Effect of bore fluid composition on structure and performance of asymmetric polysulfone hollow fiber membrane contactor for CO2 absorption

Performance evaluation and mass transfer study of CO2 absorption in flat sheet membrane contactor using novel porous polysulfone membrane

“…Also, the porosity of the PSF membrane was increased from %64.2 to %67.6 by addition of PVP. Porosities higher than this value [48] and lower than this value [49] were reported in the literature for hollow fiber PSF membranes. In general, the porosity of a fabricated membrane is completely dependent on the synthesis condition such as polymer concentration, additives, doping material and type of the solvent.…”

CO 2 absorption using gas-liquid membrane contactors made of highly porous poly(vinyl chloride) hollow fiber membranes

“…The rate of solvent/nonsolvent axchange is one of the key issues to determine the HFM morphology. This parameter is mainly influenced by nonsolvent/solvent/polymer ternary phase behavior as well as solvent concentration in the coagulation bath (Ghodsi et al, 2015;Rahbari-Sisakht et al, 2012b;Sukitpaneenit and Chung, 2009).…”

“…These polymers include polyetherimide (PEI) (Naim et al, 2014;Rahbari-Sisakht et al, 2012a), poly(ether sulfone) (PES) (Ghasem et al, 2012b), polysulfone (PSf) (Rahbari-Sisakht et al, 2012b, 2012c and polypropylene (PP) (Tontiwachwuthikul and Chakma, 2006;Khaisri et al, 2009).…”
