Deterioration of the filling material in traditional cooling towers is of serious concern. In this study, cooling towers of Arvand and Boualisia Petrochemical plants in the South of Iran are used as the filling material. The size of the cooling towers and outlet conditions are measured in a real situation and compared with heat and mass transfer correlations by modeling the towers and then calculating the tower heights. An experimental study to model the heat and mass balance equations and their relationship by tower height is conducted. The previous correlations found in the literature did not predict the relationship between these equations and tower height for the tested towers. A new formula by supplying the numerical methods was developed, and new variables defined. This correlation can predict the height of tower within an error of ±10%. The developed correlation is used along with theoretical modeling to predict the cooling tower outlet conditions within an error of ±5%.

Key words: Cooling tower, modeling, mass transfer coefficient, tower height.
