Thermal Oxidation Systems
Thermal Oxidation of Gaseous Waste Streams
Thermal Oxidation is the most effective form of destruction and pollution control for liquid and gaseous waste streams. Gaseous waste streams can be grouped into three (3) main classifications:
- Contaminated Air Streams.
- Contaminated Inert Gas Streams.
- Rich Gas Streams.
1. Contaminated Air Streams are air streams contaminated with low levels of organic compounds. Examples of industries and processes which generate contaminated air streams are:
- Certain Chemical Processes.
- Coating Operations.
- Computer Chip Manufacture (semi-conductor).
- Converting.
- Drying.
- Food Processing and Baking.
- Packaging.
- Paint Booths.
- Printing Lines.
- Pulp and Paper.
- Rendering plants.
- Sewage Treatment Plants.
- Solvent Cleaning.
- Textile Finishing.
- Ventilation Hoods.
2. Contaminated Inert Gas Streams have low oxygen content (> 8% by volume) and low concentrations of organic compounds. Examples of industries and processes which generate contaminated inert gas streams include:
- Absorber Off-gases.
- Asphalt Manufacturing.
- Ceramic Industry.
- Chemical Industry.
- Diesel/Engine Exhaust.
- Heat Treating Furnaces.
- Inert Curing Operations.
- Inert Drying Operations.
- Man-made Fibre Manufacturing.
- Petrochemical Industry.
- Pulp and Paper.
- Resin Manufacturing (interim state).
- Scrubber Off-gases.
3. Rich Gas Streams have a very low oxygen content and a high percentage of combustible compounds. Examples of
industries and processes which generate rich gas streams include:
- Blast Furnace Gases.
- Chemical Industry.
- Process Upset Gases.
- CO Gas.
- Heat Treating Furnaces.
- Landfill Gas.
- Petrochemical Industry.
- Pulp and Paper.
- Reactor Exhaust Gases.
- Resin Kettle Off-gases.
- Stripper Off-gases.
- Scrubber Off-gases.
- Tank Vents.
