✦ Synopsis

ONDA, Sada, Kobayashi and Fujine [l] have considered a problem of simultaneous absorption and reaction of two gases represented by the following scheme:

Here A and B are the two gases being absorbed and C is the liquid phase reactant. The product formed in the first reaction, S, reacts with the gas B to regenerate the reactant C. The solution to this problem given by the above authors is applicable to reactions obeying a fast general order kinetic law. The solution to the problem for the case, where the reaction between .4 and C is instantaneous has not been considered. For this case, the concentration of the liquid phase reactant C drops to zero at some point in the liquid film and this requires the problem to be considered separately. It is the purpose of this note to bring out some special features of the problem enunciated above, for the case when the reaction between A and C is instantaneous.

In the following discussion, the reactions (i) and (ii) are assumed to be irreversible and second order and it is assumed that there is no gas side resistance to the transport of A and
