Simultaneous absorption of two gases accompanied by reversible instantaneous chemical reactions

The problem of simultaneous absorption of two gases accompanied by reversible instantaneous chemical reactions is considered. Analytical equations are derived for the rates of absortion of the two gases. The solution is valid when the diffusivities of all species are assumed to be the same. The theoretical aspects of the problem of simultaneous absorption of hydrogen sulphide and carbon dioxide in amine solutions under equilibrium reaction conditions are also considered.
