What is catalytic oxidizer?

What is catalytic oxidizer?

Catalytic oxidizers, also known as catalytic incinerators, are oxidation systems (similar to thermal oxidizers) that control VOC and volatile HAP emissions. Catalytic oxidizers use a catalyst to promote the oxidation of VOCs to CO2 and water (i.e., increase the kinetic rate).

How do catalytic oxidizers work?

Also known as a CO, CATOX, CTO, RCO, or CRO, a catalytic oxidizer works by raising the temperature of the exhaust stream to a point in which the chemical bonds that hold the VOC molecules together are broken (oxidized) across the precious metals from the catalyst media.

What is a recuperative catalytic oxidizer?

What is a Catalytic Recuperative Oxidizer? A Catalytic Recuperative Oxidizer (often called catalytic oxidizer) destroys pollutants like Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs), and odorous emissions that are often discharged during industrial processes.

What does a thermal oxidizer do?

Thermal oxidizers, or thermal incinerators, are combustion devices that control VOC, CO, and volatile HAP emissions by combusting them to carbon dioxide (CO2) and water. Thermal oxidizers are similar to catalytic oxidizers (catalytic oxidizers use a catalyst to promote the oxidation reaction).

How much do catalytic oxidizers cost?

The cost of an oxidizer can vary from $100,000 USD to over $500,000 USD, depending on system size, installation location, and the type selected.

How does a regenerative thermal oxidizer work?

Regenerative Thermal Oxidizers destroy Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs), that are created through chemical processes, and industrial exhaust steams. This type of oxidizer uses extremely high heat, about 1500°F, to clean the exhaust of dangerous pollutants and compounds.

How much does a thermal oxidizer cost?

What is the difference between a flare and a thermal oxidizer?

A flare is designed for continuous, high concentration VOCs, where it can run in steady-state without any supplemental natural gas. A thermal oxidizer (TO) is designed to operate with some amount of supplemental natural gas, either for low concentration or non-continuous applications.

How much does a regenerative thermal oxidizer cost?

Is a thermal oxidizer a flare?

While not technically a type of thermal oxidizer, the flare is similar to the direct-fired oxidizer but it does not require supplemental natural gas. Flares are used on very high concentration VOC gas streams (over 3-5% of LEL).

What is thermal incinerator?

A thermal oxidizer (also known as thermal oxidiser, or thermal incinerator) is a process unit for air pollution control in many chemical plants that decomposes hazardous gases at a high temperature and releases them into the atmosphere.

Do incinerators work?

Incinerators reduce the solid mass of the original waste by 80%–85% and the volume (already compressed somewhat in garbage trucks) by 95%–96%, depending on composition and degree of recovery of materials such as metals from the ash for recycling.
