Solution of the linearized equations of multicomponent mass transfer with chemical reaction by matrix methods

Abstract

The linearized equations of multicomponent mass transfer with chemical reaction are solved by matrix methods fora film model. The molar flux of each component at the film boundary and the concentration profile of each component across the film are calculated. The general solution obtained is also applied to two variations. of the mass transfer problem; the case when there is no reaction and the case when there is reaction but no convection. The method of solution is applied to the cyclopropane-propene-argon-neon and the iodine-hydrogen-hydrogen iodideargon quaternary reacting sys·tems. The homogeneous reactions in both cases occur isothermally in the gas phase. The ·results of the computations show that as the reaction rates increase or as the diffusive fluxes decrease, the enhancement factors increase.The lower fluxes obtained in the cases when the convective terms are equated to zero snow thai the convective mechanism of mass transfer is just as important as the diffusive and reactive mechanisms in the film.
