One of the most widely accepted air pollution control technologies across the industry is the Regenerative Thermal Oxidiser (RTO).
Why Choose RTO?
A catalytic oxidiser, also known as CO, CATOX, CTO, RCO or CRO, is used to abate industrial exhaust streams that emit VOCs. Through catalytic oxidation, which occurs through a chemical reaction between the VOC hydrocarbon molecules and a precious-metal catalyst bed that is internal to the oxidiser system, the VOCs are converted to carbon dioxide (CO2) and water (H2O).
Why Choose CATOX?
A less common pollution control equipment is the thermal recuperative oxidiser. Thermal recuperative oxidisers treat industrial emissions containing VOCs and particulates. Through thermal oxidation, the VOCs and hazardous air pollutants (HAPs) are converted into harmless carbon dioxide. TROs have a primary and/or secondary heat exchanger within the system, which preheats the chambers.
Why Choose TRO?
Direct Fired Thermal Oxidisers utilises the simplest thermal oxidation technology. The DFTO destroys VOCs and HAPs through the process of combustion. Also called afterburners, these systems are the most inexpensive, but when applied incorrectly, the operating costs incurred can be hefty due to the lack of heat recovery.
Why Choose DFTO?
In compliance with regulations, the high release of NOx into the atmosphere is prohibited as they are harmful greenhouse gases. Using a NOx abatement system, the NOx emissions are converted into harmless elements, such as oxygen, water and nitrogen. The abatement system consists of a NOx reducing catalyst and an ammonia injection system. Depending on the application, the catalyst can be modified.
A carbon adsorber is a popular choice among air pollution control technologies and utilises a filtration method. This equipment is used to abate VOCs in low concentration waste gas streams. Primarily, a carbon adsorber is chosen to achieve VOC abatement, no NOx and recovering solvents.
As the gas flows through an activated carbon bed, the VOCs are trapped on its surface. The adsorption system can be used with various types of activated carbon that can be thermally or chemically activated to provide a large surface area.
