Hi,
I am relatively new to the forum and and not a ChemE. I am trying to design and model a system for separation of Real Gas and Air by refrigeration and thus condensing the real gas and venting non condensable gas to second stage and do the same thing there to ultimately exhaust only NCG to atmosphere. The gas mixture is supplied from a ISO tank. I don't know the pressure of the tank. The ambient temperature is 70F. The real gas is condensed at -20F and 20 psig. With this information is there a way I can figure out the molar fraction of Air in the mixture. The mass fraction of air is 10% and Real Fluid is 90%.
Thank you in advance.
