Veolia Water Technologies has been selected by the HDGSK Joint Venture to supply a Zero Liquid Discharge Evaporator and Crystallizer for the Karbala Refinery Project in Iraq.

Iraq´s State Company for Oil Projects (SCOP) and their EPC contractor HDGSK, a joint venture composed of Hyundai Engineering & Construction Co., Ltd., GS Engineering & Construction Co., Ltd., SK Engineering & Construction Co., Ltd., and Hyundai Engineering Co., Ltd., have selected Veolia´s HPD® evaporator technology for the Karbala Refinery project.

Veolia will engineer, procure and deliver a Zero Liquid Discharge system based on its proven HPD® Brine Evaporator and Brine Crystallizer technologies for calcium sulfate seeded slurry processes.

Veolia’s system will be divided into two steps: the first step is a Brine Concentrator based on calcium sulphate seeded slurry and driven through a single Mechanical Vapour Recompression (MVR), and the second step is a Zero Liquid Discharge (ZLD) Brine Crystallizer driven through two stages of single MVR.

The combined system will eliminate all liquid waste discharge and will produce a waste solid product discharge from a centrifugal separation process. Waste solids from the plant will be routed to a landfill for disposal. The process distillate quality recovered from the process will be routed internally to the refinery for reuse.

Ignacio Martinez, Vice-President and General Manager of Veolia Water Technologies’ Evaporation &Crystallization activities, said:

“The Karbala refinery is due to become the most technically advanced refinery in Iraq. Veolia is proud to contribute its strong expertise in zero liquid discharge and waste reduction processes, helping Iraq’s SCOP and the HDGSK joint venture meet their economic and environmental goals.”

The plant will have a capacity of 55 m3/hr and is scheduled for delivery in August 2016. The Karbala Refinery ZLD facility will rely on the high mechanical availability of Veolia´s system to maintain the refinery´s water treatment operations.

The Engineer, Procure and Construct contractor for the Karbala Refinery Project is HDGSK, a South Korean joint venture led by Hyundai Engineering & Construction that won a $6.04 billion project to build oil refining facilities in Karbala, Iraq. The joint venture consists of Hyundai E&C, Hyundai Engineering Co Ltd, GS Engineering & Construction, and SK Engineering & Construction.

Hyundai E&C and affiliate Hyundai Engineering have a combined 37.5 percent stake in the project, worth $2.265 billion. GS also has a 37.5 percent stake, while SK has a 25 percent stake worth $1.51 billion. SK Engineering & Construction is responsible for the water utilities at the refinery and was responsible for selecting Veolia´s Zero Liquid Discharge technology for the project.
