A by-product of this “flooding” is a highly corrosive brine solution that is extracted along with the oil. Technip’s system separates and stores the brine in a special tank until it is ready for the next step in the process.

On-site manufacturing
Because of the high heat and corrosive nature of the brine, the storage tank had to be made of a high-performance material. PT Graha Adhi Jaya Abadi FRP Engineering & Manufacturing, called GAJAFIBERGLASS, made the cylindrical vessel on site using filament winding manufacturing. The operation required precise control of the resin temperature prior to winding to prevent ambient heat from initiating a resin cure.

The process started with the application of an anti-corrosion liner made up of a resin-saturated surfacing veil onto a horizontal, cylindrical mandrel. The liner was backed with a structural laminate of resin-impregnated continuous fiberglass that was applied as the mandrel rotated. The finished tank is 25 feet in diameter by 16 feet high (7.6 by 4.9 meters) and has a capacity of 1,400 barrels (167,000 liters).

Corrosion and heat resistance
Gunawan Karim of GAJAFIBERGLASS said an effective presentation by Jason Triggs, technical consultant for Nuplex Composites, and a professional and quick response from AOC Corrosion Resin Product Leader Scott Lane secured the resin specification for Vipel technology.
“We verified that Vipel F080 epoxy vinyl ester was suitable for containing brine solution at temperatures up to 210° Fahrenheit (99° Celsius), which is a critical requirement for the tank,” Karim said. “Delivery of the AOC resin was excellent because we benefited from the tracking and follow-up service of Lany Aldrich, AOC Sales Manager – Asia,” he added.
