Introduction

Sulfur Recovery Units (SRUs) are essential in refining and gas processing plants, where they facilitate the removal of hydrogen sulfide (H₂S) from acid gas streams and convert it into elemental sulfur. This process is vital for safeguarding downstream equipment, preventing corrosion, and meeting stringent environmental emission standards. As sulfur recovery processes grow more complex—due to factors such as varying feed conditions, increased throughput, and evolving emission regulations—engineers and technical professionals must have in-depth knowledge of SRU systems, including the Claus process, tail gas treatment, and optimization methods. This Design and Optimization of Sulfur Recovery Units (SRUs) training course offers a comprehensive understanding of SRU design, operation, control, and troubleshooting, with hands-on insights into system performance, sulfur plant integration, and emissions management.

What are the Goals?

By the end of this training course, participants will be able to:

  • Understand the Claus process and sulfur recovery fundamentals
  • Design and evaluate key components of a sulfur recovery unit
  • Operate and monitor SRUs to maintain efficiency and compliance
  • Analyze tail gas treatment systems and emission reduction methods
  • Troubleshoot common operational issues in sulfur recovery systems

Who is this Training Course for?

This training course is suitable to a wide range of professionals but will greatly benefit:

  • Process and Operations Engineers
  • Refinery and Gas Plant Engineers
  • Environmental Compliance and HSE Professionals
  • Plant Supervisors and Control Room Operators
  • Chemical Engineers involved in sulfur plant design or operations
  • Maintenance and Reliability Engineers

How will this Training Course be Presented?

This training course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented. This includes an interactive mixture of lecture-led learning & group discussions.
