Abu Dhabi oil company
The client is a national oil company in the emirate of Abu Dhabi, United Arab Emirates. The overall project involves developing an offshore oil field.
The client was looking for a partner to supply a Produced Water Treatment plant to separate oils and suspended solids from water and allow reinjection or disposal.
Produced waters contain an extremely high concentration of chloride and hydrogen sulfide.
Due to the offshore installation, the equipment had to be compact, lightweight, and of the utmost reliability.
Hydrocyclones are the most compact and reliable liquid-liquid separation technique.
The highest-quality metals and components are used; the piping and internal cladding of the vessels are made with Inconel 625, an alloy containing 58% nickel, plus chromium, molybdenum, niobium, tantalum, and other metals that make it highly resistant to oxidation and corrosion.
The supplied solution
Oil is first separated from the water via deoiling hydrocyclones, after which the residual gases are separated by lowering the pressure in two degassing units.
