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.
