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.

Abstract: A system for the abatement of industrial process emissions comprises a horizontal regenerative catalytic oxidizer (RCO). The system utilizes at least two regenerative chambers and at least two catalytic chambers in a controlled abatement process. Pollutants injected into the RCO from the process emissions are catalytically oxidized. The horizontal configuration of the RCO reduces the size of the RCO per cubic foot of emissions treated, and also simplifies maintenance requirements in removing and replacing, or regenerating, the catalyst. Chutes and valves situated above and below the catalyst provide maintenance means without the associated contamination concerns typically caused by catalytic migration throughout vertically configured RCOs.

Abstract: A filter utilizes a filter bed having a ceramic media to remove particulates from process emissions upstream of a regenerative incinerator to prevent fouling of the incinerator. To prevent the filter from fouling, the filter is adapted to "bake-off" contaminants from the filter bed by providing a flow of hot innocuous air through the filter. In addition, fluid can be flushed through the filter.

Abstract: A system for the abatement of industrial process emissions comprises a catalytic oxidizer and a selective catalytic reduction bank integrated into a single housing. The system utilizes at least two regenerative chambers in a controlled abatement process. The integrated system removes volatile organic compounds (VOCs), carbon monoxide (CO), and toxic oxides of nitrogen (NO.sub.x) from the process emissions. The singular housing of the present invention is efficient and eliminates the need for more than one supplementary heat source, while eliminating major pollutants from the emissions.
