Dynamic Modeling of CO2 Absorption Process Using Hollow-Fiber Membrane Contactor in MEA Solution

In this work, a comprehensive mathematical model was developed in order to evaluate the CO2 capture process microporous polypropylene hollow-fiber membrane countercurrent contactor, using monoethanolamine (MEA) as chemical solvent. terms of absorption, showed excellent agreement with experimental data published literature for wide range operating conditions (R2 > 0.96), 1–2.7 L/min gas flow rates and 10–30 L/h liquid rates. Based on model, effects rate, aqueous absorbents’ rate also inlet concentration removal efficiency were determined. The % increased while increasing MEA solution rate; 81% removed at high rate. decreased residence time contactors when lower, reaching 97% 1 L?min?1. However, effect more pronounced Additionally, influence momentous operational parameters such number fibers module length separation evaluated. On basis, used flexible operation scenario (with variation conditions) predict (liquid gaseous flows, composition streams, mass transfer area, coefficient, etc.).
