Potential effect of potting resin on the performance of hollow fibre membrane modules in a CO2/CH4 gas separation system
description This study investigates the effects of epoxy and polyurethane resins when utilised as a potting resin in a hollow fibre membrane module used for CO2/CH4 separation. Due to swelling and shrinkage of the tubesheet, the permeation flowrates observed have shown significant fluctuations, thus, affecting the overall purity obtained by a membrane module. This clearly shows that not only the quality and variation of the hollow fibre membranes affect the results obtained by a hollow fibre membrane module, but also the selection of potting resins. Four samples comprising of 2 epoxy samples and 2 polyurethane samples were used to pot 50 strands of polysulphone hollow fibre membranes from the same batch of spinning. Utilising different feed concentrations of CO2/CH4 gases and operating pressures, permeation flowrates for the modules potted with the four samples were observed using a hollow fibre membrane gas separation testing apparatus.
