CTP's Experience in the Removal of Contaminants and Odors in the Recycling Industry - A New Process for Simultaneously Removing Voes, and Dioxins and Furans

During the refining of lead, copper or other metals the furnaces used in the process · often produce waste gases. This paper illustrates how these waste gases can be successfully treated and destroyed by CTP 2-bed or multi-bed compact systems, modified for the additional reduction of dioxins and furans. The CTP regenerative thermal oxidizer also destroys voes (organic compounds and odours) using ceramic blocks as a heat exchanging media. The raw gas is forced through the ceramic beds where it is heated up to the oxidation temperature level. The voes, dioxins and furans are destroyed in the combustion chamber, subsequently generating water, eo2 and heat. The hot purified gas heats up a second ceramic bed, which is used to preheat the raw gas after the valves have been switched. This process does not produce any secondary waste such as contaminated water, polluted air or any other products that have to be disposed of.
