The course entitled “Design of Shell and Tube Heat Exchangers” focuses on the thermal design of Tubular Exchanger Manufacturers Association (TEMA) standard-based Shell and Tube Heat Exchangers. This course starts with applications of heat exchangers in various industries including the process industry. Recommended allowable fluid pressure drops and velocities on the shell side and tube side and their impact on heat exchanger effectiveness and sizing are covered. Front-end stationery head types, shell types, and rear-end head types based on TEMA standard, and the description of some of TEMA configurations citing examples are covered. Shell side and tube side fluid allocation considering case studies are demonstrated. Data required for design and the procedure for tube side design and shell side design are also covered. Types of fouling, its control, the economic penalties associated with fouling, and corrosion monitoring methods are covered in detail. Finally, the thermal design of shell and tube heat exchangers is demonstrated by considering the case studies, such as Liquid-Liquid, Gas-Gas, and Gas-Liquid combinations.
