A classic example of chemical cleaning wastes disposal is provided by the solvent cleaning of reactors which produce polyvinylchloride (PVC) resins from vinyl chloride monomer in the growing tonnages demanded by the world. The process is such that

  1. The optimum available solvent is totally recycled back to the clean-in-place circuit.

  2. The PVC is recovered as a solid virtually free of the expensive solvent in which it had to be dissolved, making the solvent available for re-use.
