This comprehensive course explores the principles and applications of natural gas liquefaction systems. A special focus is given to the Closed Expansion Liquefaction Process. Students will gain in-depth knowledge of thermodynamic principles, process equipment, and system optimization in LNG production. The course covers various liquefaction technologies, including cascade systems, mixed refrigerant processes, and expansion-based systems, with practical applications in industrial settings. For this intermediate-level course, the learner must have a basic knowledge of LNG and its uses.

Learning Objectives

The learning objectives of THIS SESSION Eight are to understand at an intermediate level the following: Upon completion of this course, students will be able to:
