Abstract

A mathematical model was developed for the absorption of gas in liquid considering diffusion and a reaction of a gas through a non-isothermal, exothermic, irreversible first order reaction. The model consists of a set of coupled partial differential equations for heat and mass transfer, which were solved using a finite-difference backward implicit scheme. Parameters like the Thiele modulus, the Arrhenius factor and the Biot number for mass transfer of different kinetic mechanisms were optimized using a genetic algorithm. The utility of this model is illustrated by applying it to the absorption of chlorine gas into n-decane solution. A comparison of this model with literature has also been done.
