Membrane gas-solvent contactors form a hybrid technology, which undertake traditional solvent absorption within a membrane module. University of Melbourne researchers in collaboration with CO2CRC Ltd. have developed a hybrid membrane contactor process that has proven ability to be highly efficient at carbon capture with reduced energy penalty. The CO2CRC project to test and develop this technology for post-combustion carbon capture at the Vales Point pilot plant in NSW, Australia was successfully completed in March 2019. This has been the world’s first successful demonstration of membrane gas-solvent contactor technology in a continuous process in an industrial environment with simultaneous operation of absorption and solvent regeneration via membranes. The research that has been undertaken on regeneration has demonstrated that membrane contactors are competitive with traditional solvent regeneration approaches in terms of mass transfer efficiency and have a distinct advantage in terms of energy duty. The technology would lead to a compact and low-cost capture process with further research towards its commercialisation. If successful, it promises a revolutionary change in carbon capture technology.
