Atmospheric residue desulfurization (ARDS) process is extensively used in upgrading of heavy petroleum oils and residues to more valuable clean environmentally friendly transportation fuels and to partially convert the residues to produce low-sulfur fuel oil and hydrotreated feedstocks. Graded catalyst systems in multiple reactors are used in the process in order to achieve hydrodesulfurization (HDS), hydrodemetallization (HDM), hydrodenitrogenation (HDN), and conversion of residues to distillates at desired levels.
This course is designed to provide in depth practical review of the core elements of (ARDS) process technology including the key variables that affect product yields, properties, catalyst issues, reaction mechanisms, process design, operation, control and optimization . A framework is presented for troubleshooting operating problems and, throughout this discussion, participants are encouraged to describe their specific challenges.
The course includes practical worked examples and case studies to reinforce the key learning.

Objective

 

Upon completion of this course, participants will have gained a solid understanding of the key elements associated with the design, operation, monitoring and troubleshooting of ARDS units. This will include the impact of feed quality, catalyst, operating conditions and unit design on product qualities. In addition they will have gained some valuable insight into how to optimize, debottleneck and troubleshoot their ARDS units efficiently.

TRAINING OUTCOME

  • Overview of the Catalytic Processes in a Refinery, with a special emphasis on ARDS units.
  • ARDS Catalyst Evaluation Techniques.
  • An understanding of Reactor and Catalyst interaction.
  • The operation, control and troubleshooting of a reactor and associated heaters, heat exchangers and distillation equipment.
  • An overview of reactors, practical solutions as well as theory.
  • An understanding of essential reaction concepts.
  • Valuable practical insights for trouble free design and field proven techniques for commissioning, start up and shutdown of reactor, heater, heat exchanger and distillation operations of the ARDS units.
  • To tailor your approach to specific design, analysis and troubleshooting problems.
Audience

This is a comprehensive core skills course for professionals dealing with all aspects of the Hydrotreating units. The course will be highly valuable to all engineers involved in the operation and design of Hydrotreating facilities. Additionally, the course will be useful to any technical personnel wishing to gain a perspective of how desulfurization fits into the operation of a complete refining plant. Those who are experienced in other fields and seek a review of the fundamentals of desulfurization technology will also find this course most beneficial.
