ABSTRACT:
A facility for reclaiming useful products from solid municipal and hazardous waste uses a rotary kiln to convert the material into a stream of inorganic ash and a stream of gaseous combustion products. The stream of combustion products passes in heat exchange relation to unburned waste and produces a stream of volatile carbon compounds which are deficient in oxygen. The streams of combustion products and volatile carbon compounds are converted in a plasma arc generator into a stream of hot, disassociated atoms. The stream of hot gas is cooled by passage through one or more heat exchangers that reclaim process heat. The stable compounds that are produced are hydrogen and carbon monoxide. The process is controlled by monitoring carbon dioxide in the carbon monoxide stream. The carbon monoxide and hydrogen may be used separately or combined, as in a methanol synthesis plant.
