Crude oil refineries and petrochemical complexes require a reliable supply of fresh water for steam generation, process cooling, and other purposes. Since fresh water is becoming a more scarce and valuable resource in many parts of the world, several locations have undertaken programs to reclaim and reuse waste waters for cooling and steam generation. Two case studies are presented which illustrate some of the technical challenges that were encountered when reusing water in refining and petrochemical complexes
