A polypropylene membrane carbon dioxide separation system has been developed by the University of Melbourne, Australia, which could be used in power plants, according to an article published in Australian business / environmental magazine ECOS.

Teflon membranes have already been used in pilot carbon capture systems, but polypropylene is much cheaper.Polypropylene was previously rejected as a potential membrane material because it could be wet by the aqueous solvents used to absorb carbon dioxide from gas.

Canada’s Regina University, the University of Trondheim, Twente University in the Netherlands, and the University of Texas are collaborating on the project.A pilot project will be built next year to process 25 tonnes of carbon dioxide a day.
