Gas Conditioning and Processing - Special - G-5

Petroskills Registerbutton

The course has been designed to cover sweet gas processing and NGL recovery topics in a 5-day format using a commercial simulator to perform calculations. A basic working knowledge of the commercial process simulation package being used will provide the best opportunity to achieve the learning objectives of this course. Volumes 1 and 2 of the John M. Campbell text books, Gas Conditioning and Processing, are used as the basis for the material presented in this course. A comprehensive course exercise based on a typical gas processing facility which can be applied to either onshore or offshore facilities is used for this course. The problem is developed in stages, as the material is covered, using a commercial simulator package (typically Promax? or UNISIM?). At the completion of the course the participant will have developed a process simulation model that includes a dew point control process, a mechanical refrigeration process with economizers, hydrate inhibition using MEG, and NGL liquid product stabilization with recycle.

Engineers needing an intensive training in natural gas processing and associated liquids recovery processes with emphasis on the use and benefits of a simulation package. Those having a good understanding of basic sweet gas processing operations or who have attended the G-4 Gas Conditioning and Processing course will benefit most from this course.

You will Learn:
