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 terminal located on the Northwest had to meet their deadline inspection on a large, 350,000 BBL Butane storage tank. They had a narrow window to complete the degas, turnaround work and return the tank back to service.
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.
A Houston ship channel refined product storage terminal requested our degassing expertise to engineer a solution for an unconventional sphere tank. Due to the unconventional design of the tank, previous attempts by competitors failed and the customers budget was blown. Other degassing contractors lack Envent’s engineering expertise and equipment.
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 construction company in San Diego needed to bore a hole under railroad tracks for a utility company to run wire underground, 15 ft below grade. The site location was a marine terminal, so Envent was contracted to dewater the area for digging and to treat the subsequent contaminated water. Savings of $24,000 and the successful discharge of 250,000 gallons of clean water.
Project: Condensed Water Removal from Storage Tank. Location: Victoria, Texas. Product: Water contaminated with gasoline range organics. Project finished under the allotted time and achieved a non-detect concentration of VOC’s during the project.
Project: Tank Water Treatment and Discharging Onsite. Cost Savings: $250,000. Location: Bakersfield, California. Product: Hydrostatic test water with crude oil residual.
Project: Terminal station tank to be de-inventoried. Cost Savings: $450,000. Location: Louisiana Refinery. Product: Oil and sludge-laden water
Project: Pipeline Hydrotest. Cost Savings: $550,000. Location: Alaska. Product: Hydrotest water with sediment and residual oil.
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.
