【 摘 要 】

References(8)Cited-By(2)Presented is a method for fundamental analyses and heat integration of process systems at cryogenic temperature by using a heat availability diagram which is constructed by plotting a temperature function (1-T0/T) against heat load Q, based on available energy concept of thermodynamics. The function takes values between unity and minus infinity. By using the diagram, heat availability and available energy loss in a process system at cryogenic temperature are thoroughly analyzed, and the maximum theoretical rate of heat recovery is determined. A series of bottlenecks in heat recovery are sequentially found, and modified heat recovery systems are evolved.
