Thermal oxidization is a process that destroys hazardous compounds at high temperatures and converts them into carbon dioxide, water vapor and heat before releasing them into the atmosphere.
Oxidizers
Direct-Fired Thermal Oxidizers
Direct-Fired Thermal Oxidizers (DTFO) destroy emissions that are created through chemical processes found in industrial exhaust streams through the process of combustion. By raising the exhaust stream temperature, the molecules are safely broken down into carbon dioxide (CO2), water (H2O) and thermal energy.
Thermal Recuperative Oxidizers
A Thermal Recuperative Oxidizer (TRO) uses thermal oxidation to treat industrial exhaust streams by converting emissions into carbon dioxide (CO2). A TRO is like a direct-fired thermal oxidizer but also has primary or secondary heat recovery, allowing the system to be powered by some of its own energy. The heat collected is used to preheat the chambers, instead of using natural gas to heat them.
Regenerative Thermal Oxidizers
Regenerative Thermal Oxidizers (RTO) are used to destroy high volumes of emissions that are created through chemical processes, as well as those from industrial exhaust streams. Extremely high heat treats the exhaust of dangerous pollutants and compounds using ceramic media. RTOs are commonly configured in two, three and multi-canister systems to meet any organizations’ needs for ensuring odor and organic material are destroyed. RTOs are a great solution for any process that requires continuous operation.
Catalytic Oxidizers
A Catalytic Oxidizer (CATOX) is used to abate industrial exhaust streams using media and heat together. Catalytic oxidizers raise the temperature of the exhaust stream to break apart the chemical bonds that hold the Volatile Organic Compounds (VOC) molecules together using media in the system as a catalyst. The molecules are converted to carbon dioxide (CO2), water (H2O) and thermal energy. The use of media allows for the operating temperature of a CATOX to be lower than a traditional thermal oxidizer, which uses less energy and requires less fuel.
Enclosed Flares
Enclosed Flares are used to destroy high concentrations of Volatile Organic Compounds (VOC) and other combustible compounds in areas where an open flame is not permissible and typically where the gas stream has low levels of oxygen. The mixture of added air and the flare destroy the chemical bonds of the compounds and converts the pollutants into combinations of carbon dioxide (CO2) and water vapor. Enclosed flares are an excellent option for strict air quality regulations and for facilities that require equipment with a small footprint.
Vapor Combustor Units
Vapor Combustor Units (VCU) operate at high temperatures to break apart the chemical bonds of molecules. The chamber of a VCU is typically lined with high-temperature insulation to protect the outer steel shell and a soft refractory lining is installed to allow for rapid heat up and reduce expansion and contraction. VCUs are ideal for applications that require cyclic operation or systems that require transportability. Different than a thermal oxidizer, VCUs process a vent stream that is not flammable until it reaches the inside of the VCU combustion chamber.
Scrubbers
Scrubbers remove dangerous particles from industrial gas streams without burning or using fuel. Scrubbers are ideal for applications that require high temperatures, highly acidic exhaust streams, or harsh chemicals.
Carbon Adsorbers
Some industrial applications or compounds require other types of pollution control equipment or additional solutions to create a complete system to neutralize certain chemical bonds or pollutants. Carbon adsorbers can be used on their own, or in addition to other pollution control abatement.
Carbon Adsorbers use filtration to abate Volatile Organic Compounds (VOCs) in low concentration gas streams in VOC abatement, no NOx, and solvent recovery. There are several types of carbon adsorbers, but the most common are Fixed Bed and Fluid Bed Adsorbers.
Fixed Bed Adsorbers can control continuous, VOC-laden streams, over a wide range of flow rates and can be run intermittently or continuously.
