Abstract
A process and apparatus to deliver both process chemical and solvent for cleaning the process chemical in a solvent purge refill system along with an integral solvent sorption module, in a single 'assembly' that permits ease of shipping, minimal end-user interaction, sufficient solvent for the solvent purge operation, without residual solvent, requiring disposal. This eliminates customer handling of the solvent, and eliminates the customer's need to find a solvent waste facility, as residual solvent can be returned in the same package in one piece/one step.
