Requires building or modifying a simulation model in a live cloud-based Aspen HYSYS environment. Candidates must perform specific tasks—such as gas stream simulation—and answer technical questions based on the results. Key Exam Topics
Candidates are tested on their ability to navigate the interface, build simulations, and troubleshoot models. Key topics include: Aspen HYSYS User Certification Exam aspen hysys user certification exam 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.

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? Key topics include: Aspen HYSYS User Certification Exam
