ANALYZING TEMPERATURE CROSSOVER AND SOLVING PRACTICE IN SPIRAL WOUND HEAT EXCHANGERS
This paper proposed a solution of temperature crossover in the spiral wound heat exchanger based on an engineering practice case.By analyzing temperature-heat duty composite curve,it's found that there exists a temperature crossover in a spiral wound heat exchanger.It's supposed to modify the process flow parameter to have reasonable temperature approach,and then present a combination scheme by analyzing heat exchanger network combining with the manufacturability feature of different stream entry at the same height in steel pressure vessels.In brief,it needed temperature-heat duty composite curve analyzing,heat exchanger network analyzing,the material selection of equipment and road transportation factors to design spiral wound heat exchanger.
