发明名称 Process for solvent recovery and apparatus suitable therefor
摘要 An apparatus is described for recovery and reuse of liquids which are used as solvents and for the specific dilution of the solvent in the chemical reaction and/or the processing of substances. The process includes: a) introducing fresh solvent (2) into a processing plant (3), b) introducing fresh diluent (5) into the processing plant, c) introducing substances (7) to be reacted and/or to be processed into a treatment apparatus (8) of the processing plant (3), d) ejecting products (10) from the processing plant (3), e) feeding the used mixture (12) to a solvent recovery plant (13), f) separating the mixture from step e) in the solvent recovery plant (13) into a solvent fraction (15), which is primarily composed of solvent and possibly contains a small proportion of diluent, into a diluent fraction (17), which is primarily composed of diluent and possibly contains a small proportion of solvent, and into residues from the reaction and/or processing of the substances, g) returning the solvent fraction (15) to the processing plant (3), so that this fraction is again available for the reaction and/or processing of the substances, and h) returning the diluent fraction (17) to the processing plant (3) so that this fraction is again available for the reaction and/or processing of the substances, i) ejecting residues from the reaction and/or processing of the substances from the processing plant.
