Chemical engineering simulation of membrane separation coupled with reactions
Thread Content
I would appreciate some guidance from experts: what is the Aspen template or design method for coupling membrane dehydration with esterification reactions?
I think simulation software is just a tool; it merely provides computational integration for individual unit operations, while the specific process procedures are determined by humans. Its advantage lies in traditional thermodynamic equations, rather than dynamics and molecular thermodynamics. The simulation of the esterification reaction is good, but for membrane separation systems, I believe that only the membrane separation coefficients and fluxes are artificially specified. Moreover, the membrane separation coefficient and flux vary significantly depending on different feed concentrations and compositions, as well as the chemical environment of the system; therefore, I believe that Aspen is not yet fully developed for membrane separation tasks. The above are purely personal opinions; they may not be correct – just random talk!
