GBA selects and designs Catalytic Oxidizers when the VOC (and/or any other gaseous pollutant’s) laden stream, is present in tiny amounts in a carrier (air, or other inert).

When allowed by gas characteristics, and waste stream’s constituents (composition), the catalytic oxidation represents the best option to process lean streams with low Lower Heating Values, typically in the range of 10- 20 BTU/SCF [~0.37 to 0.74 MJ/m3], because the small organic load may be effectively oxidized on a catalyst at low temperatures, resulting in significant savings in support gas usage.

The basic concept uses a Platinum group metal-based catalyst on a monolithic honeycomb substrate in stainless steel or ceramic to induce oxidation at 300°C–400°C [572-752 °F], which is extremely low compared to a direct thermal oxidizer (850°C–1100°C, 1562°F-2012°F, or more). Destruction efficiencies of up to 99.9% may be obtained with just a little amount of support fuel, lowering total emissions.
