Independent third-party testing confirms that Envent mobile units deliver destruction efficiencies of > 99%.
Envent maintains the industry’s most agile fleet of mobile scrubbers, positioned strategically to respond to unplanned emission events within hours. Whether you are dealing with a sudden storage tank leak, an unexpected pipeline excursion, or an emergency refinery vessel degassing, our logistics model guarantees that high-capacity treatment arrives on-site before odor complaints or regulatory fines escalate.
Our systems are designed for rapid setup, featuring connections that allow for immediate integration into your emergency workflow. This quick-strike capability, paired with our OQ-qualified technicians, provides an essential safety net for industrial facilities facing high-risk vapor releases. This proactive approach validates that your site remains protected and compliant, even under the most demanding emergency conditions. Each emergency deployment includes a comprehensive site safety assessment and a tailored emissions control plan to address the specific chemical profile of the release.
Engineered Vapor Control for Mobile Operations
Reducing Emissions Cost-Effectively through Industry Innovation
Our engineering team designs mobile scrubbing solutions that safely control hazardous vapors at the source. We utilize liquid scrubbers, thermal oxidizers, and media filtration based on the specific chemical product being handled to keep your site in full regulatory compliance.
Our Mobile Scrubber Services Include:
- Vacuum Truck Vapor/Odor Control: High-efficiency systems for truck-mounted operations.
- Liquid Scrubbing for Sour & Acid Gasses: Utilizing Escrub™ units with proprietary VapoScrub™ chemistry for H2S removal.
- Industrial Carbon Filtration: Specialized filters for vessel and pipeline purging.
- Tank Odor Control: High-performance vapor control units achieving 100% odor mitigation.
- High-Volume Blowers: 100 – 6,000 CFM+ units for vapor movement and safe tank entry.
- Solvent & Chemical Scrubbers: Targeted solutions for complex industrial chemical streams.
- Super High-Volume Units: 6,000 CFM+ Liquid Ring scrubbers for “Super Suckers” and “Gap Vacs”.
- MSS Compliant Systems: Solutions specifically for Maintenance, Startup, and Shutdown permit requirements.
- Certified Engineering & Testing: On-site analysis to make sure the right system is deployed for every job.
Vacuum Truck Scrubbers
Industrial vacuum operations and high-volume product transfers often generate significant vapor loads that can exceed facility emission limits. Envent’s specialized fleet of mobile scrubbers is engineered to provide a seamless interface between your vacuum equipment and regulatory requirements.
Envent provides total plant vapor management through our comprehensive line of vapor scrubbers and mobile emission control systems. The Envent Escrub™ Units, featuring proprietary VaporBite™ Technology, work alongside our EVAC and BD Units to handle any volume of hazardous gas.
These systems are supported by our field technicians and engineers, who provide carbon servicing and real-time monitoring to provide a total vapor management solution.
What Our Clients Say
Featured Case study
The Problem: A Bakken producer needed to transfer crude into 30 frac tanks. This process generated high vapor flows containing hazardous VOCs, BTEX, and H₂S. To maintain NDDEQ and EPA compliance, the site required at least 95% control in a remote area where standard carbon filters saturate too quickly.
What We Did: Envent deployed the ESCRUB-1000P passive scrubber using VapoScrubEX5 chemistry. We compared this against a control group of tanks using standard carbon. Our OQ-qualified technicians managed the liquid scrubbing system to neutralize odors and gasses without the frequent change-outs required by traditional media.
The Result: The system reached >99% control efficiency, exceeding the 95% regulatory requirement. The client saved $21,000 by eliminating three carbon swaps and extending media life by four times. The project achieved 100% compliance with zero safety incidents.

Vacuum Truck Scrubbers & Vapor Control: Frequently Asked Questions
Why are vacuum truck scrubbers now a requirement for industrial facilities?
New air quality regulations (including many local and EPA mandates) now calculate mobile-unit vapors, like those from vacuum trucks, into a facility’s total emissions limit. To prevent permit excursions, high-efficiency VOC abatement (often exceeding 99% destruction) is required for these mobile operations.
How does Envent's scrubbing efficiency compare to industry standards?
Independent third-party testing confirms that Envent’s mobile scrubbers deliver destruction efficiencies of > 99%. This far exceeds the standard 95% regulatory requirement, providing a safety margin for operations in sensitive or strictly regulated areas.
What is the benefit of a Liquid Ring scrubber for vacuum truck operations?
Our EVAC 6000 Liquid Ring units are designed for “Super Suckers” and “Gap Vacs.” They handle massive airflows (up to 6,000 CFM) while neutralizing hazardous vapors, ensuring that high-volume product transfers don’t stall due to emissions bottlenecks.
Can these units handle sour gas and H₂S?
Yes. By utilizing our Escrub™ units with proprietary VapoScrub™ chemistry, we can chemically neutralize high concentrations of H2S and acid gases. This is often more cost-effective than carbon, which can saturate instantly when exposed to sour streams.
How does chemical scrubbing save money compared to activated carbon?
In high-concentration scenarios, standard carbon filters require frequent, expensive change-outs. Our liquid chemistry has a much higher contaminant loading capacity, often extending the “media life” by four times and saving tens of thousands of dollars in logistics and replacement costs.
Are these systems compliant with Maintenance, Startup, and Shutdown (MSS) permits?
Absolutely. We specifically design our mobile systems to meet MSS permit requirements. Our field technicians provide the real-time monitoring and verified data logs necessary to prove compliance to onsite inspectors and regulatory agencies.
What is VaporBite™ Technology?
VaporBite™ is our proprietary mechanical contact technology used within the Escrub™ line. It ensures maximum interaction between the hazardous vapor and the scrubbing liquid, which is the key to achieving our >99% destruction efficiency.
Does Envent provide on-site technical support?
Yes. Every project is supported by our OQ-qualified field technicians. They manage the setup, perform real-time emissions monitoring, and handle all chemical or carbon servicing, providing a total turnkey vapor management solution.
Can you handle high-flow degassing for large storage tanks?
Yes. Our fleet includes high-volume blowers and scrubbers ranging from 100 to 6,000 CFM+. This allows us to move vapors quickly to meet tight turnaround schedules while maintaining a safe environment for tank entry.
What documentation do I receive for my compliance files?
We provide detailed, verified data logs for every project. These records show flow rates, concentration levels, and destruction efficiency, giving you a defensible “technical map” of your emissions control for environmental audits.
