In an installation comprising a solvent regeneration circuit and a solvent recovery circuit, each solvent container is connected independently to the boiler of a distillation unit for cleaning purposes. The relative arrangement of the solvent containers is such that the solvent circulates under the action of gravity from a condenser to the boiler and from each container to the boiler. The boiler is removable for subsequent disposal after filling with solvent residues and waste materials. |
