Abstract

This study presents the evaluation of the cooling tower operational parameters at the Indorama Eleme Petrochemical Company Limited fertilizer plant, utilizing operational data and various cooling tower performance analysis equations that are modeled in MATLAB to determine the cooling tower efficiency, head-load, tower effectiveness and cooling tower range for an in- depth evaluation of the cooling tower. The study yielded numerical results across various parameters. Operational parameters, including inlet and outlet water temperatures, wet-bulb temperatures, were measured to analyze the cooling tower effectiveness. The cooling range increased from 9°C at an inlet water temperature of 36°C and outlet water temperature of 27°C to 13°C at an inlet water temperature of 52°C and outlet water temperature of 39°C aligning with thermodynamic principles. Simultaneously, the cooling approach decreases from 4°C to 3°C with a rise in wet-bulb temperature, indicating improved heat transfer efficiency. As the cycle of concentration increased from 2 to 10, blow-down rate decreases from 95.70 m3/h to 15.80 m3/h, suggesting water conservation benefits. Cooling efficiency, influenced by inlet water temperature and liquid to gas ratio, improves from 65% to 71% as temperatures rise from 36°C to 52°C and the ratio decreases from 1.4 to 0.97. These findings offer valuable insights into optimizing cooling tower operations, emphasizing resource conservation and sustainability. In conclusion, the study provides a nuanced understanding of the cooling tower performance, offering practical implications for operational enhancements and resource efficiency.
