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?
