Keywords: Wastewater minimization, petroleum refinery, water pinch

Because of continuous increase in fresh water cost, as well as wastewater treatment cost due to more stringent environmental laws, the application of process integration approach in wastewater minimization studies is gaining more attention. In this work, a case study on water minimization in a petroleum refinery is presented. Petroleum refineries use water in variety of processes, such as steam stripping, steam ejectors, desalting etc. In this processes, water is in contact with process streams, and is contaminated with pollutants such as H2S, various hydrocarbons, and suspended solids. Water balance was established and water using processes analyzed. Re-use possibilities were identified, and water re-use network synthesized using available tools and methods, such as water-pinch.
