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.
An energy and industrial services company needed to degas 10 compartments barge in California. Quick and effectively was required. Envent degassed each compartment in 2 hours, with a 99.9% destruction efficiency.
A tank farm customer requested Envent be onsite for an unscheduled tank refill within 4 hours. Envent was able to respond to the emergency quickly and safely, which saved the customer thousands of dollars in down time.
A customer at a Super Fund Site in Central California needed support to dewater a pit dug in a neighborhood in order to remove contaminated soil. Cost of treating and discharging the water was at a fraction of the cost.
A pipeline company in Northern California needed to blow down their natural gas pipeline for repairs and inspection. Four volume line sweeps were performed to leave the piping free of residual gas.
