A Westlake Louisiana refinery required vapor control on their tank while a robotic crawler made entry into the tank. The company was trying to recover $10,000,000 worth of catalyst that had carried over from their Catalytic Cracking Unit. Envent was also requested to provide vacuum rated carbon containers.
A refinery with a sour water tank high in H2S needed vapor control provided during a turnaround while maintenance was done in the surrounding area. The H2S needed to be reduced to a safe level while the vapors were treated and vented to atmosphere. Successfully reduced the H2S emissions in the area so turnaround could continue.
A large Texas refinery was in need for a long term vapor control solution for their refinery. A system that was specifically engineered for the concentration of VOCs and SOx. Neutralized any harmful VOC’s to the environment in the most effective manner.
A large refinery in California needed vapor control on a propane recovery line. In order to stay within the permit, the refinery would have to degas the pipeline to accommodate the Bay Area AQMD limits. A quick and easy vapor control solution was needed. 600 pounds of VOC’s removed just under five hours.
A petrochemical company needed both vapor control, and degassing for a spherical 30,000 barrel Butadiene tank. Envent was able to quickly switch from a vapor control, to a degassing service with little to no downtime, and ahead of schedule.
An Oil and Gas terminal had mixed 350 BBL of product inside a pipeline. The company was going to push the mixed product to a LPG transport truck using a pig, and Envent was requested to control vapors on the truck to prevent it from overpressuring. Successfully purged the pipeline of the mixed product in 6 hours of operation.
A 180,000 BBL Southern California refinery wastewater tank, frac tanks and centrifuge equipment needed vapor control and degassing during sludge removal. The two month long project needed redundancy and great attention to detail to abide by the permitting requirements. Maintained 24/7 operation while making the short generator service intervals.
The challenge was to handle the vapor control for 250 frac tanks and the blow downs from the towers, columns, and vapors from the vacuum trucks. Envent’s 24 hour manned operation ensured the tank was degassed correctly and safely.
A pipeline company required emergency treatment and discharge of contaminated water to the Los Angeles City Sanitation system during a construction project. The effluent pipeline water properties varied over time due to numerous drilling and grouting activities occurring upstream of the effluent.
Treat and discharge 3,000,000 gallons of water from a pipeline hydrotest on the North Slope of Alaska. Protected America’s last frontier while minimizing costs.
A chemical plant in Texas required a 24,000 barrel tank to be degassed during, and following a tank cleaning. Degassing Tanks under a Nitrogen Blanket Not a Problem for Envent.
During a pipeline re-commissioning a leak was detected requiring 12,000 barrels of propane needing to be combusted. By using the vapors in two ways, the time to depressure the pipeline was completed 4 times as fast.
