Abstract:	This work deals with the recovery of solvents from a complex process waste stream containing methylene chloride chloroform, n-propyl alcohol, isopropyl alcohol, heptane and butyl acetate. In addition to the above-mentioned solvents, the mixture is saturated with water (ca. 1%), hydrochloric acid, and contains organic and inorganic process impurities. The objective was to develop the simplest economical recovery process utilizing vapor-liquid equilibrium data, distillation and extraction procedures. Considerable effort was expended to develop precise and reliable assay methods. A process which met the necessary requirements of maximum solvent recovery with minimum waste disposal, was developed.
