Natural Gas Processing: Dehydration, Refrigeration and Fractionation Optimization


Course Description

  • This intensive course is designed to familiarize technical professionals with the design and operation of several common gas plant processing blocks. The course will explain dehydration systems used in typical field gathering and plant facilities, including a review of options available. The course will explain on mechanical propane refrigeration systems typically used in Hydrocarbon Dew point and NGL Recovery systems, including a review of design and performance enhancements. The course will also discuss on tower operations and troubleshooting used in absorption and fractionation services, with optimization and key performance indicators discussed for each tower in each application. The course is aimed at engineers, technologists and operators involved in the operation and optimization of gas processing facilities.

Course Objectives

  • By the end of the training, participants will be able to:
  • Identify chemical composition of natural gas.
  • Identify basic terminology (Atom, Chemical Compounds and Molecules, Physical Compounds,
