Method for Efficient Regeneration of Solvent Mixture: Extractive Heterogeneous-Azeotropic Distillation

Abstract The fine chemical and pharmaceutical industries use large amounts of various organic solvents in their manufacturing processes. By reusing them, production costs can be significantly reduced. If we regenerate waste solvent mixtures, have the opportunity to reuse them process or other Our study illustrates an efficient regeneration using example a four-component mixture. Calculations were performed professional simulator demonstrate that highly non-ideal Water-Ethyl Alcohol-Methyl Ethyl Ketone-Ethyl Acetate mixture efficiently decomposed into azeotropic pairs thus regenerated by extractive heterogeneous-azeotropic distillation technique.
