ABSTRACT:
A waste photopolymer plate washout fluid solvent distillation apparatus includes a single enclosure enclosing a waste washout fluid container, a recovered solvent container, and a distillation unit in which waste washout is distilled by application of heat and vacuum pressure to the waste washout, and by supplying a metered supply of a surrogate solvent to the distilled waste washout as a desired solvent is distilled from the waste washout. The apparatus, by supplying the surrogate solvent to the waste washout as the desired solvent is distilled from the waste washout, enables a greater percentage of the desired solvent to be recovered from the waste washout than has been heretofore possible with prior art apparatus, and also enables the waste washout to be disposed of as a liquid.
