โœฆ Synopsis


The problem of simultaneous absorption of two gases accompanied by reversible instantaneous chemical reactions is considered. Analytical equations are derived for the rates of absorption of the two gases. The solution is valid when the diffusivities of all the 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.

Film and penetration theory solutions are presented for gas absorption accompanied by a two-step chemical reaction involving a transient intermediate species. For the case of equal diffusivities, the two theories agree with each other within 6 per cent. When the intermediate species is relatively lo
