Abstract
A method for the abatement of contaminant-laden process emissions produced by various wood manufacturing processes comprises the step of flowing the emissions through an oxidation catalyst located in a regenerative catalytic oxidizer to remove volatile organic compounds (VOC's), methanol, formaldehyde, resins, binders, and hazardous air pollutants (HAP's) at lower peak temperatures than the temperatures encountered in regenerative thermal oxidizers. The oxidation catalyst allows the overall abatement process to operate at lower peak combustion temperatures. By reducing the peak combustion temperatures during the abatement of emissions, the present invention precludes potassium and/or sodium in the emissions from reacting with silica in the heat recovery media and ceramic fiber insulation of the regenerative thermal oxidizer. This reaction has heretofore destroyed the desired properties of the wood product and compromised the quality of the product.
