Catalytic dioxin destruction system is a low -temperature technology for flue gas dioxin emission destruction. The dioxin destruction catalyst enables dioxins to be reduced to extremely low levels at low flue gas temperatures, even as low as 320° F (160° C). It destroys dioxin compounds in a single process step, with no subsequent processing needed. In addition, the CRI process does not require the addition of any reactant beyond the oxygen already in the flue gas. The CRI system uses a specially developed catalyst to convert dioxins to a mixture of harmless gases. This system is applied for both liquid waste incinerators after the wet acid gas scrubber, and to solid waste incinerators after the acid gas and particulate removal systems.
