ABSTRACT:
A method for regenerating perchloroethylene by passing the fluid through a sorbent resin to remove fatty acids and other organic contaminants which reduce the fluid quality from new fluid quality. The method involves an optional step of treating the fluid with an anionic exchange resin to remove the organic dye contaminants. The key advantage over the prior art is that the process is economical, does not involve evaporative losses as realised in distillation cleaning and is environmentally friendly.
