EHY2102: Aspen HYSYS Petroleum Refining: Process Modeling and Optimization for Refinery Unit Operations is an intermediate-level course designed to provide engineers with the skills needed to simulate, evaluate, and optimize complex petroleum refining processes.

1. Conversion Unit: Use a Gibbs Reactor to find the theoretical sulfur removal limit.
2. HYSYS Petroleum Refining Module: Switch to the Hydrotreater Reactor sub-flowsheet. This built-in Unit O contains pre-loaded kinetics for HDS (Hydrodesulfurization), HDN (Hydrodenitrogenation), and HDA (Hydrodearomatization).

• Insert a Quench Point (mixer) between PFR segments.
• Cold H₂ from the recycle compressor is injected.
• Set a controller (HYSYS PID) to maintain interbed temperature <420°C.

By mastering the unit operations detailed in Unit O – from the atmospheric tower’s pumparounds to the catalytic reformer’s recycle compressor – you gain the confidence to tackle any refining simulation challenge. And in an industry where a 1% increase in liquid yield can mean millions of dollars annually, that confidence is priceless. EHY2102 Aspen HYSYS Petroleum Refining...Unit O...
