Catalytic treatment of VOC's and other air pollutants works by reacting the harmful air pollutants over a specially designed precious metal catalyst where VOC's are converted to CO2, water vapor (H2O), and usable heat. These harmless byproducts are released to atmosphere or use an energy recovery technique to further lower the operational costs.
CONCORD, VANGUARD and VECTOR Catalytic Oxidation systems represent cost-effective air pollution control alternatives. When compared to thermal oxidation, their lower operating temperatures (440°F - 750°F) reduce operating costs, save on fuel, and extend equipment life. Each are designed and fabricated for your specific application, each system utilizes materials and metallurgy that will afford the highest performance, longest life, and economical procurement.
The introduction and continued improvement of these revolutionary catalytic oxidizer systems are proof of Catalytic Products International's commitment to developing innovative and effective air pollution control equipment. No other manufacturer offers you the extensive knowledge - in both oxidizers and catalyst technologies - necessary to achieve the most complete and cost effective elimination of VOC's.
THE CATALYTIC OXIDATION PROCESS
The catalytic oxidation process begins with the touch of a button, which activates the system's PLC-based Temperature Safety System (TSS). The TSS control system automatically interlocks the process, energizes the blowers, purges the system with fresh air, activates the electric heater, and gradually brings the system up to the proper operating temperature. The TSS control system monitors all aspects of the oxidizers operation to safeguard against upset conditions and integrates with our operation to insure safe and economical operation.
As soon as the required operating temperature is reached, the fresh air damper closes, and one or more bypass T-dampers are open to introduce process emissions to the oxidizer. A booster fan draws one or more VOC-laden exhaust from your process lines into the system. From there, VOC's are directed either through a stainless steel primary air-to-air heat exchanger or are sent directly to a condensate evaporation section before passing through the heater element.
Once heated, the VOC-laden air stream enters the oxidizer's specially designed mixing chamber. Each system is known for the special designs employed to thoroughly mix the air stream constituents and ensure the highest degree of temperature uniformity before the catalyst bed. The well mixed stream enters the catalyst bed and reacts with any of the specially selected catalysts where an exothermic reaction occurs, leading to complete combustion of the VOC's. The clean stream either exits to the atmosphere or passes through the heat exchanger for heat recovery purposes.
Catalytic Products International utilizes multiple catalyst technology in all of their systems. Each catalyst product is specially selected by Catalytic Products International's Application Specialist based on process conditions, solvent types, desired destruction rates, ease of maintenance, etc.
