Thermal Oxidizers
Exceeding EPA Standards
When it comes to reducing greenhouse gas emissions and achieving complete vapor control, the Environmental Protection Agency (EPA) and Canada’s ECCC identifies thermal oxidation as Best Available Control Technology (BACT) and Best Available Technique (BAT) Facilities that generate volatile organic compounds (VOCs) must treat these emissions before release — and that’s where Envent leads the industry.
Our engineering team designs and deploys custom thermal oxidizer systems tailored to your specific vapor stream and compliance needs. Whether you’re handling anhydrous ammonia, hydrogen sulfide, benzene, butadiene, or chlorinated hydrocarbons, Envent develops pre-scrubbers and vapor destruction units that ensure safe, compliant, and efficient operation — every time.
The Power of Thermal Oxidation
A thermal oxidizer is a mobile system that destroys harmful VOCs through controlled, high-temperature combustion. The process converts pollutants into harmless water vapor (H₂O) and carbon dioxide (CO₂) — protecting both your people and the environment.
Envent’s units operate above 1,400°F and achieve greater than 99.9% destruction efficiency, setting the benchmark for environmental performance. Each oxidizer is engineered for precise temperature, residence time, and turbulence, ensuring complete vapor destruction and dependable uptime in even the most demanding field conditions.
Envent’s Thermal Oxidizers
The Envent Mobile Thermal Oxidizer System (EMTOS) defines performance and reliability in vapor destruction. Engineered and built by Envent, our systems eliminate hydrocarbon vapors with unmatched speed and efficiency — protecting both the environment and your bottom line.
With the largest and most versatile fleet in the industry, featuring burner capacities from 1.5 MMBTU to 77 MMBTU, Envent delivers the right unit for every application. That means optimized performance, lower operating costs, and guaranteed compliance — never a one-size-fits-all solution.
Each EMTOS unit achieves greater than 99.9% vapor destruction efficiency, meeting or exceeding the EPA’s Best Available Control Technology (BACT) and Maximum Achievable Control Technology (MACT) standards under the Clean Air Act, Section 112(d). Our systems destroy volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) to levels that surpass regulatory expectations, ensuring safe, compliant, and environmentally responsible operation.
To provide full transparency, every system is equipped with temperature chart recorders and digital performance logs, verifying destruction efficiency on every project — proof of performance your regulators and stakeholders can trust.

When compliance, reliability, and safety are non-negotiable, Envent delivers. Our EPA-compliant systems meet and exceed MACT and BACT standards, ensuring every project is executed with precision, performance, and environmental responsibility.
Partner with Envent for total vapor control, verified performance, and proven compliance — from project planning through final documentation.
Envent meets the EPA’s BACT and the Canadian BAP requirements and has earned the ‘Thermal Oxidizer’ designation.
EMTOS and EMECS advantages
The Envent’s fleet of Mobile Thermal Oxidizer Systems (EMTOS) and Mobile Emission Control Systems (EMECS) are the only thermal oxidizer system in the industry carrying HAZOP-certified safety and operational credentials. Designed for on-site destruction of volatile vapors, EMTOS ensures the safe removal and disposal of all waste streams, achieving unmatched reliability and compliance during refinery, terminal, and pipeline operations.
Key features include:
On-site destruction of all vapors with verified safety controls
Third-party testing confirming destruction efficiencies greater than 99% (DRE)
Certified emissions data uploaded to Envent’s secure eReport Client Portal for full regulatory compliance documentation
Safe, sealed connections to vessels during plant turnarounds
Continuous operation above 1,400°F, eliminating the need to reclassify systems as “vapor combustors” operating at lower temperatures
Proven industry-best destruction efficiency (>99% DRE)
Burner capacities up to 77 MMBTU, providing refineries with the fastest turnaround times in the industry
Scalable configurations—multiple thermal oxidizers can be run in parallel to exceed 77 MMBTU capacity for large-scale operations
EMTOS delivers the highest standard of safety, quality and performance, ensuring compliance, efficiency, and environmental responsibility in every application.
