NGL Extraction is a key processing unit for any gas conditioning or processing facility. Whether for hydrocarbon dewpoint control (minimal NGL recovery), or for deep NGL extraction (C2+ recovery that can be achieved in turbo-expander plants), the NGL Extraction unit is the heart of the gas processing plant.

This short course details the processing technology options for hydrocarbon dewpoint control and deep NGL extraction, and discusses the considerations that are important to the most optimal process selection for a given field development. The course content will meet the needs of a facilities engineer that is supporting a hydrocarbon dewpoint facility, moderate NGL extraction plants, as well as those assigned to Gas Sub-cooled Process (GSP) or turbo-expander facilities. The key pieces of equipment will be covered, as well as the overall combined processing unit.

The self-paced online modules cover the following topics:
  • NGL Extraction
  • Compact heat exchangers and fired heaters
  • Operation of Expansion Refrigeration Devices
  • Common Process Configurations for NGL Extraction
  • Types of Internals in Mass Transfer Columns

The virtual, instructor-led session will review the methods required to analyze the heat and material balance for NGL extraction plants from first principles. The two problem assignments will compare and contrast the differences between two different technologies used for hydrocarbon dewpoint control (mechanical refrigeration and turboexpander plants). These learnings also apply directly to GSP plants.

The problem debrief and round table discussion session will cover the practical learnings gained from the problem assignments. The difference between lean and rich gas processing will be discussed. A deep discussion on the limitations on brazed aluminum heat exchangers and their operating considerations will be held to raise the awareness of the issues associated with this type of heat exchanger. During the round table discussion, common operating problems of refrigeration and turboexpander facilities and their potential solutions will be discussed where the participants will have the opportunity to share their experiences and ask specific questions regarding their specific facilities.

Prerequisites, which participants can test out of, include Basic Conversion, Gas and Liquid Physical Properties, Multicomponent Phase Behavior, Effect of C6+ Characterizationon Phase Behavior, Fundamental Applications of Phase Envelopes, Thermodynamic Principles and the First Law of Thermodynamics, Second Law of Thermodynamics and Energy Balance Equations, and Using PH Diagrams to Perform Energy Balance Calculations
Production and processing personnel involved with natural gas and associated liquids, to acquaint or reacquaint themselves with gas conditioning and processing unit operations.

This course is for facilities engineers, process engineers, senior operations personnel, field supervisors, and engineers who select, design, install, evaluate, or operate gas processing plants and related facilities.

These short courses are ideal for mid-career professionals that have experience in the industry and have been transferred to a new role or assignment.

They are also ideal for new engineers that need to get up to speed quickly on the primary principles of gas processing with a deep dive on the issues of the short course topics.
