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.

Proven Benefits: Speed, Savings, and Compliance

Benefit Impact
VOC Destruction >98% — prevented 20+ tons of uncontrolled emissions
Cost Savings $30,000+ saved vs. carbon beds (no change-outs, no freight, no disposal)
Schedule One-day job instead of multi-day carbon operation
Footprint & Logistics Single trailer — ideal for remote pipeline ROWs
Regulatory Compliance Met all state VOC rules and NSPS reporting thresholds
This project is why pipeline operators and midstream companies nationwide call Envent first for high-volume pigging, blowdowns, and tank loading events.
