Saudi water treatment for Siemens

Siemens has been selected to provide a produced water treatment system as part of an expansion at petroleum giant ENPPI’s Saudi Aramco’s Safaniya plant in the Eastern Province, Saudi Arabia. The new system will remove high concentrations of free oil from the water stream using the dissolved gas flotation (DGF) method from Siemens, so the water can be used for subsurface re-injection. The capacity will be 850,000 barrels of water per day.

Saudi Aramco uses injected water to maintain reservoir pressure to maximize oil production, and, at the moment, the system handles Arab Heavy crude oil and formation water from the Safaniya oil field and Arab Medium crude oil from Zuluf oilfields. The formation water from both fields is processed and then re-injected. Siemens Water Technologies will provide the plant with produced water treatment systems consisting of vessels using the company’s dissolved gas flotation (DGF) pump technology whichworks by using a dual sided impeller that pulls both water and gas into the pump volute.
