A pervaporation apparatus was designed and tested in an effort to develop an integrated fermentation and product recovery process for acetone—butanol—ethanol (ABE) fermentation. A crossflow membrane module able to accommodate flat sheet hydrophobic membranes was used for the experiments. Permeate vapors were collected under vacuum and condensed in a dry ice/ethanol cold trap. The apparatus containing polytetrafluoroethylene membranes was tested using buta.
