Created bySarah Zayan
Last updated 5/2025
English

What you'll learn

  • Understand the principles of distillation, including feed characteristics and product specifications.
  • Analyze process flow diagrams (PFDs) and the design of unit equipment like distillation columns.
  • Conduct steady-state and dynamic simulations using Aspen HYSYS software for process optimization.
  • Explore advanced process control techniques to manage operating conditions and improve efficiency.

Course content

3 sections • 24 lectures • 3h 25m total length

  • Crude Oil - Distillation Feed6:34

    Explore crude oil as the feed for atmospheric and vacuum distillation, mapping hydrocarbons from methane to asphalt, and distinguish paraffins, iso-paraffins, naphthenes, and aromatics.

  • Distillation Objective4:49

    The distillation objective is to fractionate the complex crude oil into simple cuts, from light ends (C1–C4) to naphtha, gasoline, distillate, and residue. Atmospheric and vacuum distillation enable this separation.

  • Atmospheric Distillation Pressure4:58

    Raise the pressure above one atmosphere to increase boiling points and enable condenser-based separation of light ends. A reflux drum condenses mostly C3 and C4, aiding feed movement.

Description

This comprehensive course on refinery distillation (theory, Simulation and Control) provides an in-depth exploration of the distillation process essential for crude oil separation. Participants will learn about distillation feeds, product specifications, and the critical operating conditions that influence efficiency and yield.

The course covers the fundamentals of process flow diagrams (PFDs), allowing students to visualize and understand the intricate relationships between unit operations. Emphasis will be placed on various unit equipment, including distillation columns and heat exchangers, highlighting their design and operational parameters.

Using Aspen HYSYS software, students will engage in steady-state simulations to analyze and optimize distillation processes. The course will also delve into dynamic modeling, providing insights into transient behaviors and control strategies necessary for maintaining optimal operation by adding different PID controllers to control process flow, temperature and pressure also to make sure we are maintaining defined specification of the atmospheric distillation products.

Additionally, participants will explore advanced process control techniques, ensuring they can effectively manage variations in feed composition and operating conditions. By the end of the course, students will be equipped with practical skills and theoretical knowledge to design, simulate, and optimize distillation systems in a refinery setting, preparing them for real-world challenges in the petrochemical industry.

Who this course is for:

  • Chemical Engineering Students: Seeking to deepen their knowledge of refinery processes.
  • Industry Professionals: Engineers and operators looking to enhance their skills in distillation and process simulation.
  • Researchers: Individuals interested in advancing their understanding of distillation technologies.
