Catalytic oxidation

Catalytic oxidation is a destructive technology for the treatment of VOCs capable of achieving combustion at lower temperatures than otherwise by thermal combustion, due to the presence of a catalyst in the combustion chamber and a heat exchanger which preheats the incoming air with the exhaust purified air.

This technology is specially conceived for low flow rates with medium to high concentrations. Before using this technology, it is to be taken into account the type of contaminants found in the air to be treated, since there are some products that may poison rendering it inoperable which force its replacement.     

Oxidation reaction takes place in this type of plants with the help of a catalyzer, at temperatures of between 300° to 350° C.

These plants also have a pre-heater that recovers part of the heat energy released during gas combustion as well as a burner and catalytic bed made of noble metals (platinum, palladium), which is set up on an inert support.

Our installations offer the advantages of a catalytic regenerating system (allowing 96% heat recovery) coupled with the possibility of operating at temperatures of between 280 to 450°C, which contributes to the reduction of operating costs.
