Ehy2102 Aspen - Hysys Petroleum Refiningunit O

EHY2102 (Aspen HYSYS Petroleum Refining: Process Modeling and Optimization) is an intermediate course by AspenTech esupport.aspentech.com/UniversityCourse?Id=a3p0B0000004YmvQAE teaching engineers how to simulate and troubleshoot refining units. It covers petroleum assays, distillation modeling, and reactor modeling for FCC, reformers, and hydrocrackers, focusing on optimizing operating points.

For the heavier bottoms of the atmospheric tower, the Vacuum Unit is simulated to recover vacuum gas oils (VGO) for downstream cracking. HYSYS helps engineers determine the optimal vacuum pressure to maximize recovery without "cracking" the oil prematurely in the furnace.

Assay Manipulators & Blenders: Tools like the Petroleum Feeder and Product Blender allow for the realistic mixing of different crude streams and the manipulation of their properties to match plant data. 2. Modeling Rigorous Refinery Reactors Input assay data (distillation curves: TBP, ASTM D86,

• Input assay data (distillation curves: TBP, ASTM D86, light ends composition).
• Cut the crude into pseudo-components (hypothetical components with defined boiling points and densities).
• Select the correct property package. For vacuum towers, the Peng-Robinson equation of state is standard; for amine treating, Electrolyte NRTL is used; for crude towers, GS (Grayson-Streed) or PR with volume translation.
