Abstract: “Membrane processes are, together with cryogeny, absorption and adsorption, a key technology for gas separation applications. For simulation purposes, a constant membrane permeability hypothesis is most often assumed for each gas compound, for sake of simplicity. In this study, the incidence of variable (i.e. pressure dependent) permeability of gases or vapors through dense polymeric membranes on module separation performances or design is investigated through a simulation study. A dedicated computer software (MEMSIC) including multicomponent mixtures computations and extendable to Process System Engineering (PSE) softwares through a CAPE OPEN tool is described. The modelling approach offers, for the first time, a rigorous computation of transmembrane fluxes based on different solution-diffusion models (dual mode, Flory Huggins, ENSIC) for a set of absolute upstream and downstream pressure…”
