HF is the major building block for fluorination in the development of fluorochemicals used in refrigeration, Fluoropolymers and many other industries.  Recovery of HF using membranes is difficult due to the harsh nature of HF.  Other chemical separations also involve exposure to harsh chemicals.  We propose developing novel chemically resistant membranes for separating HF from Fluorochemicals.  These novel chemically resistant membranes will also be valuable in many other harsh chemical separations.  Phase I will fabricate and evaluate thin, flat sheet membranes having the desired chemical resistance in both single and mixed gas environments.  Small tests on split streams will be done at plant sites.  Engineering simulations and economic evaluations will determine potential value.

 

Commercial Applications and Other Benefits as described by the awardee:  Numerous harsh chemical separations require chemically resistant membranes.  HF/Fluorochemical separations and chlor-alkali tail gas separations represent two initial applications.  This CMS technology provides for the first time a fully perfluoronated system for harsh chemical separations.
