Abstract:
Heat exchangers are the equipment used in industrial processes to recover heat between two process fluids. They are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, and natural gas processing. A common problem in industries is to extract maximum heat from a utility stream coming out of process, and to heat cold fluid. The present work is based on industrial requirement. In the petroleum refinery after distillation different grade of oil comes out at different high temperature which comes in to a pump and supplied at required level. The heat recovered from high temperature hydrocarbons is utilized to increase the temperature of crude oil up to required limit. The heat exchanger data, temperature of hydrocarbon and required temperature rise of crude oil were Chosen. Therefore the objective of present work involves the study of refinery process and apply phenomena of heat transfer for steel material and different thickness for thermal design procedure of the counter flow heat exchanger. The inner pipe in which hot hydrocarbon flows and in outer annulus cold crude oil passes from opposite direction. The heat recovery from hot fluid is used to increase the temperature of cold fluid. Design was carried out based on the outlet temperature requirement of the cold fluid. With the help of computation fluid dynamics the study and unsteady simulation carried out for designed heat exchanger and based on the simulation results thermal analysis carried out.
