Oil Characterization
This is typically a module found in Chemical Engineering curriculums or professional training certifications (such as those from AspenTech or engineering providers). The "Unit O" likely refers to a specific section within that course, often covering or Petroleum Assay .
Net effect: Highly exothermic. A typical VGO hydrocracker sees an adiabatic temperature rise of 30–70°C across the bed. EHY2102 Aspen HYSYS Petroleum Refining...Unit O...
- Crude Distillation Unit (CDU)
- Vacuum Distillation Unit (VDU)
- Hydrotreating (e.g., diesel, naphtha)
- Fluid Catalytic Cracking (FCC)
- Catalytic Reforming
- Alkylation, Isomerization
- Sulfur recovery (Claus)
Unit O in many course assignments often represents a midstream unit — e.g., a vacuum flash, hydrotreating reactor, or hydrocracker fractionation section. For this post, assume Unit O is a mid-pressure fractionation/splitter downstream of a conversion reactor: it separates reactor effluent into light ends, gasoline-range, and heavier recycle.
