Description

Thermal Oxidizers and Catalytic Oxidizers for abatement of Volatile Organic Compounds (VOC) during binder burnout.

Thermal Oxidizers and Catalytic Oxidizers are typically used to destroy Hazardous Air Pollutants (HAPs) and Volatile Organic Compounds (VOCs) from industrial air streams. These pollutants are generally hydrocarbon-based and when destroyed via thermal oxidation, they are chemically changed to form CO2 and H2O.

The National Environment Policy Act (NEPA) of 1969 established national policies and goals for the protection of the environment. The California Environment Quality Act (CEQA) was adopted in 1970. A local government agency, Air Quality Management District (AQMD) has primary approval authority over projects that have not previously undergone a CEQA analysis.

The EPA and local AQMD often require these units for air pollution control to decompose hazardous gases before they’re released into the atmosphere.

Thermal oxidation is usually accomplished in one of two ways, either by heating the effluent to a temperature high enough to cause spontaneous combustion in the presence of air, or by passing both the effluent and air over a catalyst bed that has been heated to a somewhat lower temperature sufficient to cause catalytic combination. Catalytic thermal oxidation is generally performed at a temperature approximately half that of traditional combustion based thermal oxidation.
