Challenge
A Gulf Coast refinery engaged Envent Corporation for an emergency depressurization and vapor control solution on a pipeline running 3.5 miles south of the refinery. The pipeline required immediate depressurization and degassing to allow for emergency inspection and repair. Simultaneously, the customer identified the need to de-inventory and depressurize an LPG Bullet tank during the same timeframe.
Both projects presented a critical need for efficient vapor control, hydrocarbon vapor destruction, and regulatory compliance to minimize downtime and emissions risks.
Solution
Envent responded with its EMECS (Envent Mobile Emission Control System) and experienced emergency response team, delivering a cost-effective, turnkey solution. The same crew and equipment were used to perform both services consecutively:
-
Pipeline depressurization and degassing to safely remove vapors for maintenance access
-
LPG Bullet tank depressurization and degassing utilizing the EMECS thermal oxidizer to destroy vapors with >99.9% destruction removal efficiency (DRE)
Envent’s approach maximized efficiency while ensuring compliance with emissions regulations and safe vapor handling for both systems.
Benefit
Envent’s rapid response and engineered vapor control solution delivered multiple benefits:
-
Time and cost savings through a 2-in-1 service with a single mobilization and demobilization
-
Reduced downtime enabled the refinery to perform additional maintenance that would have otherwise been delayed
-
Safe, compliant degassing for both the pipeline and LPG Bullet tank without exceeding emissions permits
-
Streamlined operations with Envent’s mobile thermal oxidizer systems, eliminating the need for additional resources or vendors
This project further demonstrates Envent’s leadership in pipeline vapor control, LPG vapor mitigation, emergency response degassing, and thermal oxidation solutions—helping customers maintain safety, compliance, and operational efficiency.
