| 摘要 |
Metallic scrap containing a coating of organic insulation material is processed to recover a clean, unoxidized metallic substrate and various insulation by-products by thermally decomposing the organic insulation under pressure in a closed, externally heated vessel. Volatile decomposition products are periodically vented to a vapor recovery system and non-volatile decomposition products, primarily carbonaceous char adhering to the clean scrap, are separated by mechanical action such as vibration or tumbling. Apparatus for performing this process is also disclosed. |
