Using thermal or catalytic cracking to break large hydrocarbon molecules into smaller, more valuable products. Refining Short-Cut Column: Simplifying the initial distillation modeling process. Optimization:
is an official intermediate-level training course designed by AspenTech to teach engineers how to model, optimize, and troubleshoot complex refinery unit operations. Modern petroleum refineries must constantly balance shifting crude feedstock qualities with volatile market demands for end products. To maintain profitability, engineers rely on the Aspen HYSYS Petroleum Refining simulation environment.
Adding realistic tray, packing, and stripping data to ensure the simulation matches real plant data. 3. Downstream Processing Units
Add pump-around circuits to control the internal reflux and optimize heat recovery. 3. Conversion Units
The sun was setting over the vast industrial complex of the El Riyad Refinery, one of the largest in the Middle East. The refinery's control room, a hive of activity just hours before, was now quiet, with only a few engineers on duty. Among them was Fahad, a process engineer responsible for ensuring the smooth operation of the refinery's hydrotreating unit. ehy2102 aspen hysys petroleum refiningunit o
The course provides deep dives into the primary separation unit of the refinery.
Building crude columns with side strippers and pump-arounds.
Preparing model data to be readable by Aspen PIMS (Process Industry Modeling System) for refinery planning. Key Unit Operations Covered
Before any unit operation can be simulated, the crude oil must be accurately characterized. Petroleum is a complex mixture of thousands of hydrocarbon molecules, making standard component modeling impossible. Using thermal or catalytic cracking to break large
Here is your complete guide to , focusing on process modeling and unit operations. 🎯 Course Overview & Objectives
The primary training module for mastering this platform is the official AspenTech Customer Education course, EHY2102 ("Aspen HYSYS Petroleum Refining: Process Modeling and Optimization for Refinery Unit Operations"). This specialized curriculum bridges foundational chemical engineering principles with rigorous kinetic and thermodynamic refinery calculations. Core Foundations of Refinery Modeling
One of the most powerful tools highlighted in EHY2102 is the tool. Engineers use this to see how changing the furnace outlet temperature or the column pressure affects the "bottom of the barrel" yield. By manipulating these variables in the Hysys environment, you can find the "sweet spot" for profitability without risking a physical plant upset. Common Challenges in EHY2102 Simulations
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. and plant performance evaluation.
