Temperature Distribution Analysis along the Length of Floating Head Multi Stream Heat Exchanger

Heat transfer between two streams is common and simple and well established and perfectly commercialized. Normally, the exchanger that is used for this purpose is shell and tube heat exchanger but in some industrial production unit where more than one reactant is 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 such type shell and tube heat exchanger is that it can’t handle the multiple stream and for handling multiple streams we required more number of exchangers due to which capital cost increases and required more care of handling because the number of units increases. 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 for handling multiple streams at once for heat exchange. 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 which directly decrease the equipment size and capital cost. In the previous study we have discuss our research on the fabrication and Comparative Study of Floating Head (Triple pipe) Multi Stream Heat Exchanger with Shell & Tube This work is about the investigation involves the tentative examination of the heat exchange through the Floating Head Multi-Stream Heat Exchanger to evaluate the temperature distribution along the length, in which cool liquids are flowing through the inner and external pipe and hot liquid is moving through the central pipe of the exchanger.
