Track properties like RON (Research Octane Number) , Pour Point , and Flash Point throughout the flowsheet. Conclusion
Most engineers fix pressure. In EHY2102, you learn to optimize pressure . Lowering the pressure in a distillation column reduces the boiling point, saving reboiler duty—but it increases column diameter (CAPEX). Students run trade-off analyses to find the economic optimum.

By adopting EHY2102 and Aspen Hysys, refineries can unlock their full potential and remain competitive in an increasingly complex and challenging industry.
Techniques for building and calibrating FCC reactor models to predict yields based on catalyst and feed conditions. Track properties like RON (Research Octane Number) ,
The course or module code , coupled with the phrase "Petroleum Refining Unit O," typically refers to an intermediate-to-advanced training program focusing on a specific downstream processing block. "Unit O" often denotes the Olefins Conversion Unit (OCU) , the Oxygenate Removal Unit , or in some refineries, the Crude Distillation Unit (CDU) Section O (Overhead) . This article dissects the core competencies expected in EHY2102, providing a step-by-step approach to simulating a representative "Unit O" (focusing on an Olefins/Alkylation preprocessing unit) within Aspen HYSYS.
The core of the course involves building rigorous steady-state models for key refinery units: Lowering the pressure in a distillation column reduces
: Designing atmospheric columns that serve as the first—and most critical—processing step in any refinery. Profit Evaluation
This training is primarily intended for process engineers in design, operations, and technical support roles who are involved in refinery projects, process studies, and plant performance evaluation. It is specifically designed for professionals who need to move beyond basic simulation to model the complex interactions of refining operations, such as engineers working with crude distillation units (CDUs), FCCs, catalytic reformers, hydrotreaters, and other key process units.
