“…When a distillation unit is combined with a single‐stage membrane unit, the separation ratios in this hybrid system are affected by the membrane characteristics. The membrane unit can be configured with the distillation unit in three ways (Figure ), considering the hybrid system configurations mentioned in several reports …”

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.

“…A recent investigation also mentioned the butadiene separation from a C4-mixture [2]. Most previous concepts aimed to debottleneck C2-splitter or C3-splitter by installing a parallel membrane module with a distillation column [2,3,9,16,17].…”

“…It is generally accepted that membrane processes not only offer significant energy savings compared to more conventional processes 1,2 (for example, distillation, absorption, and so on), but also reduce the raw material inputs such that they do not require large inventories of hazardous chemicals. The use of membranes in separation processes has grown dramatically over the last 10 years, with an annual growth rate of aroundnow being seen primarily because of their excellent thermal and mechanical stability properties.…”
