Challenge
A petroleum refinery scheduled a turnaround that required taking several gasoline vessels and process units out of service. As part of the refinery turnaround services, the first step was to identify the vapor point on where we would perform the vessel degassing—depressurizing and decontaminating the units of Volatile Organic Compounds (VOCs) and Hydrogen Sulfide (H₂S).

Solution
Envent was contracted to supply two temporary vapor degassing and Hydrogen Sulfide (H₂S) vapor control systems to safely and efficiently combust VOCs from the process units. As part of its refinery turnaround services, Envent provided two high-pressure regulators to manage high inlet pressures and reduce them to a controlled level. Additionally, two recirculating caustic scrubbers were deployed to neutralize Hydrogen Sulfide (H₂S) before the vapors were combusted by Envent Mobile Emission Control Units (EMECs). Envent delivers the most advanced degassing technology available for gas scrubbing and tank and vessel degassing applications.

Benefit
Envent delivered a safe, efficient, and compliant solution for vessel degassing and vapor control during the refinery turnaround. The high-pressure regulators ensured a controlled pressure reduction for safe operation. Recirculating caustic scrubbers effectively neutralized Hydrogen Sulfide (H₂S), minimizing environmental and health impacts. The thermal oxidizers in the Envent Mobile Emission Control Units (EMECs) efficiently combusted vapors, achieving regulatory compliance and reducing emissions. The integrated vapor control system—combining H₂S scrubbing with Envent Mobile Emission Control Units (EMECs)—streamlined the turnaround process and enabled VOC controls, maintenance and modifications to proceed on schedule, achieving vapor-free status and environmental compliance ahead of plan.
