Course Description

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