Molten Salt Destruction of Hazardous Materials Process and Data Update.

摘要

Current federal or state laws require controlled, documented practices for the management of specified materials designated as environmentally hazardous or toxic. Compliance with disposal criteria of these laws involves meeting strigent TOSCA or RCRA emission criteria. Disposal of hazardous or toxic material by any means that does not result in conversion of the material to ecologically harmless form sets up a continuing responsibility for prevention of damage to public health and to property. A thermal conversion process or incineration is usually recommended for the more toxic organic materials. To be successful, such a process must avoid air pollution during operation and also must produce no toxic byproducts that could result in later deterioration of groundwater quality. The molten salt process is uniquely well suited to convert many toxic organic materials into nontoxic gases and ecologically harmless byproducts. This paper describes the Rockwell Molten Salt Destruction (MSD) process and provides an update, including experimental results with polychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB), which demonstrates the high degree of destruction achievable with the MSD process. Results of bench-scale and pilot-scale tests are described. (ERA citation 09:010654)
