COMSOL® models have been developed for teaching gas absorption fundamentals. Model results are compared to environmentally significant experimental results for removing CO₂ and SO₂ from air using water as solvent. For concentrated gas mixtures, the models are shown to be equivalent to but easier to use than the traditional graphical integration method and to a solution method developed with MATLAB®.

A more detailed model has been developed that explicitly uses the two-film theory of mass transfer and illustrates the resistance to mass transfer due to the liquid and gas films and the physical significance of the mass transfer coefficient.
