This article provides a comprehensive analysis of what the EHY2102 workflow entails, how it applies to critical refining units, and why mastering this simulation is the fastest path to reducing opex (operational expenditure) by 15-22% in a medium conversion refinery.
: 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
A properly converged CDU Unit O in Aspen HYSYS will predict the True Boiling Point (TBP) curve of the Heavy Naphtha with an error margin of less than 1.5°C. This accuracy determines whether your downstream catalytic reformer (Unit R) has enough feed or cokes out prematurely.
In the world of high-stakes chemical engineering, is the code for a specialized training mission: EHY2102 Aspen HYSYS Petroleum Refining...Unit O...
This is where truly shines. You will learn to simulate:
Study of various petroleum refining processes such as distillation, cracking (e.g., FCC, hydrocracking), reforming, and hydrotreating.
Using Aspen HYSYS for optimizing process conditions to improve yield, efficiency, and profitability of refining operations. This article provides a comprehensive analysis of what
To succeed in EHY2102, participants typically need a background in chemical or process engineering and a functional knowledge of Aspen HYSYS. It is strongly recommended that attendees have either completed the course or have equivalent experience in building and navigating steady-state simulations.
: Identifying bottlenecks in Crude Distillation Units (CDU) and evaluating the impact of feedstock changes. Key Unit Operations Covered
According to the Aspen HYSYS Petroleum Refining Reference Guide , the following specialized units are typically covered: Planning Integration : Generating delta vectors and updating
Refineries process crude into product streams via a train of separation, conversion, and treatment units. Typical units include:
While the atmospheric column is a cornerstone, a modern refinery consists of dozens of interconnected unit operations. The EHY2102 course has been specifically designed as a comprehensive course, covering a wide array of these critical units that make up the rest of the plant. Its curriculum includes a deep dive into key unit operations, such as:
Before crude enters the CDU furnace, it passes through a series of heat exchangers known as the preheat train.
