Computational study on SO2 molecular separation applying novel EMISE ionic liquid and DMA aromatic amine solution inside microporous membranes

摘要

This research paper is aimed to deal with evaluating the separation efficiency of SO2 molecules applying novel 1-ethyl-3-methylimidazolium ethyl sulfate (EMISE) ionic liquid and dimethylaniline (DMA) aromatic amine solution inside a microporous membrane contactor (MMC). For this aim, a CFD-based mechanistic modeling and its associated simulation are developed. Simultaneously, the existed momentum and mass transfer equations are analyzed using the finite element procedure (FEP). The results demonstrated that the developed model's results are in acceptable agreement with the achieved literature data (experimental results) with average relative deviation (ARD) of lower than 5%. It is well understood that both EMISE and DMA solutions are significantly promising to separate SO2 molecules from an inlet SO2/Air gaseous mixture. A comparison of the results showed that EMISE ionic liquid has been able to separate 100% of inlet SO2 molecules while DMA possesses the ability to sequester about 98.8% of inlet SO2.
