Hi everyone
I Have a problem with aspen hydraulics. For those who do not know, this is the pressure drop calculation in Hysys 8.8.
context: checking of a steam network (saturated pressure, thermopackage is ASME)
My problem is simple: the inlet stream is vapor @saturated conditions. the inlet stream in the aspen hydraulics block is liquid at the same conditions.
Why? My guess is the thermo package is not the same in hysys en aspen hydraulics. How can i change it? Also, i can change the transition basis from T-P flash to P-H flash which gives me vapor but not the same temperature.
I don't know what to do?
Thank you all
