“…Modelling and simulation of the membrane process are necessary to predict the membrane separation performance, and to provide valuable information on the separation process design, operation, and economic evaluation. Weller and Steiner, [41][42] who performed the earliest work to address the mathematical modelling of membrane gas separations, studied the membrane gas permeation in a single-stage module for a binary mixture focusing on permeation analysis, permeator simulation, module design, and economic evaluation using various structures and forms. Subsequently, a number of researchers have developed various mathematical models and calculation techniques for both symmetric and high-flux asymmetric membranes with different flow patterns and module configurations.…”

This article investigates the separation performance and energy efficiency of multistage membrane and hybrid processes for the separation of propane/propylene mixtures compared with the conventional distillation process. To satisfy the separation objective of 0.996 mol/mol (99.6 mol%) C3H6 purity and 97 % C3H6 separation recovery ratio, a detailed parametric study for the multistage membrane and hybrid process systems was described. For this purpose, the effects of operating conditions and process configurations on separation performance have been evaluated using a counter‐current flow model. The numerical model using a single‐stage membrane was validated with published experimental data for the membrane system, and the model was then applied to multistage membrane and hybrid processes. The optimum variables that satisfy the targeted purity and recovery ratio were examined using the multistage membrane at a given selectivity and pressure ratio. The energy consumption of several hybrid configurations for the separation of propane/propylene mixtures was investigated with conventional distillation.
