Catalytic Oxidizers

SPECIAL FEATURES INCLUDE:

There are many different types of VOC abatement systems.In the Catalytic Oxidizer VOC destruction occurs by chemical reaction. This is achieved at relatively low temperatures typically between 500°F to 750°F.

The Catalytic Oxidizer consists of a chamber that is lined with an insulating high temperature ceramic fiber, a catalyst, and a burner which maintains a preset operating temperature from 500°F to 750°F depending upon the VOCs to be abated and the pollution abatement equipment design. The VOC laden air passes through the combustion chamber where the catalyst oxidizes the VOC into carbon dioxide and water.
The catalysts can be provided in pellet form or as a solid monolith. The catalyst itself can be a layer of precious metal(s) on a ceramic, alumina or metallic substrate. For base metal catalyst the base metal is often mixed with alumina and is provided in a pellet from.
If a palletized catalyst is used, the pellets are arranged in basket type containers so that the VOC laden air passes through the catalyst bed normally from the top down.

If a Monolithic catalysts is used, it is mounted in frames and the VOC laden air can pass through this bed configuration in any position. Catalytic Oxidizers are provided complete with Factory Mutual (FM) or IRI fuel pipe train, controls, control panel and process blower.

HEAT RECOVERY:

To reduce support fuel consumption, a heat exchanger may be utilized to capture the hot exhaust from combustion. This captured heat may be use to preheat the incoming VOC laden air stream before entering the combustion chamber of the oxidizer.

The hot exhaust can also be passed through a boiler to produce steam, hot water or hot oil for process heating requirements.
