Abstract:
Inappropriate performance of the air-cooled condensers in the process industry will make the flow out of the air cooler not fully condensate and its pressure is greater than the design value. This will lead to product loss and safety issues. In this study, factors affecting the performance of air cooler and various solutions to solve these problems have been identified. As a case study, the first distillation tower of the Ali Siana Petrochemical Complex, which disrupts its function in some months of the year, has been investigated. Aspen Hysys process simulation software simulates the naphtha splitter unit and the Aspen Exchangers Design & Rating software simulates the air cooled condesor and study the various practical solutions. Finally, it has been suggested a series of recomendation. Installation of water coolers in the distillation tower overhead flow, the use of detergent in periodic cleaning, the use of magnetic filters to improve feed quality, and to reduce the pressure of the tower and the simultaneous use of the water cooler
