Veolia Awarded Wastewater Treatment Contract in Qatar

Veolia, through its subsidiary Veolia Water Technologies, has been awarded a contract by Qatar Engineering & Construction Company to engineer, procure and deliver a wastewater treatment plant for Dolphin Energy's natural gas production and processing facilities in Ras Laffan, Qatar.

The wastewater treatment facility will provide quality water for reuse, reducing both the volume of wastewater currently being injected into the existing re-injection wells at the Ras Laffan gas plant, and the volume of desalinated water purchased from external sources. Kinetic Hydrate Inhibitor (KHI) polymers will also be eliminated from the residual wastewater. Start-up is scheduled for September 2017.

Industry regulators in Qatar have concluded that the presence of KHI polymers in the injected wastewater leads to long term reservoir damage, which is why it is essential to remove them from re-injected wastewater streams. Veolia was awarded a contract in 2015 for its proven HPD® evaporators which will be used for KHI removal and distillate recovery. With this new contract, Veolia will also provide a pretreatment package upstream of the evaporators using its MPP Tilted Plate Flotation technology.

Thierry Froment, Chief Operating Officer for Veolia Water Technologies in the Middle East, said: “Veolia has a rich history in Qatar supported by the development of a number of important projects, including one of the main treatment plants in Doha. We look forward to working again with Qatar Engineering & Construction Company to deliver this project for Dolphin Energy.”

Ras Laffan is an industrial town about 80 km from Doha, which economy is focused on the production of liquefied natural gas. The Dolphin Energy project is one of the largest cross-border energy projects ever undertaken in the Middle East. The goal is to provide natural gas from Qatar through pipeline to meet the United Arab Emirates’ energy needs. Qatar, Oman and the UAE are involved in this project.

Veolia is already involved in a number of operations in Qatar, of which the design, build and operation of the Doha South Wastewater Treatment Plant and the implementation of a “Zero Liquid Discharge” process at Shell’s Pearl Gas-to-Liquid complex in Ras Laffan.
