ABSTRACT:
Apparatuses and methods for treating gas streams containing variations in VOC concentration whereby the VOC's are destroyed in a combination non-catalytic/catalytic oxidation system are disclosed. A non-catalytic destruction matrix composed of inert ceramic materials that enhance process mixing and provide thermal inertia for process stability is used when VOC concentrations are high and a catalytic oxidizer is principally used when VOC concentrations are low. The exhaust from the non-catalytic destruction matrix is passed through the catalytic oxidizer to maintain proper catalytic oxidizer operating temperatures. Supplemental fuel and air are added as appropriate upstream or downstream of the non-catalytic oxidizer to maintain proper heat values in each portion of the system.
