Sulphur Recovery

This one-day course will provide participants with a thorough review of the design, operation and optimization of the modified Claus sulphur recovery process, including a review of process chemistry, process equipment, operating problems, catalyst deactivation, tail gas technologies, and new technologies related to the sulphur recovery industry, such as degassing and pelletizing.  The presentation is designed for personnel involved in the design or operation of sour natural gas processing plants and sulphur recovery facilities.

Participants will learn to:
•	Describe the different pieces of equipment in a modified Claus sulphur recovery train.
•	Select the mode of operation between straight through or split flow.
•	Identify the factors affecting the recovery efficiency of sulphur.
•	Discuss the different methods of reheating the process gas stream between catalytic stages.
•	Understand the processes of deactivation of the catalyst.
•	Review the different methods of process enhancements.
•	Describe the different tail gas clean-up methods.
•	Determine the density of liquid sulphur 
•	Calculate the recovery efficiency of sulphur of the sulphur plant.

A complete set of course materials and lunches are included.

Edward Wichert has an extensive background in the oil and gas industry. This includes experience at the technical level as well as in management in drilling, oil and gas production and processing, reservoir engineering and economic analysis. He gained this experience through employment in the oil and gas industry in Alberta, with small, intermediate and large companies. He holds a B. Sc. degree in Petroleum Engineering and a Master's degree in Chemical Engineering. His research interests are mainly related to sour gas. He has published several articles dealing with determining the properties of sour gas and the application of technology in sour gas production and processing, as well as the disposal of acid gas by compression and injection. He is an independent oil and gas industry consultant in Calgary, and was Adjunct Professor in the Department of Chemical and Petroleum Engineering at the University of Calgary from 1996 to 2005. He has presented courses in natural gas technology worldwide, and is the recipient of the Award of Merit from the Canadian Gas Processors Association, in 1994, and the Lifetime Achievement in Hydrocarbon Measurement award from the Canadian Institute of Hydrocarbon Measurement, in 2003.
