ABSTRACT:
A halohydrocarbon solvent recovery process. The process in one embodiment included heating a gross mixture including solvent, fatty-acid impurities and water in a bath to vaporize at least a portion of the solvent and the impurities. A portion of the vapor is then condensed in a reflux condenser to form a condensate mixture. After drying and impurity adsorption, a solvent product of at least 99% purity may be recovered. In one embodiment, the gross mixture is obtained from steam stripping dry-cleaner filter cartridges.
