请问一下，为什么运行之后就出现错误（附件中有aspen流程）Block: P2    Model: PUMP  **  ERROR WHILE GENERATING RESULTS FOR UNIT OPERATIONS BLOCK: "P2" (MODEL:
   "PUMP")
   BUBBLE POINT CALCULATIONS CANNOT BE PERFORMED BECAUSE THE SPECIFIED
   TEMPERATURE IS ABOVE THE CRITICAL TEMPERATURE. VAPOR PRESSURE CALCULATION
   FAILED TO CONVERGE. NPSH AVAILABLE IS UNRELIABLE.

不收敛啊，好像不是泵的问题，是三进三出换热器的问题！

应该是条件有问题

应该是一定压力下，泵的进料温度的问题吧，可以试试
