Abstract

Heat transfer between two streams is common, well established and perfectly commercialized. Normally, the exchanger that is intended for this purpose is shell and tube but in some industrial applications we have more than one reactant which are to be preheated or pre-cooled for chemical reaction and same as post heating and post cooling required of multiple streams at same or different temperatures, Problem that is associated with the shell and tube heat exchanger is that it can’t handle the multiple streams and for handling multiple streams we required more number of exchangers due to which capital cost increases and required more care of handling. To overcome this problem, we need more than one heat sinks with one or more than one heat source that will minimize the covered volume per unit heat transfer area, the number of unit operation, operation time, man power and the capital cost with increasing thermal efficiency and heat utilization so to overcome this problem we need to move towards multi stream heat exchanger. Multi stream heat exchanger is opening of a new class of heat transfer equipment which deals more than two different streams for heat exchange. Such a way number of units can be reduced, which minimize time and space. With a little bit increase in complexity the operational cost will decrease and improve the thermal efficiency of heat transfer equipment, which minimize thermal losses and maximize the heat utilization. The present study involves the Comparative Study of Floating Head (Triple pipe) Multi Stream Heat Exchanger with Shell & Tube Heat Exchanger, where we calculate experimentally the heat duties of both fluids, effectiveness and fractional heat transfer and compare the results to prove that by using The Floating Head Multi-Stream (Triple Pipe) Heat Exchanger number of units can be reduced, which minimize operational cost, time, space and thermal efficiency will be improved.
