Abstract:
Reviews cases of water and energy losses in cooling towers of oil refineries.
Cooling towers are the equipment to set the temperature cooling water service of integrated oil, gas and petrochemical used. In this equipment, heat and mass transfer occur simultaneously to cool water in the vicinity of air. Hence, the significant transfer of air and water to create moist air from the process cycle casualties is removed. The main goal of this research is to reduce water cost of cooling water system of the oil refinery. Economic principles in order to review the definition of an objective function for a Trade-off between construction cost, installation and operation dry cooling tower and reduce the cost of wet cooling tower make-up water is more. Results obtained from studies in the sample case study objective function, the Tabriz refinery cooling towers were selected, expresses that: There is no economic justification for replacement method, also saving cost in series hybrid method is 171,600.00 US$ per year and in split method is 212,400.00 US US$ per year. Presenting the proposed method based on dry bubble temperature variations during the year can be a combination of two methods used to determine the best route in the cold months of the year (December, January and February) split method and the rest months use series method to the cost saving result is expressed 281,100.00 US$ per year.
