Gas Sweetening & Sulfur Recovery

Course Duration/Credits

Five days/3.0 CEUs/30 PDHs


The removal of acidic components (primarily H2S and CO2) from hydrocarbon streams can be broadly categorized as those depending on chemical reaction, or adsorption. Processes employing each of these techniques are described. The principle process stream is the removal of the acid gases by counter flowing contact with an amine solution, commonly known as Amine Gas Sweetening.

This 5 days course will provide participants with technical information and proactive training that will aid in the industries sulfur emission problems. Participants will acquire knowledge in all aspects of sulfur recovery such as process design, troubleshooting, operations, plant optimization and a review of tailgas units and will optimize the plant efficiency. They will be able to work hands-on along with testing methods, prevention, troubleshooting, and optimization. In addition, this course emphasizes on process selection, practical operating issues, technical fundamentals, and integration of the sweetening facilities into the overall scheme of plant and provides a comprehensive technical review of gas treatment, including operating and troubleshooting issues. Related topics such as liquid product treating, corrosion, materials selection and troubleshooting will also be reviewed.

The acidic components removed are termed acid gas streams (containing H2S,) and may be converted to elemental sulphur in a Sulphur Recovery Unit. Various Sulphur Recovery processes (primarily The Modified Claus Process) are discussed. This course will cover every aspect of sulphur recovery process, and provide a comprehensive background to anyone involved in the industry.
