Modularized HPD® Evaporation and Crystallization system for Dolphin Energy

Modularized HPD® Evaporation and Crystallization system for Dolphin Energy

Veolia Water Technologies will engineer, procure and deliver an industrial wastewater management system including its proven HPD® Evaporators used for KHI removal and distillate recovery at Dolphin Energy’s natural gas production and processing facilities in Ras Laffan, Qatar.

The current project is a culmination of multiple years of development between Veolia and Dolphin Energy Limited. In 2012, Dolphin Energy awarded Veolia a research and development study to evaluate a wide range of water treatment technologies for treating produced water that contains Kinetic Hydrate Inhibitor (KHI). Dolphin Energy’s initiative was prompted by a move to eliminate discharge to KHI wastewaters from their onshore gas processing facility in Qatar.

Through its research and development study, Veolia identified evaporation as a feasible process to treat KHI laden wastewaters and generate a recovered water stream free of KHI. Soon after the study results were reported, Dolphin Energy initiated a Tender Process for supply of the industrial system to treat their KHI wastewaters at Ras Laffan Industrial City. In April 2015, after nearly three years of collaborative interactions, Veolia won the competitive bid to supply the industrial solution.

Veolia’s system will be divided into two steps of evaporation: the first step is driven through Mechanical Vapour Recompression (MVR) and the second step driven through Low-Pressure (LP) steam. For both steps, forced circulation technology was selected due to the viscous nature of the concentrated organic wastewater. In order to further enhance the process distillate quality, vapour washers will also be included at the MVR.

The plant will have a capacity of 40 m3/hr and start-up is scheduled in September of 2017. Dolphin Energy´s onshore gas facility will rely on the high mechanical availability of Veolia´s system to maintain gas extraction operations during KHI injection (seasonally November through May of each year).

About Dolphin Energy

The Dolphin Gas Project of Dolphin Energy Limited is a major regional strategic energy initiative. Since July 2007, the company has been producing, processing and supplying substantial quantities of natural gas from offshore Qatar to the United Arab Emirates.

Production reached the maximum authorized throughput of 2 billion standard cubic feet of gas per day (scf/day) in February 2008. Gas supply to Oman began in October 2008.

The overall investment in constructing the entire Dolphin Gas Project has made it one of the largest energy-related ventures ever undertaken in the Middle East at a cost of USD$5.8 billion.

Dolphin Energy Limited is owned 51 percent by Mubadala Development Company, on behalf of the Government of Abu Dhabi – and 24.5 percent each by Total of France and Occidental Petroleum of the USA.
