What is a Portable Thermal Oxidizer and How Does it Work?

At Air Clear, our Portable Thermal Oxidizers are fabricated to accommodate different process conditions and applications. Our mobile THERMOX units are ideal for customers looking for a solution to their air pollution issues, but require the APC unit to be mobile. Trailer mounted, with or without a skid, we design your unit to be easy to maneuver with a small footprint on the job site. Air Clear mobile units include a self-contained power source and can also use temporary fuel tanks.

Our Thermal Oxidizers work by destroying Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs), which are created through various industrial processes by using very high temperatures, 1500 -1,800°F, and remove dangerous emissions from the exhaust.

Our trailer-mounted thermal oxidizer is engineered to capture and eliminate harmful gas vapor from vessels, pipelines, or tanks that contain harmful VOCs & HAPs. Whether installing new equipment and need to shut down or you’re experimenting with a new process and just need a small temporary pilot unit for data, Air Clear has you covered. Our systems are safe, mobile, and highly efficient with a destruction rate of 99.999%. Contact us to get a quote started.

The portable units are ideal for applications that require temporary use, such as:

  • Remediation, Soil Treatment & Landfills
  • Oil, Gas, Energy, Ethanol, Natural Gas
  • Painting, Printing & Coating

Air Clear works with an extensive list of fortune 500 oil companies, from large refineries to small chemical plants. We perform tank, vessel, ship, barge, and pipeline degassing, as well as vapor control services. We do that by using: thermal oxidizers, IC engines, passive & counterflow vapor scrubbers, flares & granular media vapor scrubbers.

Our engineering team also markets various media for the neutralization, absorption, or adsorption of various industrial vapor streams, including liquid chemistries, granular activated carbons (made of coal, coconut shell, and specialty media). At Air Clear our experienced engineers carefully review your process data, then they work rapidly to design the proper equipment for your project.

That is because at Air Clear our units feature:

  • Customized waste stream flow rates to your application requirements
  • Trailer-mounted Portable Thermal Oxidizers
  • Fans, burner, vaporizer, and combustion chamber manufactured to industry standards and fully insulated to provide safe operation (natural gas or propane)
  • The exhaust stack is fully insulated with height above-grade-level for additional safety during discharge
  • Fully automated oxidizer operation, including system controls and safety interlocks
  • Flame trap, inlet manifold, knock-out pot, and dampers ensure safe, efficient processing
  • Low maintenance operation in outdoor environments. NEMA 4 panel and enclosure are rated for outdoor use

Air Clear has been engineering and manufacturing mobile units for over 30 years so we are more than capable of expertly providing our customers with cutting-edge designs that are cost-effective for our clients. Our units are easy to learn how to operate with onsite training from our experts and redundantly safe for any tank degassing process. Shutdowns can be costly so Air Clear not only keeps our clients compliant, but our extensive experience in the industry ensures that we adhere to strict timetables on site so you can get your process back up and running swiftly…without ever sacrificing compliance or safety.
