SOLVENT CLEANING AND RECOVERY PROCESS Abstract of the Disclosure A process is provided for the solvent cleaning of vinyl halide polymers from the internal surfaces of reaction equipment and for the recovery of the solvent used therein comprising con- tacting the internal surfaces with a solvent for vinyl halide polymers and removing vinyl halide polymer-containing solvent from the reaction equipment. The improvement in the process comprises the steps of: (1) contacting the polymer-containing solvent with steam; (2) separating the resulting slurry into an aqueous solvent and a precipitate; (3) adding water to the precipitate to form a second slurry; and (4) separating the second slurry into a second aqueous solvent solution and vinyl halide polymers. The aqueous solvent solutions are dehydrated before being reused in solvent cleaning. -1-
