TAPCCatalytic Oxidation

SHARE

Catalytic oxidation occurs through a chemical reaction between the VOC hydrocarbon molecules and a catalyst bed that is internal to the oxidizer system. A catalyst is a substance that is used to accelerate the rate of a chemical reaction, allowing the reaction to occur in a lower temperature range to thermal oxidisers (275°C to 350°C).

Catalysts can be specifically design for certain compounds, such as Dioxins.  As the amount of heating required is small (or zero if the gas stream is already hot enough), catalytic systems have many running cost advantages over conventional Thermal Oxidisers.

Typical applications for catalytic oxidisers include oil refinieries and chemical plants.
