An intensive professional development training course on

Gas Treatment

The Chemistry and Technology of Gas Processing

Why Choose this Training Course?

This interesting 5-day training course concentrates on treatment processes in the entire natural gas value chain, from discovery, exploration and transportation through to sales and marketing.

Natural or associated gas as well as refinery off gases may contain a number of acidic contaminants, primarily H2S and CO2, inert gases, helium and nitrogen and in rare cases natural gas may contain Radon. Removal of these acidic components can be divided into two broad categories, chemical and physical. Sometimes a mixture of chemical and physical solvents are used either in a continuous or batch process. The H2S can be converted to Sulphur using a modified Claus Sulphur Recovery unit. In this course each of the various Sulphur recovery processes are examined and their chemistry is explored in detail. Other techniques that will be covered include Shell’s greener alternative Thiopaq.

This training course will feature:

  • Origins and chemical characteristics of Natural Gas
  • Gas Treatment Technologies and Processes
  • Amine Systems and Physical Solvents Design Criteria
  • Troubleshooting Gas Sweetening and Sulphur recovery Units
  • All the current Sulphur Recovery Technologies


What are the Goals?

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

  • Understand the Technology, Chemistry and Thermodynamics of Gas Treatment
  • Appreciate the Many Aspects of Gas Treating and Sulphur Recovery Processes
  • Identify the Main Process Steps and Discuss the Key Features of Gas Treating
  • Demonstrate an Understanding of Many Facets of Amine Sweetening Technologies
  • Evaluate, Monitor, and Troubleshoot Gas Treating Operations


Who is this Training Course for?

This training course is suitable to a wide range of professionals within the Oil and Gas Industries but will greatly benefit:

  • Engineers and Process Technologists
  • Product and Inspection engineers
  • Maintenance or project engineers.
  • Operations and Laboratory Chemists
  • Consultants and Sales professionals


How will this Training Course be Presented?

Gas Treatment and Sulphur Recovery is a highly interactive, applied and stimulating learning experience, with presenter led opportunities to advance ones opinions and ideas through discussions, workshops, class exercises, case studies and examples.

To ensure a thorough understanding of the concepts introduced during the programme a mix of learning methods will be used, including lecture style presentations, open discussion and group work.
