This one was a bit trickier. I recalled that Aspen Hysys often uses the Peng-Robinson equation of state for non-ideal mixtures, but I also knew that the Wilson and NRTL activity coefficient models are commonly used. I decided to go with answer D) NRTL activity coefficient model. Consists of approximately 65 multiple-choice questions

Natural gas mixtures at high pressure require an equation of state that handles non-ideal vapor-liquid equilibrium (VLE) at cryogenic temperatures. Peng-Robinson (PR) is the industry standard for hydrocarbons. NRTL is for polar/non-ideal liquids. STEAM-TA is for water/steam only. AMINES is for sour gas sweetening specifically.
