EPA 540/A5-91/005
November 1991
The Horsehead Resource Development Co., Inc. (HRD), Flame Reactor System is
a hydrocarbon-fueled, flash-smelting system that treats heavy metal contaminated
residues and wastes. The reactor processes wastes with hot (> 2,000 C) reducing
gases produced by the combusting solid or gaseous hydrocarbon fuels in the oxygen-enriched
air. At these temperatures, volatile metals are vaporized and organic compound
are destroyed. Feed materials react rapidly in HRD's compact, low capital cost,
water-cooled reactor, resulting in high waste throughput. Treatment end-products
include a non-leachable slag, a potentially recyclable, heavy metal-enriched
oxide and in some cases a metal alloy. The flame reactor was demonstrated at
HRD's facility in Monaca, Pennsylvania in March 1991. A secondary lead smelter
soda slag was used to evaluate the reactor's ability to produce a lead- and
zinc-enriched metal oxide product and a non-hazardous slag. Approximately 72
tons of soda slag was processed during the demonstration. Greater than 75% of
the lead, cadmium, and zinc in the waste was recovered in the recyclable metal
oxide product. The effluent slag was determined to be non-hazardous based upon
TCLP criteria. The weight of the treated waste was also reduced by 36.6%. The
flame reactor experienced no major operational problems during the demonstration.
