Format and Duration
3 days

Summary

This course is designed to familiarize technical professionals with the design and operation of several common gas plant processing blocks. Day one will be spent on dehydration systems used in typical field gathering and plant facilities, including a review of options available. Day two will focus on mechanical propane refrigeration systems typically used in Hydrocarbon Dew Point and NGL Recovery systems, including a review of design and performance enhancements. Day three will focus on tower operations and troubleshooting used in absorption and fractionation services, with optimization and key performance indicators discussed for each tower in each application.

Feedback

The course was perfect, not too complicated and not too simple. Truly the best 24 hours in a classroom setting that I spent. If you have any exposure to Dehydration, Refrigeration, and Fractionation in your facilities, this course will break it down for you perfectly and you'll walk away knowing you learned something extremely applicable. I would highly recommend this course! Dale Kraus is an excellent instructor, very knowledgeable and extremely experienced.

Duration and Training Method

This is a three-day classroom course with lectures, examples and exercises. Participants will earn 2.4 CEUs (Continuing Education Credits) or 24 PDHs (Professional Development Hours).
