The process of CO2 absorbed in a hollow fiber membrane absorber was studied. For the non-wetted mode
the mathematical model of mass transfer in the membrane absorber was derived. The solution method for nonlinear partial differential equations was given by using T-model difference scheme. For water
NaOH
monoethanolamines (MEA) and 2-amino-2 -methyl-1-propanol (AMP) as absorbents
the process of CO2 absorbed in hollow fiber membrane absorber was simulated. In addition
the absorption of CO2by an aqueous mixture of AMP-MEA was also investigated. For CO2 absorbed into 0.6 mol8226;L-1 NaOH solution
the result of simulation agreed well with the experimental data.
