Catalytic Oxidizer Systems

Since 1975, CEE has been utilizing the catalytic oxidizer approach to allow air pollutant destruction to take place at lower temperatures with the use of catalysts, consequently saving operating costs. These units contain a catalyst section after the combustion chamber that allows the VOC's to be destroyed at a lower temperature.

Depending on the application and type of catalyst used the destruction of the VOC's takes place at temperatures from 500 to 600° F.

Through the catalyst VOC's release their heat, for example if the airstream contained 10% LEL, the heat release would produce a leaving temperature of 850° F. The waste heat can then be recovered by primary heat exchangers that preheat the incoming process exhaust and result in VOC destruction without any auxillary fuel being supplied.

Some of the advantages of a catalytic system over a recuperative system is that the primary heat exchanger would cost less due to the fact that the exhaust temperatures are usually less than 1,000° F. Since the destruction takes place in the catalyst, the unit does not require a long retention time making the combustion chamber smaller and the overall size of the unit less than that of a recuperative unit.

Company's that produce the same product every day can benefit from a CEE Catalytic Oxidizer in that you know what is contained in the airstream and you can predict what you will be producing 3 years from now making the catalytic unit a reliable effective air pollution control method.
