| Technique | Description | Applicability | |
|---|---|---|---|
| a. | Material recovery | Solvents are recovered from the distillation residues by evaporation. | Applicability may be restricted when the energy demand is excessive with regards to the quantity of solvent recovered. |
| b. | Energy recovery | The residues from distillation are used to recover energy. | Generally applicable. |
