Aquatech, a global water and wastewater technology provider for the industrial and infrastructure markets, has been awarded a contract to design and supply a multiple effect distillation (MED) seawater desalination system for Orpic’s Sohar Refinery Improvement Project in Oman.
Orpic (Oman Oil Refineries and Petroleum Industries Company) specified MED technology for uninterrupted water supply to boilers and other site needs. The desalination facility will supply pure water to boilers, service water as well as potable water.
Aquatech’s scope of services includes design, equipment supply, testing and commissioning of three MED units, complete with accessories and post treatment systems, to produce distilled water within a challenging schedule as demanded by the project. Aquatech is supplying the system to a Petrofac–Daelim Joint Venture that has the full EPC contract for the whole refinery project.
Expected to be commissioned in early 2016, the system supplied by Aquatech will comprise:
- three Multiple Effect Distillation with Thermal Vapor Compression (MED-TVC) units, each with a net capacity of 5,352 m3/day
- three Fractional Electrodeionization (FEDI) demineralization units, each with a capacity of 3,360 m3/day of ultrapure water for boiler feed
- two remineralization dosing skids for the production of service water and potable water
The desalination facility will treat seawater from the Indian Ocean to produce pure water with less than 5 mg/l of total dissolved solids. Plant steam will be used to provide the energy to operate the desalination units. It is designed for a performance Gain Output Ratio (GOR) of over 6.3. The demineralization system consists of the patented FEDI process and will provide ultra pure water with less than 0.1 ppm of dissolved solids for boiler feed water.
The market for desalination pumps, valves, filters and chemicals will top $5 billion in 2015, according to the McIlvaine Company, aggregating forecasts from several of its reports.
