A FILM MODEL-BASED APPROACH FOR SIMULATION OF MULTICOMPONENT REACTIVESEPARATION

A general approach to the design of multicomponent mass transfer accom panied by chemical reactions is presented. Both homogeneous and hetero geneous reactions in liquid phase, as well as their combination, have been studied and incorporated into the film model. Because of the mult icomponent nature of reactive separation, the mass transfer equations in the fluid phases are based on the Maxwell-Stefan approach. These eq uations are coupled by diffusional interactions in the gas (vapour) ph ase and by both diffusional and homogeneous chemical interactions in t he liquid phase. Heterogeneous reaction mechanism has been accounted f or by mass balance relationships. The solution obtained allows the det ermination of concentration profiles of the components along the conta cting apparatus.
