Dallas refineries, petrochemical terminals, and midstream facilities carry real regulatory exposure when vapor control work is handed to a contractor without direct experience in this specific type of work. A compliance gap on a North Texas site does not just affect your project timeline. It can put your TCEQ operating permit, your workers, and your surrounding community at risk.
Envent has worked degassing and vapor control projects at Texas refineries and terminals since 1992. Our technicians understand the TCEQ air quality requirements that apply to Dallas-area facilities, and every project is executed to meet federal EPA BACT and MACT standards for VOC and H2S destruction. That field experience across over 30 years is what North Texas facility managers and terminal engineers call on when compliance and safety are not negotiable.
Every Dallas project is staffed by OQ-qualified technicians operating under OSHA 29 CFR 1910.146 confined space and hot work procedures. Envent holds a 0.0 TRIR safety record across all field operations, and every project is fully documented to satisfy TCEQ inspectors and your internal compliance review. Tier-1 operators including Irving Oil, BP, Chevron, and ConocoPhillips have trusted Envent for vapor control work at their facilities when compliance and safety were not negotiable.
” They provided timely communication and, with the support of their teams, contributed to a safe Turnaround. Their quick response to events helped us maintain our commitments to safety and the environment. I would not hesitate to recommend them to lead crews on other jobs.”
“They deliver exceptional performance, over and beyond our expectations contractually.”
Based on this experience, I am comfortable recommending Envent Corporation for any degassing, vapor control, or related services. Their technical capability and consistent performance make them a dependable service provider.

Envent has worked mobile degassing and vapor control and water treatment projects at Texas refineries, terminals, and pipeline facilities since 1992. That 30-year field record across North Texas and the Gulf Coast is what Dallas-area facility managers rely on when they bring Envent back for the next job.
When selecting a vapor control contractor, five things matter: experience, safety, compliance, service, and cost. Envent has worked with operators including ExxonMobil, Chevron, Shell, and Valero by putting OQ-qualified technicians on every job and maintaining a 0.0 TRIR safety record with full TCEQ and EPA compliance documentation on every project.
Dallas refineries, petrochemical terminals, and midstream facilities face some of the most demanding vapor control requirements in the country under TCEQ air quality rules. Envent brings field-tested mobile degassing and vapor control crews to North Texas projects ranging from high-pressure pipeline work to long-term storage tank vapor control. Every project is executed to meet TCEQ and federal EPA standards, with OQ-qualified technicians managing the work from mobilization through final compliance documentation.
Envent has worked tank and vessel degassing projects across Texas since 1992, operating the largest mobile degassing and vapor control fleet in North America. Our crews size every Dallas-area tank project to the right unit based on tank dimensions, product type, and your turnaround schedule.
We apply turn-down ratios across 13 or more capacity units to shorten your project timeline and keep propane consumption in check.
Envent’s EMTOS and EMECS mobile emission control systems are built for storage tank degassing and vapor control at Dallas-area refineries, terminals, and petrochemical facilities. Our crews have degassed thousands of tanks across the country under a wide range of conditions, including refills, sunken roofs, new construction, demolition, API inspections, and product transfers. Every Dallas storage tank degassing project is completed safely and in full compliance with TCEQ and EPA environmental regulations.
Envent has degassed more pipelines than any other company in the world, with proven performance in both liquid and vapor service lines and high-pressure applications above 1,000 psi. Dallas-area pipeline projects requiring flaring, thermal oxidizers, or scrubbers are handled by OQ-qualified technicians under TCEQ and EPA compliance requirements, with full documentation for regulatory review. Envent has worked pipeline degassing projects at Texas refineries and terminals since 1992.
Envent provides loading rack, railcar, and bulk storage facilities across the Dallas area with portable vapor control systems built to meet TCEQ permit requirements. Our operators have worked projects across rail, pipeline, clean fuels, crude oil, natural gas, and industrial gas terminals throughout North Texas.
Portable vapor bladders are available to reduce unit load and lower propane consumption within TCEQ and EPA permit conditions.
Envent runs the largest portable thermal oxidizer fleet in North America. Every unit reaches the 1,400°F minimum operating standard required under the EPA’s Best Available Control Technology (BACT). Dallas-area refineries and terminals requiring BACT and Refinery Service Sector (RSR) MACT-compliant vapor control work with Envent, with every project fully documented for TCEQ and NSPS compliance review since 1992. Our thermal oxidizers cover tank and pipeline degassing across North Texas.
Degassing is the controlled removal of flammable and toxic vapors from tanks, vessels, and pipelines before hot work, confined space entry, or maintenance. Dallas-area facilities operating under TCEQ air quality permits must keep VOC and H2S emissions within permit limits during turnarounds and inspections. A single compliance gap can put your operating permit and your workers at risk. Our degassing and vapor control services cover the full scope of work.
Yes. Envent has worked vapor control projects at Texas refineries, terminals, and midstream facilities since 1992, including sites across Dallas and North Texas. Every crew arrives OQ-qualified and ready to meet TCEQ and federal EPA requirements on your schedule.
Timeline depends on tank size, product type, vapor concentration, sludge levels, and your TCEQ permit conditions. Envent applies turn-down ratios across 13 or more capacity units to clear the explosive range in hours rather than days on most Dallas-area tanks. This keeps degassing within your refinery turnaround critical path with minimal schedule impact.
Every Dallas project is executed to meet federal EPA BACT and MACT standards for VOC and H2S destruction.
