Catalytic and Recuperative Oxidisers

This is a second feature from Operational Group explaining some of the industrial equipment used to treat process air streams to destroy volatile organic compounds (VOCs) and odorous emissions from industrial processes.

Our first feature highlighted Regenerative Thermal Oxidisers (RTOs). These achieve emission destruction through a process called thermal oxidisation, using an engineered mix of temperature, resonance (burning) time, turbulence and oxygen to convert laden process air into carbon dioxide and water vapour.

However, RTOs use hot ceramic beds which are unsuitable for some industries. So this feature highlights two other types of oxidisers – catalytic oxidisers and recuperative oxidisers which use alternative abatement processes.
