I am currently working on a project in which there is an INLET stream (100% Nitrogen) at 25C and 250bar. I want to depressurize it using Turbine/Expander model in Aspen Hysys and bring it down to 40bar. I have performed the steady analysis and want to perform the dynamic analysis i-e want to observer the decrease in temperature after few seconds. Switching to dynamic mode, after performing steady analysis, I have created a strip chart to observe the decrease in Temperature due to gas expansion. But strip chart is only showing me the steady state outlet temperature all the time.
Can I observe the decrease in the temperature graph from 25C to whatever it achieves after reaching steady state?
NOTE: flow sheet is simple. An inlet stream, followed by an Expander and the outlet stream.
