An intensive professional development training course on

Amine Gas Sweetening
and Sulphur Recovery

Chemistry and Troubleshooting of
Acid Gas Removal Processes

Why Choose this Training Course?

Natural Gas is considered to contribute less greenhouse gas emissions than other fossil fuels. It has therefore been touted to be the fuel of choice by nations and is considered to serve as a transition until renewable sources mature to the point that they can replace fossil fuels. The abundance of this fossil fuel and the diversity of its composition, requires that in many cases it has to be treated to meet a variety of specifications.

This Amine Gas Sweetening and Sulphur Recovery Training Course aims to equip the attending delegates with the knowledge of all the current processes used for the removal of acidic and other contaminants (primarily H2S and CO2 but also water vapor, mercury Nitrogen, Argon) from hydrocarbon streams.

This Amine Gas Sweetening and Sulphur Recovery Training Course will concentrate on Sulphur Recovery Processes including a thorough understanding of the chemical limitations of the Claus Unit and the modifications that have followed, including the Super Claus and Euroclaus. The course will conclude with an examination of the various tail gas treatment processes including Shell’s SCOT and Thiopaq.

This AZTech training course will feature:

  • Understanding of Amine Gas Processing Units’ operating and maintenance techniques
  • Familiarization of Sulphur Recovery process operating and design considerations
  • Understand common operational problems and their troubleshooting
  • Ability to put in place measures to maximize efficient operation
  • Improve process optimization techniques
  • Interface with other gas processing units

What are the Goals?

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

  • Gain a thorough Understanding of Amine Sweetening and Sulphur Recovery Technologies
  • Grasp an Explanation of the Key Features of Gas Treating
  • Understand the Limitations Imposed by Gas Processing Thermodynamics
  • Distinguish the Main Criteria in Process Design
  • Evaluate, Monitor, and Troubleshoot Gas Treating and Sulphur Recovery Operations

Who is this Training Course for?

The course is specifically designed to be of substantial benefit to personnel within the Oil and Gas Industries such as:

  • Technologists
  • Mechanical engineers
  • Inspection engineers
  • Maintenance or project engineers
  • Operations personnel

It is designed for both technical and non-technical personnel as well as operational staff at professional level employed in refineries, petrochemical, and oil and gas process industries.

It will serve as an introduction to acid gas removal and sulphur recovery technology for those who are unfamiliar with the subject and will also assist those who need the ability to progress to a detailed knowledge of the gas processing technologies.

How will this Training Course be Presented?

This AZTech training course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented. Amine Gas Sweetening and Sulphur Recovery is a hands-on, stimulating learning experience. The programme will be highly interactive, with opportunities to advance your opinions and ideas. Participation is encouraged in a supportive environment.

To ensure the concepts introduced during the programme are understood, they will be reinforced through a mix of learning methods, including lecture style presentation, open discussion, case studies and group work.
