Refiners are facing a dynamic business environment. Crude prices are volatile. Heavy, highsulfur and acidic opportunity crudes are increasingly available. Demand for lighter products is increasing; product legislation and emissions standards are tightening; and health, safety and environment mandates also have to be met. This necessitates that refiners are now required to reduce the products sulfur content before it can be sold and satisfy market demand of lighter products. This is most commonly done by hydroprocessing. Hydrotreating and hydrocracking processes share many common features, so they often are discussed together as “hydroprocessing” . Hydrotreating removes contaminants from distilled crude oil fractions and intermediate process streams. Hydrocracking converts heavy oil fractions into lighter, more valuable products.

For refiners to sustain their profit margins, economical access to state-of-the-art technology is a must. Hence, this course is designed to provide in depth practical review of all hydrotreating and hydrocracking processes key variables that affect product yields, properties, catalyst issues, reaction mechanisms, process design, operation, control, troubleshooting and optimization . Several significant product quality specifications (for instance, 10–15 ppm sulfur in diesel and gasoline), nitrogen and aromatic content, cetane number, API gravity, smoke point, cold flow properties such as pour point, cloud point and cold filter plug point and many other topics will be deeply discussed in this course.

A framework is presented for troubleshooting operating problems and, throughout this discussion, participants are encouraged to describe their specific challenges.

This course will feature: 

  • Lectures/discussions on hydrotreating and hydrocracking process technologies, roles and techniques for improving process operations, designs and applying optimization techniques. 
  • Open discussion on the latest development on the applications of hydroprocessing.
  • Actual troubleshooting case studies.
  • Group activities (workshop) on process design, operation, maintenance, inspection, control and optimization



Upon completion of this course, participants will be able to

  • Gain in-depth knowledge of the exact role of hydrotreating and hydrocracking unit regarding to feeds and product's characteristics, analyze the importance and impact of operating parameters on process output, identify common potential incidents in the reaction section: origin, consequences, solutions and preventive measures. 
  • Evaluate different flow schemes for Hydrotreating and Hydrocracking processes.
  • Understand process design and operation variables for better H2-conversion performances. 
  • Grasp the experiences of chemistry/kinetics, function of catalysts, clean production, environmental issues of very typical upgraded fuel productions.
  • Develop deep understanding of mass/H2/energy balance in refining processes.
  • Identify unit-specific damage mechanisms.
  • List the key steps in the inspection planning process. 
  • Identify unit-specific problems and describe typical solutions

This course is intended for anyone who takes part in the Hydroprocessing facilities in oil refining and petrochemical industries or who helps decide Hydroprocessing investments.
