Catalytic VOC removal

As global regulations on volatile organic compounds (VOCs) are getting stricter, staying compliant is more important than ever. Our catalytic oxidation solution, CATOX™, removes over 99.9% of the unwanted VOCs from refinery or chemical plant off-gases, without generating secondary pollutants.

Our catalytic oxidation solution for the removal of volatile organic compounds (VOCs) is called CATOX. The solution provides a straightforward, reliable way to make VOC compliance affordable, so you can be sure of a “license to operate” – both now and in the future.

The catalysts from the extensive CATOX portfolio can oxidize nearly any industrial gas impurity you might be dealing with – from easily treated compounds like hydrogen to the most challenging ones like short alkanes.

The CATOX solution can be retrofitted into your existing reactor. Whether you have a new catalytic oxidation unit project, a regenerative catalytic oxidation (RCO) design, or an existing regenerative thermal oxidation unit (RTO), the CATOX design is flexible to fit in perfectly. 

Our extensive catalyst portfolio includes a variety of shapes, like pellets, rings, and monoliths, suitable for a variety of industrial applications and in various temperatures, from room temperature to 650 °C. These catalysts are based on carefully selected combinations of precious and/or base metals on a carrier, and efficiently oxidize even the toughest molecules, such as methane. 

A common regenerative thermal oxidation (RTO) unit can be modified into a RCO installing a layer of catalyst monoliths.

Alternatively, a catalytic reactor can be installed downstream an RTO, using its heat for final gas purification.
