I'm doing some research/lab analysis on methane. Is methane considered a supercritical fluid/gas at 3500 psig and 176 deg F?
Critical point is about -116 deg F and 673 psia.
I have a solution at 447 psig and 100 deg. F. I want to find the latent heat of vaporization using Aspen Plus (an old version). I input the feed stream at pressure and temp stated above and flashed it across a "Flash2" box setting the output parameters of 100 deg F and a vapor fraction of...
