When you correctly implement the VDU as a linked unit operation to the Atmospheric Residue (AR) stream, you can predict the Conradson Carbon Residue (CCR) in the Vacuum Gas Oil (VGO). For an FCC unit, reducing CCR from 1.2wt% to 0.8wt% via better VDU operation increases catalyst life by 40%.
: Perform case studies and evaluate refinery profit margins for steady-state simulations.
The course represents a specialized training module aimed at process engineers and students looking to master modeling, simulation, and optimization for refinery unit operations using Aspen HYSYS Petroleum Refining . This course, often delivered through AspenTech Customer Education , is designed to provide hands-on experience in modeling complex refining processes, such as atmospheric distillation, vacuum units, catalytic reformers, and cracking units.
The primary goal is to teach users how to build, troubleshoot, and optimize steady-state simulations of refinery processes. Key outcomes include: Refinery Reactor Modeling EHY2102 Aspen HYSYS Petroleum Refining...Unit O...
has long been the gold standard for upstream and midstream oil & gas simulation. However, with the specialized training course EHY2102 (often titled “Aspen HYSYS for Petroleum Refining” or a similar variant), engineers move beyond simple gas plants into the complex world of vacuum distillation, catalytic cracking, and hydrotreating.
Always initialize your VDU column at atmospheric pressure with high reflux ratios, then ramp down pressure incrementally. HYSYS will crash if you start at 50 mmHg from cold.
The most complex piece of equipment a refiner will ever model is the atmospheric crude distillation column—the primary unit that fractionates crude oil into its various components. The EHY2102 course provides extensive, in-depth coverage of this operation through rigorous workshops that guide participants through constructing, converging, analyzing, and manipulating a fully functional atmospheric crude column in the simulation environment. This includes adding essential column auxiliary systems such as: When you correctly implement the VDU as a
The VDU takes reduced crude (atmospheric bottoms) and separates LVGO, HVGO, and vacuum residue. emphasizes:
The course is a professional training program designed to teach users how to build, evaluate, and optimize comprehensive refinery models.
The CDU is modeled using a complex fractionation column equipped with side-strippers, pump-arounds, and steam injection. HYSYS tracks how changes in the column's reflux ratio alter the distillation cut-points for naphtha, kerosene, and atmospheric gas oil (AGO). Vacuum Distillation Unit (VDU) The course represents a specialized training module aimed
By equipping engineers with the skills to master this powerful software, the course provides the key to unlocking higher efficiency, lower operational costs, and a truly competitive edge in the modern petroleum industry.
