Ethylene Recovery via Pebax-Based Composite Membrane: Numerical Optimization

Membrane technology, particularly polymeric membranes, is utilized in major industrial ethylene recovery owing to the very convenient and robust process. Thus, this paper, a composite membrane (CM) comprising SAPO-34 Pebax-1657 was employed conduct separation performance under two operating conditions, including temperatures pressures, ranging from 25.0–60.0 °C 3.5–10.0 bar, respectively. CO2 permeability CO2/C2H4 ideal selectivity values that ranged 105.68 262.86 Barrer 1.81 3.52, respectively, were obtained via experimental works. The of carbon dioxide (CO2) (C2H4) has then been optimized using response surface methodology (RSM) by adopting central design (CCD) method. As result, operational conditions discovered at temperature 60.0 pressure 10.0 bar with maximum 233.62 3.22. typical discrepancies between anticipated data for 1.67% 3.10%, demonstrating models’ validity. Overall, new combination could inspire latest understanding
