Your questions are:
1. it possible to do a complete pinch analysis and generate heat exchanger network Proposals Automatically With Aspen Energy Analyzer?
Answer: YES
2. How will the program handle phase Changes? Do you have to undergo evaporation That streams split into three separate streams - one for the heating of the liquid, the boiling for one and one for the superheating part? If so, how do you specify an infinite MCp value at the same time as the enthalpy change is equal to the enthalpy of vaporization?
This question is illogical and makes no sense.
