Abstracts: Our UDP Project is Redesign and Analysis of Shell and Tube Heat exchanger. Shell and Tube Heat Exchangers are used as process heat exchangers in the petroleum-refining and chemical industries. It is used as steam generator, condensers, boiler feed water heater, and oil coolers in power plant, as condensers and evaporators in some air-conditioning and refrigeration applications and also in waste heat recovery applications with heat recovery from liquids and condensing fluids and environmental control. Shell and tube heat exchanger is widely used as a chiller plant. Nowadays every industry is trying to improve the efficiency of the heat exchanger and wants to make it better. Shell and Tube Heat Exchanger that we are working on is fixed Tube-sheet and counter flow type Heat Exchanger. Here, fluid used at Shell side is crude oil and at tube side fluid is ammonia gas. Crude oil is hot fluid while ammonia Gas is cold fluid. We are designing and doing analysis of this heat exchanger due to the problem of Large Pressure Drop at shell side, large Pressure Drop at tube side, Less Heat Transfer rate. So we are designing such kind of heat exchanger which can overcome these things.
