D634 Acid Gas Compression and Injection

Course Facts

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


This one-day virtual course provides a comprehensive overview of the design and operational aspects of acid gas compression and injection projects.  The presentation includes a detailed discussion of the phase behavior of acid gas and outlines the methods for estimating the properties of acid gas for the design of the compression and injection facilities.  It also addresses the methods for controlling corrosion and prevention of the formation of hydrates.  Design considerations of compression and cooling equipment, injection line, well completion, and reservoir selection are also discussed.  Technical and operations persons involved in the design or operation of acid gas injection projects would greatly benefit from this course. 

A comprehensive set of course notes is included.
