ABSTRACT
This research work is on Design and building of a small shell and tube heat exchanger using algorithm. A heat exchanger is a device which is used to transfer thermal energy between two or more fluid. This project is mainly focusing on designing one type of a heat exchanger which is shell and tube heat exchanger. In this project a fixed tube plate type shell and tube heat exchangers was chosen, exchanger of 150000 lb per hour of kerosene that will be heated from 75 to 120°F by cooling a gasoline stream from 160 to 120°F at a calculated heat load of 3240000. The specification of the Heat exchanger as well as the detailed mechanical design was calculated. It is established that the heat exchanger with gasoline at the shell side and kerosene at the tube side is adequate for the operation. The available area obtained from the calculation is 2105ft2 and also the overall heat transfer coefficient obtained is Btu h -1 ft -2 °F-1 with a LMTD of 42.75°F. It is also seen that the heat exchanger is satisfactory and consist of 6 tube passes with tube outside diameter of 14 (BWG) and length of 24mm,the shell outside diameter of 803.4mm and thickness of 3.72mm. The material for construction for the shell side is carbon steel
