Solvent recovery is the process of extracting useful solvents and raw materials from waste or byproduct solvents that are generated during manufacturing processes. The solvents that are used in these situations are often not disposed of or incinerated, but instead recovered and purified, as this saves considerable costs. Used solvents are mostly purified by means of distillation. Solvent ...
