N632 Sour Gas Treating

Course Facts

Course Code:
1 days
0.8 Continuing Education Units
8 Professional Development Hours
Certificate Issued Upon Completion


This one-day course is designed for engineers, technologists, plant supervisors, and plant operators wanting to broaden their understanding of sour gas treating.  The session includes a review of the evolution of sour gas sweetening solvents, and the problems associated with the operation of sour gas treating, such as corrosion and foaming.  Design and operational considerations for the process train equipment are presented.  Scavenger methods of treating sour gas are also discussed.  A comprehensive set of notes is provided.
