Featured Project: High-Volume Pipeline Pigging Vapor Control – 25 Miles of 16-in Heavy Crude
Clearing long crude pipelines via pigging displaces massive volumes of hydrocarbon vapors in minutes. Uncontrolled releases from a single 25-mile, 16-inch line filled with low-API crude can emit 15–30 tons of VOCs, triggering state VOC rules (TCEQ Chapter 115, SCAQMD Rule 1173, Colorado Reg 7, etc.), NSPS OOOOa/b reporting, and potential fines. Carbon beds are slow, expensive, and impractical on remote rights-of-way.
Envent’s BD-8000 is the industry’s largest mobile vapor control blower package — purpose-built for exactly these high-flow, short-duration pigging jobs.
The Challenge: Rapid Clearing of 25 Miles of 16-in Heavy Crude Line
An oil pipeline operator needed to clear 25 miles of 16-inch pipeline containing 12° API heavy crude into a receiving tank — and they needed it done fast.
Key constraints:
- Continuous pig run — no stopping once started
- Peak vapor flows exceeding 8,000 scfm
- Heavy crude = high BTU, high benzene, and potential H₂S
- Remote location — carbon delivery and change-outs would add days and six-figure costs
- Full regulatory compliance required nationwide
Envent’s Solution: BD-8000 High-Capacity Mobile Vapor Control Blower
Envent mobilized the BD-8000 direct-fired thermal blower package — the only mobile unit in North America capable of handling these extreme flows.
Delivered Performance
- Capacity: 8,000 scfm continuous
- Destruction Efficiency: >98% (verified via temperature and flow monitoring)
- Single-unit operation — no multiple trailers or complex manifolding
- Rapid setup — on-site and operational in hours
- Safe handling of oxygen-deficient and high-BTU streams with auto-purge and flame arrestors
The entire 25-mile pigging operation was completed in one continuous run with zero uncontrolled emissions. For similar high-flow applications, explore Envent’s thermal oxidizer rentals.
