: Delayed Coker, Visbreaker, Naphtha Hydrotreater, and Alkylation units. Operational Tools : Using the Petroleum Feeder to supply crude to the flowsheet and the Product Blender for final product optimization. Planning Integration : Generating delta vectors and updating Aspen PIMS refinery planning models. Key Learning Outcomes
Are you ready to optimize your Unit Operations? Review your Aspen HYSYS Petroleum Refining license and ensure the "Reactor" and "Tray Rating" add-ons are active.
The allows for the modification or "manipulation" of existing crude assays to test scenarios such as "what if the API gravity of the crude decreases?" It allows for the adjustment of cut points and properties, crucial for optimizing the feed to a refining unit. 3. Refining Short-Cut Column

You should have a basic familiarity with process simulation. It is recommended that you either have extended experience using Aspen HYSYS or have previously completed the introductory course EHY101: Aspen HYSYS Process Modeling .
: For final product specification and value analysis.
Below is a guide to the core modules and unit operations typically covered in this course curriculum. 1. Assay Characterization & Management Key Learning Outcomes Are you ready to optimize
Set up feed stream(s)
is the definitive training curriculum developed by AspenTech Customer Education to equip engineers with the skills required to simulate, troubleshoot, and optimize complex downstream facilities. In modern oil refining, operators face immense pressure to adapt to shifting feedstock qualities, minimize emissions, and preserve tight profit margins. This professional-grade technical article provides a comprehensive deep dive into the core components, unit operations, and advanced capabilities taught within the EHY2102 framework. The Core Blueprint of EHY2102
: Conduct case studies to determine the most profitable operating points. In modern oil refining
Assumptions: Unit O is a three-product fractionator (light, mid, heavy) receiving a heated reactor effluent. Pressure is moderate (5–15 bar), temperature range across the column 40–350°C.
The foundation of any good refinery model is the assay. Unit O allows you to blend different crude oils to see how they interact. This is vital for refineries that switch feedstocks based on market prices. You can predict the yield of each cut (Light Naphtha, Heavy Naphtha, etc.) before the crude even hits the furnace.
