A) Too much make-up stream B) The separator temperature is too high, causing complete vaporization of the recycle C) The compressor is too small D) Your tear stream tolerance is set too high Introduction: What is the Aspen HYSYS User Certification

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. Sample Question 2: Unit Operation Logic Scenario: You have a high-pressure liquid stream at 50 bar. You need to reduce the pressure to 5 bar for a downstream flash drum. The fluid is mostly propane with some dissolved methane. The valve will likely experience two-phase flow downstream. Which HYSYS object is correct? C) Generate pseudo-components (hypotheticals) from the curve
