Why Choose Us

The SRU Design and Operation Training Course gives process, operations, and engineering professionals a comprehensive, technically rigorous understanding of Sulfur Recovery Unit design, process chemistry, operational management, tail gas treatment, troubleshooting, and optimisation — grounded in the Claus process and the real-world challenges of gas processing and refining environments.

Sulfur Recovery Units are critical process assets in natural gas processing, refining, and petrochemical operations. Their performance directly determines sulfur recovery efficiency, SO₂ emissions compliance, environmental regulatory status, and overall plant profitability. Operating and managing SRUs effectively requires a depth of technical knowledge that spans reaction chemistry, process design, control systems, and safety management.

This course addresses that knowledge directly — covering the full SRU lifecycle from acid gas feed preparation and thermal reactor design through catalytic stages, tail gas treatment, SCOT process, emissions control, and operational troubleshooting, to recovery optimisation, energy management, and H₂S safety. Every module is grounded in the specific technical realities of sulfur plant operations.

The SRU Design and Operation Training is built for professionals who are accountable for SRU performance and want the technical depth to design, operate, troubleshoot, and optimise these critical units with confidence and precision.

Course Goals

What are the Goals?

The SRU Design and Operation Training Course is designed to develop comprehensive technical capability across SRU design, process chemistry, operational management, tail gas treatment, emissions control, troubleshooting, and performance optimisation — all within the context of gas processing and refining operations.

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

  • Explain the role of SRUs in gas processing and refining and identify the sulfur compounds present in natural gas and refinery gas streams
  • Describe the fundamentals of the Claus process — including thermal and catalytic stages, stoichiometry, and reaction chemistry
  • Evaluate acid gas composition, prepare feed for SRU processing, and explain thermal reactor design and reaction furnace operation
  • Identify and explain the function of waste heat boilers, sulfur condensers, reheaters, and catalytic reactors in the SRU process
  • Apply knowledge of tail gas treatment units including the SCOT process, hydrogenation reactors, and amine absorbers
  • Evaluate SO₂ emission control strategies and assess compliance with environmental regulations and recovery efficiency requirements
  • Manage safety considerations in H₂S-rich environments and apply lessons learned from operational improvement and incident case studies
