Doha: Qatar Shell GTL Ltd has awarded the design-build contract for the Pearl GTL complex effluent treatment plant at Ras Laffan Industrial City to a consortium formed from a 50/50 joint venture between Veolia Water and Sapem and a local construction company, Al Jaber, the company said.
Optimising management of the water cycle with an objective of zero liquid discharge into the natural environment is a major aspect of the Pearl GTL project. Thus, the plant will be dedicated to the treatment and recycling of industrial effluents from this massive industrial complex.
The Pearl GTL project comprises the development of upstream gas production facilities and an onshore GTL plant that will produce 140,000 barrels per day of GTL products and approximately 120,000 barrels per day of condensate, liquefied petroleum gas and ethane. When completed, it should be the world's largest integrated GTL complex.
Veolia Water Solutions & Technologies will drive the design and completion of the effluent treatment plants supported by patented technologies from its subsidiaries OTV, HPD, Rossmark and Veolia Water STI, offering a unique portfolio of processes.
In particular, wastewater will be treated by ultrafiltration and reverse osmosis, with the objective of their complete reuse within the factory process. Thus, no liquid effluent will be discharged into the natural environment. Sludge treatment will be carried out by evaporation and crystallization, a technology achieving low volumes of de-watered sludge and salt crystals.
"The Pearl GTL contract, based on Veolia Water's expertise in the recycling of industrial effluents, represents the most important design-build contract won by Veolia Water in the Middle East since the seawater desalination plant in Bahrain in April 2006. This new contract confirms the company's position as a supplier of technological solutions for the long term management of water resources through using alternative resources" said Antoine Frrot, Managing Director of Veolia Water.
