  7. Abstract:
  8. Water is used as a key material in different processes of chemical industries. Considering abundant demand of chemical industries for water, pollution that threats this valuable material and the fact that there is currently no proper substitute for water, an urgent necessity is felt for economic utilization of water in industrial processes and optimal use of water resources. A variety of methods have been developed for analysis of water consumption in industrial processes, amongst are Pinch methodology and Mathematical Programming approach. In this thesis a Petroleum Refinery has been preferred as a case study in which optimization of water consumption in the aforementioned petroleum refinery had been previously analyzed via Pinch methodology. Accordingly, data concerning water using network of the petroleum refinery were collected and a superstructure model based on the application of mathematical programming approach was developed for this purpose. In the next step, the model was applied by using GAMS software, with the objective of minimization of fresh water using network of the refinery in order to bring a reduction to fresh water consumption rate.. Finally, fresh water consumption rate of the petroleum refinery decreased from 505 m3/h to 320 m3/h (equal to 36.63%) as well as 4% improvement in contrast with the pinch methodology.
