“…It should be noted that the selection of solvent for use in HFMCs is an important challenge. One of the first models for CO 2 absorption by PC solution in HFMCs was developed by Lee et al (2001) which was used to find the optimal absorbent flow rate and the effects of some parameters. The model was not validated with the experimental data.…”

Particularities of Membrane Gas Separation Under Unsteady State Conditions

“…are the only volatile species; a negligible change in the liquid phase volume during absorption of volatile components; concentration of volatile components in molecular form in the membrane and the liquid phase obeying Henry's law. The approach of CO 2 interaction with aqueous potassium carbonate can be found in numerous studies (Cents et al, 2005;Chen et al, 1999;Danckwerts & Sharma, 1966;Dindore et al, 2005;Lee et al, 2001;Morales-Cabrera et al, 2005;Otto & Quinn, 1971;Pohorecki & Kucharski, 1991;Suchdeo & Schultz 1974;Ward & Robb, 1967 Theoretical and experimental dependencies are almost identical for the LM with distilled water (Fig. 18) and the time of unsteady CO 2 transfer is about 30 seconds.…”

Hollow Fiber Membrane Contactors for Post-Combustion CO2Capture: A Scale-Up Study from Laboratory to Pilot Plant

“…The earlier models solve the mass balances in two dimensions in order to compare the radial and axial concentration profiles at different gas flow rates, liquid flow rates and temperatures [17,18] and also with varying solvents [19,20]. More recent work has looked at the transient behavior of gas absorption into a liquid [21], predictions using computational fluid dynamics [22] and effects of the wetting behavior of the membrane [23][24][25].…”
