About the course
This is the LNG-industry version of our popular G-4 course, with expanded coverage of refrigeration and LNG technologies. The course includes in-depth information on basic LNG gas conditioning and processing. In addition, instructors will explain the LNG supply chain that consists of four main links - natural gas exploration and production, liquefaction, shipping, receiving, and distribution. The course covers relevant details of both the mixed refrigerant (APCI) and cascade (ConocoPhillips) processes in LNG liquefaction. New liquefaction processes are addressed, such as mixed fluid cascade and dual nitrogen refrigeration cycles. Versions of this course have been taught in many of the world's base-load and peak-shaving LNG plants, such as Australia, Indonesia, Malaysia, Norway, Qatar, UK, and West Indies.
