Challenge

A customer at the Port of Brownsville was preparing a mid-sized high RVP gasoline tank for an API 653 inspection. The tank, which was fed by a pipeline, was assumed to be empty of product. However, upon further inspection by the client and their tank cleaning contractor, it was discovered that over one foot of gasoline product remained at the bottom—concentrated near the sump and water draws. This unexpected finding introduced potential vapor hazards, compliance risks, and scheduling delays.

Solution

Envent Corporation worked closely with both the customer and the cleaning contractor to provide continuous, 24/7 mobile degassing and vapor control services. Our thermal oxidizer systems and expert operators ensured safe handling of petroleum vapor control throughout the operation.

• Envent deployed mobile equipment configured to manage low and high BTU vapor streams while reducing vapor concentrations to meet the facility’s air permit limit of <10% LEL

• We applied vapor scrubbers and thermal oxidation technology tailored for high-RVP gasoline applications

• Our team continuously monitored vapor levels and adjusted the system to maintain control, ensuring full regulatory compliance under local and federal guidelines

Benefit

Despite a few minor setbacks during execution, Envent’s team adapted quickly, upheld safety standards, and delivered the project ahead of schedule. The collaboration between Envent, the facility, and the cleaning contractor allowed the job to be completed safely and efficiently.

This project highlights Envent Corporation’s expertise in tank degassing for refineries, pipeline vapor control, and turnaround vapor control. Backed by the largest fleet of mobile thermal oxidizers, our team remains committed to our core priorities: Safety, Compliance, and Quality of Service.
