Polyvinyl Chloride/Acrylonitrile Butadiene Styrene (PVC/ABS) and Nanocomposite (CAU-10-H) Composite Membrane for Separation of C2H6 from CH4

Abstract

In the research, composite membranes derived from Acrylonitrile Butadiene Styrene (ABS), Polyvinyl Chloride (PVC) were prepared with 30 wt%. In the next step, adding 0.125, 0.250, and 0.50 wt% of nanocomposite (CAU-10-H) to ABS/PVC was performed. All of the polymeric and nanocomposite membranes were fabricated by the solvent casting method using dimethylacetamide as a solvent. The performance of the prepared membranes was evaluated for methane (CH₄) and ethane (C₂H₆) at feed pressures of 2.5, 3.0, and 3.5 bar at a temperature of 35 °C. Results showed that in most cases, increasing the percentage of ABS and PVC led to an increase in the permeability of CH₄ and C₂H₆.
