Severn Trent Serves Oil Refinery in Pakistan
Severn Trent Services recently provided multiple water treatment technologies, including reverse osmosis and electrodeionization (RO/EDI) systems, for Bosicor Oil Pakistan Limited, a private sector crude oil refinery under construction in Pakistan, which will have a capacity of 115,000 bpd and will be the largest crude oil refinery on completion (3Q 2010).
Bosicor Pakistan Limited, an associated company of the refinery under construction, is already in the business of crude oil refining. The existing and proposed refineries are located at MuazaKund, Hub, Balochistan, Pakistan. The complex RO/EDI system, which will purify seawater for use as process water at the refinery, includes a UAT reverse osmosis membrane filtration system and a UAT EDI system from Severn Trent Services and also incorporates a dissolved air flotation system (DAF). The RO/EDI system will purify the refinery’s process water at a rate of up to 4.0 mgd.
Bosicor Oil Pakistan Limited required a total solution that incorporated multiple technologies in order to treat open seawater up to 40,000 ppm of total dissolved solids. The double pass RO/EDI system provided by Severn Trent Services combines reverse osmosis and electrodeionization technologies to effectively remove more than 97 percent of all feedwater contaminants, including ionic, organic and particulate contamination from cooling water intake. The system consistently produces a very high water quality effluent, which is ideally suited to produce the refinery’s required water purity of ≤ 0.2 microsiemens. Severn Trent Services is responsible for supplying, testing and commissioning their manufactured system.
According to Marwan Nesicolaci, vice president of international sales and business development for Severn Trent Services, “The RO/EDI system is the first filtration system of its kind in Pakistan, and the system’s design and low energy costs make it an excellent choice for industrial ultrapure water applications.”
