Membranes in Water Reuse in Petrochemical and Refining Facilities

This presentation will include a brief discussion of water membrane technologies and their applications in the petrochemical and refining industries, a survey of worldwide membrane installations for wastewater treatment and reclamation in petrochemical plants and refineries; and three representative case studies of using membrane technologies at these facilities. Traditionally membrane processes have been used as pretreatment for ion exchange deionization system to produce purified water for boil feed and process water. The use of membrane processes for in-plant water reuse in the petro industries started in the year 2000 and currently there are approximately 30 reported installations worldwide. Many new petro projects are incoporating water reuse using membrane technologies. The case studies will cover water reuse projects in both petrochemical plants and refineries.
