Dhabi’s privately held Dolphin Energy Ltd., through a contractor, has let a contract to a subsidiary of Veolia Environnement SA, Paris, for a new wastewater treatment plant at its natural gas production and processing operations in Ras Laffan, Qatar, about 80 km from Doha.
As part of the contract, Veolia Water Technologies will engineering, procurement, and delivery of a treatment plant designed to supply quality water for reuse in an effort to reduce both the volume of wastewater currently being injected into existing reinjection wells at the Ras Laffan gas plant as well as the volume of desalinated water purchased from external sources, Veolia said.
Scheduled for startup in September 2017, the plant also will be equipped to eliminate kinetic hydrate inhibitor (KHI) polymers from residual wastewater in accord with Qatari industry regulators’ conclusion that presence of KHI polymers in reinjected wastewater streams causes long-term reservoir damage, the service company said.
While Veolia did not disclose a value of the current contract, the company confirmed reception of a previous contract award from Dolphin Energy in 2015 for its proprietary HPD evaporators, which will be used for KHI removal and distillate recovery.
In conjunction with the current contract, however, Veolia said it additionally will provide a pretreatment package upstream of the evaporators using its proprietary MPP Tilted Plate Flotation technology.
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 to be executed in the Middle East,
Since achieving full throughput in February 2008, Dolphin Energy’s Ras Laffan gas project has delivered 2 billion scfd of natural gas via a system of pipelines to the United Arab Emirates (UAE) and Oman, meeting 30% of the UAE’s overall energy requirements (OGJ Online, May 7, 2010; Nov. 6, 2008).
