Several techniques can be employed for solvent recovery in catalytic processes, including:
- Distillation: This is the most common method, where the solvent is separated from the reaction mixture based on differences in boiling points. - Membrane Filtration: This uses selective membranes to separate solvents from other reaction components. - Adsorption: Solvents can be adsorbed onto solid materials and then desorbed for reuse. - Liquid-Liquid Extraction: This involves using a second solvent to selectively extract the primary solvent from the mixture.
