In the King, Buck process, vapors contaminated with as much as 3,500 ppm of trichloroethylene are drawn from the soil at rates to 200 scfm, heated to 400C and passed through the catalyst bed. The volatile organic compounds are converted to carbon dioxide, water and hydrogen chloride. The air is then cooled and passed through a scrubber to remove the HCl, which is neutralized to sodium chloride and sodium bicarbonate. Not only was the catalyst able to withstand and break down halogenated hydrocarbons, it provided an added benefit over thermal-oxidation systems - no dioxin formation.
