Part 3: Deep Dive – Simulating the Selective Hydrogenation Unit (SHU)
The heart of Unit O is the SHU Reactor. In EHY2102, you will move from a conversion reactor to a kinetic reactor. Optimizing Petroleum Refining with EHY2102 Aspen Hysys
A
- Simulate Current State: Calibrate the Deisobutenizer column using plant data (temperature profile, pressure drops).
- Run Column Internal Analysis: HYSYS reveals that the existing sieve trays have a 60% efficiency, causing excessive entrainment of isobutylene into the bottoms.
- Propose Modification: Switch the column to structured packing (HYSYS Packing Sizing tool – Sulzer Mellapak 250Y).
- Result: Simulation predicts isobutylene recovery increases from 98% to 99.7%. The Economic Analyzer (linked to HYSYS) shows a payback period of 6 months.
Planning Integration: Generating "delta vectors" and data readable by Aspen PIMS for refinery-wide linear programming (LP) planning. 2. Key Technical Components Planning Integration : Generating "delta vectors" and data
6. Advantages & Limitations
✅ Advantages
- Integrated refining-wide simulation (crude to finished products).
- Assay management & blending tools.
- Predicts yields without pilot plant data (using kinetics).
- Energy integration (pinch analysis compatible).
