Design and Modelling of Shell and Tube Heat Exchanger with Cut Segmental Baffles

The transfer of heat from one fluid to another fluid is an important operation for most of the process in chemical industries by using a heat transfer equipment. The equipment which is used for heat transfer process is generally known as heat exchangers. The heat exchangers are normally classified depending on the transfer process occurring in them. Shell and tube heat exchanger (STHE) the most common type of heat exchanger which is used in Oil refineries. This project work is focused on the study of STHE, their types, design considerations and their modes of failure which were used in Oil refineries in detail. The thermal performance and pressure drop are considered as major factors for the design and evaluation of STHE. The main objective characteristic of Shell and tube heat exchanger design is the procedure for specifying the design of heat exchanger, their heat transfer surface area, pressure drops and checking whether the assumed design satisfies the requirements. The Shell and tube heat exchanger and baffles such as single segmental baffle, double segmental baffle and helical baffle is designed as per ASME Boiler and Pressure Vessel Code, Section VIII and Tubular Exchanger Manufacturers Association (TEMA) standards. The modelling of the designed STHE with various baffles is carried out by using Solid Works software. In this work, the existing model of STHE is designed with different baffles and modelled.
