Catalytic Oxidation Systems

Catalytic oxidation is an alternative to common off gas incineration for the treatment of VOCs in air or N2 streams resulting from remedial operations. The addition of a catalyst accelerates the rate of oxidation by adsorbing the oxygen and the contaminant on the catalyst surface where they react to form carbon dioxide and water. The catalyst enables the oxidation reaction to occur at much lower temperatures than required by a conventional thermal oxidation. VOCs are thermally destroyed at temperatures typically ranging from 320° to 540° C by using a solid catalyst. First, the contaminated air is directly preheated (electrically or steam, more frequently, using natural gas or propane) to reach a temperature necessary to initiate the catalytic oxidation (310 °C to 370 °C) of the VOCs. Then the preheated VOC-laden air or N2 is passed through a bed of solid catalysts where the VOCs are rapidly oxidized.
