Abstract

Hollow fiber membranes were prepared via thermally induced phase separation (TIPS) method and applied for CO2 absorption from gas mixture stream as gas- liquid membrane contactors. The percent removal of CO2 from gas mixture stream into sodium hydroxide solution was studied at varies gas flow rates. It was observed that changing the dope polymer concentration had significant effects on membrane water permeabilities, membrane morphology, membrane pore size, membrane porosity and on the gas permeation test. In addition, the performance of membranes prepared from PVDF/triacetin/glycerol shows cellular structure while without glycerol additives in the cast solution spherulite shape is observed. Almost complete removal of CO2 was successfully achieved using 2% Glycerol additives at normal operating conditions for equal gas to liquid volumetric flow rates using 0.5M NaOH solution.
