SUPERVISED BY Prof. Adil A. Khan WORK PLACE Charisma Careers Pvt. Ltd. Akota, Vadodara. ABSTRACT The Shell and Tube Heat Exchangers are most commonly used in industries. The shell-and-tube heat exchanger which is the majority type of liquid-to-liquid heat exchanger is used as feed water cooler in process industries, refineries, chemical plants and power plants. It is necessary to operate heat exchanger at optimum condition which serves high thermal efficiency in allowable condition and low running cost. This research is about Shell and tube heat exchangers optimal thermal design, construction and performance. In practical applications pressure drop due to fouling in heat exchanger is the major factor which directly affects the performance of the heat exchanger. The optimal values of pressure drop at various mass flow rates and related heat transfer with respect to fouling factor in heat exchanger, with trial and error method optimal performance condition is estimated. The effect of mass flow rate and fouling variation on other thermal parameters such as overall heat transfer coefficient, fouled heat transfer coefficient, film heat transfer coefficient, heat exchanged and over design is analyzed. Efficient Thermal Design is achieved by controlling fouling amount and pressure drop in operating limits. In this dissertation attempt is made to overcome some major theoretical assumptions and serve practical approach as much as possible for shell tube heat exchanger design and optimization. Number of iteration and their comparisons as well sd analysis is performed in software. The cause of minor error is theoretical assumptions made in manual calculations. The final results are helpful to run shell and tube heat exchanger water cooler at optimal flow pressure drop and fouled condition. View publication stats
