Industrial Degassing & Mobile Vapor Control
SPECIALIZED INDUSTRIAL DEGASSING AND VAPOR CONTROL SYSTEMS THAT KEEP TANKS, PIPELINES, AND TERMINALS SAFE AND COMPLIANT
Degassing and vapor control are critical to get right, and industrial degassing and mobile vapor control services are far too important to leave in the hands of inexperienced operators at full‑service industrial cleaning companies.
Our engineered approach ensures every project meets strict EPA BACT and MACT standards to handle hazardous VOCs and toxic gases. With the largest mobile fleet in North America, we provide a complete solution that protects your operational integrity and the community while improving project timelines.
Our EMTOS and EMECS systems maintain the 1,400°F standard for top destruction efficiency, even in high-pressure applications over 1,000 psi. Managed by OQ-qualified technicians, we provide a zero-leak, zero-visible-flame profile to keep your facility in full regulatory standing.

Envent Corporation provides complete mobile solutions for the most complex emission challenges in North America. Our engineered approach guarantees that every project stays in full compliance with strict environmental standards while improving operational efficiency. By using the industry’s latest technology, we handle everything from high-pressure pipeline clearing to long-term tank vapor control with technical precision.
Since 1992, Envent has been a tank and vessel degassing specialist with the largest and newest fleet of mobile degassing and vapor control equipment in North America. Our team of experienced operators are able to size your tank or project appropriately to our large fleet of units. Our goal is to utilize our turn‑down ratios to optimize your timeline, while limiting propane consumption.
Our EMTOS and EMECS mobile emission control systems are designed to provide the safest, fastest, and most effective way to deliver storage tank degassing and vapor control. Envent has safely degassed thousands of tanks across the country in all types of operations and conditions including refills, sunken roofs, new construction, demolition, API inspections, and product transfers. Every storage tank degassing project is completed efficiently, safely, and in full compliance with environmental regulations.
Envent has safely degassed more pipelines than any other company in the world and continues to build on that unmatched record of success. Our pipeline degassing and vapor control systems are engineered to handle a wide range of pressure capabilities, with proven performance in both liquid and vapor service lines as well as high‑pressure applications exceeding 1,000 psi.
Whether a project requires flaring, thermal oxidizers, or scrubbers, Envent delivers the safest, most efficient, and fully compliant pipeline degassing solutions in the industry for liquid and vapor service lines.
Envent Corporation provides loading rack, railcar, and bulk storage facilities with advanced portable vapor control and emission control systems that make sure environmental permit compliance and efficient operations. Our highly trained operators and engineers have supported projects across rail, pipeline, clean fuels, crude oil, natural gas, and industrial gas terminals.
As part of our service, Envent offers optional portable vapor bladders to reduce unit load and minimize propane consumption when required, providing safe, cost‑effective, and fully compliant vapor control solutions for even the most demanding loading operations.
Envent maintains the nation’s largest fleet of portable thermal oxidizers for tank and pipeline degassing operations. Our equipment achieves the 1400 °F minimum operating standard outlined in the EPA’s Best Available Control Technology (BACT). Don’t be fooled by those firms that tell you they have something more efficient. Envent sets the standard for BACT and Refinery Service Sector (RSR) MACT‑compliant vapor control & NSPS.

DEGASING AND VAPOR CONTROL FAQs
What is tank and pipeline degassing, and why does my refinery need it?
Degassing is the controlled removal of flammable and toxic vapors from tanks, vessels, and pipelines before hot work, entry, or maintenance. It keeps vapors below explosive limits, reduces VOC and HAP emissions, and helps your refinery meet air permit and benzene fence‑line requirements during turnarounds and outages.
How long will degassing add to my turnaround schedule?
For many refinery tanks and lines, Envent can clear the explosive range in hours, not days, when the right unit size and flow rates are used. Actual time depends on tank size, product, sludge, and permit limits, but Envent sizes equipment and turn‑down ratios so degassing fits into your turnaround critical path with minimal impact.
What information do you need from our team to engineer a degassing and vapor control plan?
Typically Envent asks for tank or line dimensions, product and temperature, expected vapor concentrations or pressure, tie‑in points, site safety rules, and any specific air permit or agency conditions. With this information, Envent can design a project‑specific plan using thermal oxidizers, scrubbers, and other vapor control systems that meets your refinery’s safety and compliance requirements.
Can Envent handle high-pressure pipeline applications?
Yes, our systems are engineered to handle pressures exceeding 1,000 psi. We have safely degassed more pipelines than any other company globally, providing a complete solution for both liquid and vapor service lines.
What is the difference between your EMTOS and EMECS systems?
Our latest mobile emission control systems (EMTOS and EMECS) are designed for different scales of storage tank degassing and vapor control. Both provide the safest and most effective way to manage emissions during refills, API inspections, or product transfers while staying in full compliance.
Do your thermal oxidizers meet EPA BACT standards?
Yes, Envent maintains the nation’s largest fleet of portable thermal oxidizers that achieve the 1,400°F minimum operating standard required by the EPA’s Best Available Control Technology (BACT). This guarantees top destruction efficiency for hazardous vapors.
Are your operators qualified for industrial and refinery sites?
Yes, Every project is managed by a team of highly trained, OQ-qualified technicians. Our operators are experienced with strict safety protocols and PLC-controlled systems to maintain operational efficiency and safety anywhere in North America.
Can you manage vapors for railcar and truck loading operations?
We provide advanced portable vapor control for loading racks, railcars, and bulk storage facilities. To improve efficiency and lower costs, we offer optional portable vapor bladders to reduce unit load and minimize propane consumption.
How does Envent optimize costs during a degassing project?
Our goal is to utilize high turn-down ratios to shorten your project timeline. By using 13+ different capacity units, we size the equipment appropriately to limit propane consumption and reduce total project costs.
What types of tank conditions can you degas?
Envent has successfully degassed thousands of tanks under various conditions, including sunken roofs, new construction, demolition, and routine product transfers. We provide complete management of the process to ensure a zero-leak, zero-visible-flame profile.
