Heat exchangers are one of the most common process equipments in the process industry with much more significance nowadays due to the importance of energy saving and optimization. The shell and tube type accounts for the majority of the exchangers in use. Changes in processing conditions necessitate prediction of new situations that may arise which is only possible through reliable modeling and simulation procedures. In the present work two separate models (a plug flow model and a cross flow model) were developed. Pressure drop and flow analysis calculations were carried out using Willis and Johnson method for the shell side while tube side process drop was evaluated using the Bell method. Based on these calculation methods a combined model with different combination from the two base models was developed to provide a more real prediction. The simulation results were checked against experimentation taken place at Delaware University and about ±10% error was recorded.
