Simultaneous interphase mass transfer and a zero–order reaction is described by the film model of mass transfer. The analysis leads to the conclusion that three regimes of the process need to be considered. At low rates of absorption the reaction goes to completion in the film, and at higher rates it goes to completion in the bulk and proceeds there at zero apparent concentration of the reactant. At still higher rates of absorption the reaction does not go to completion and the reactant is present also in the bulk in appreciable concentration. Design procedures based on the results obtained are discussed for a well–mixed CSTR and for a column with con–tinuous change.
