Configuring unit operations (heaters, coolers, pumps, compressors, and valves).
The Aspen HYSYS Certification program, often taken through AspenTech University , assesses an individual’s practical skills in building, troubleshooting, and optimizing simulations. The is a common target for professionals, testing high-level proficiency. Exam Overview (as of 2026):
A mix of multiple-choice, true/false, and hands-on performance-based questions where you must interact with a live or simulated HYSYS environment. Duration: Typically 2 to 3 hours. Passing Score: Generally 70% or higher. What happens to the vapor fraction if the
Selecting the correct thermodynamic package (e.g., Peng-Robinson, SRK, NRTL) based on the components (hydrocarbons vs. polar compounds).
Describe steps to set up a simple flash calculation to separate a vapor and liquid at a specified pressure:
Which fluid package is most suitable for this simulation? B) Peng-Robinson D) UNIQUAC D) Vapor fraction becomes zero
By understanding these core concepts and practicing with sample scenarios, you can confidently prepare for the Aspen HYSYS User Certification exam and advance your career in process simulation.
Choosing the right property package is the foundation of any accurate simulation. Expect questions on: Selecting property packages (e.g., Peng-Robinson vs. NRTL). Managing components and adding hypothetical components.
Open-book (you usually have access to Aspen HYSYS and its help files during the test). Passing Score: Generally 70% or higher. Core Topics Tested 1. Fluid Packages and Thermodynamics
