Challenge
A California refinery terminal needed to load gasoline, ethanol, and other high vapor pressure materials (classified as MVR products) onto barges. These Marine Vapor Recovery (MVR) products require vapor control during marine loading to comply with stringent USCG regulations (33 CFR 154 Subpart P).
However, the terminal lacked any fixed vapor recovery equipment at the dock. Without a temporary vapor control solution, the refinery risked losing substantial revenue opportunities from the inability to load and sell these valuable products.
Solution
Envent Corporation provided a USCG-certified Marine Vapor Control System (MVCS), specifically engineered to meet all marine vapor recovery requirements. The solution included:
-
The industry-leading EMECS (Envent Mobile Emission Control System) thermal oxidizer to destroy vapors safely and in full compliance with EPA BACT standards
-
Envent’s Dock Safety Unit (EDSU) to ensure safe vapor handling at the marine loading interface
-
Full system design and installation in accordance with USCG 33 CFR 154 Subpart P, including pipeline sizing, PRV/VRV requirements, safe distances, and equipment certification
Envent’s engineers and project managers coordinated with site personnel, crafts, and regulatory bodies to ensure seamless installation, testing, and operation. A third-party USCG-certified inspector provided a compliance certification letter, now maintained in the terminal’s regulatory files.
Benefit
With Envent’s mobile vapor control solution, the refinery terminal successfully loaded MVR products at a rate of 7,500 BBL/hr onto ships and barges, unlocking significant operational and financial benefits:
-
Maintained full regulatory compliance with USCG marine vapor recovery regulations
-
Increased throughput and profitability with faster, more efficient loading capabilities
-
Avoided capital investment in permanent infrastructure through Envent’s temporary vapor recovery solution
-
Enhanced operational flexibility to continue marine shipments of gasoline, ethanol, and other high-BTU products
Over the next few years, this project is expected to generate millions in additional revenue for the terminal—further solidifying Envent’s reputation as the industry leader in mobile marine vapor control systems, thermal oxidizer technology, and turnkey emission compliance solutions.
