Master Refinery Simulations with Aspen HYSYS (EHY2102) For process engineers in the oil and gas sector, mastering Aspen HYSYS Petroleum Refining is a major career milestone. The specialized course EHY2102: Aspen HYSYS Petroleum Refining: Process Modeling and Optimization for Refinery Unit Operations provides the deep-dive training needed to build and manage complex refinery models. What is EHY2102?

C. Using the Adjust Operation

For pumparound duties: use an Adjust operation to vary pump-around flow until the desired temperature drop (AT) is achieved. EHY2102 Aspen HYSYS Petroleum Refining...Unit O...

1. Run an initial flash at feed T,P to separate H2 and light gases. Adjust feed to column only liquid/vapor appropriate fractions.
2. Build RadFrac with 30 stages; place side draw for heavy product at stage 28 and mid draw at stage 15.
3. Start with fixed product splits (10/60/30) and adjust reflux ratio to achieve required mid-cut composition.
4. After convergence, switch to specification by product boiling point or recovery to reach final product specs.
5. Evaluate mass balance: check that H2 slip is consistent; ensure heat duties are reasonable (reboiler duty estimate vs expected steam availability).
6. Perform sensitivity on reflux ratio and feed stage location to optimize energy vs separation.

The primary goal of EHY2102 is to teach users how to simulate a full refinery flowsheet while maintaining the integrity of petroleum properties throughout the process. Master Refinery Simulations with Aspen HYSYS (EHY2102) For

Whether you are optimizing an atmospheric column or designing a new vacuum unit, the tools found in this module ensure that your simulation matches the complexities of the real world. Run an initial flash at feed T,P to
