Process and operating temperature optimization for polysulfone hollow fiber membrane CO2/CH4 mixture separation via response surface methodology

Membrane gas separation has gained significant interest due to its compactness, high area-to-volume ratio, and numerous advantages over traditional gas separation processes such as cryogenic distillation and adsorption towers. Optimizing operating conditions, particularly temperature, is essential to enhance process performance, thereby increasing productivity and product purity. Polysulfone is widely regarded as an ideal membrane material for natural gas treatment due to its balanced permeance
