velocity and liquid velocity. The results show that 13% increase (74% to 87%) on CO₂ capture while the increase of solvent concentration from 20 to 50 (mol/m3), also for gas and liquid velocity from 0.001 to 0.05 and 0.006 to 0.05 (m/s) we have 52% and 3 % increase of CO₂ capture respectively.at final the Enzyme had an effect of average 7% of absorption of CO₂.
