Featured Project: Multi-Tank Degassing in South Coast AQMD & Central California – Dual EMTOS Fleet Solution
A California oil company needed a single, trusted partner for multiple remote tank degassing jobs in the most heavily regulated air districts in the U.S. — South Coast AQMD and San Joaquin Valley APCD.
Every project had to meet:
- SCAQMD Rule 1149 (>99.9% DRE, <10% LEL before cleaning)
- EPA BACT (>1,400 °F combustion)
- 100% redundancy & zero downtime
- Remote locations with limited laydown space
They chose Envent — the only company with 14 different-sized mobile thermal oxidizers and a perfect safety record.
The Challenge
- Multiple tanks across SCAQMD & SJVAPCD
- Variable vapor flows (low continuous vs. high peak)
- Strict <10% LEL requirement before water wash
- No room for equipment failure or breakthrough
- Full compliance with Rule 1149 and Rule 1178 in SJVAPCD
Envent’s Dual-EMTOS Fleet Solution – Size Matters
| Phase | Equipment Used | Why It Worked |
|---|---|---|
| Continuous Low-Flow Control | Small EMTOS unit | Minimized pilot gas, 24/7 reliability |
| Rapid High-Flow Degassing | Large EMTOS unit | Moved through explosive range in hours |
| 100% Redundancy | Both units on site at all times | Zero downtime risk |
| Real-Time Monitoring | Continuous LEL, flow, temperature telemetry | Instant proof of <10% LEL for cleaning crews |
Performance
- <10% LEL achieved every time — verified before cleaning
- >99.9% DRE at >1,600 °F — non-detect stack samples
- Zero odors, zero complaints, zero visible emissions
- 100% redundancy — no downtime across all sites
