Anybody came across separation of ethanol water / IPA water by pervaporation membrane process, rather than azeotrophic distillation.
If so can i get the details of supplier who can provide the whole system.

Thanks for the team for helping me in advance.

The main suppliers are

www.sulzer.com
If you google them and pervaporatiuon you will get the pervaporation page. They have supplied approximately 150 plants worldwide.
www.mtrinc.com is an American supplier.


Both of these should be able to supply your needs. However a word of caution, pervaporation has been around since the 80's and for all its hype, it has not dominated and replaced distillation in the solvent recovery or even the easier bioethanol market. A lot of this has to do with the lack of knowledge but alos to do with lack of suppliers and lack of membrane stability. Vaperma a recent entry but the websaite is down (vaperma linkedin does work though). There were strong indications that it could not get enough additional funding at the start of the year.
