  • Disposal of wastes with solvent recovery
    Patent number: 4708775
    Abstract: Volatile matter especially solvents is recovered from waste material using a hot granular material such as sand, as a heat carrier to drive off the solvents, and as a carrier for the non-volatile resin content of the waste; the resins are thermally decomposed in reactions which provide heat to maintain the granular material hot and the granular material is continuously circulated; the exhaust gases from the thermal decomposition of the resins can be used as a source of heat outside the system.
