Credit: 7 CPD

Length: 121 pages

This course is the first in a 4-course series.

• Part 1 is based on understanding thermodynamic concepts and using pressure enthalpy charts.
• Part 2 builds onto part 1 but uses thermodynamic software instead of pressure enthalpy charts for analysis and goes into additional depth.
• Part 3 (consisting of Parts 3A and 3B) builds on parts 1 and 2 to apply thermodynamics to understand air conditioning and refrigeration systems from ¼ hp size units to 300,000 hp size units. Part 3A focuses on pure substances and mixed refrigerant liquefaction systems. Part 3B focuses on nitrogen expansion liquefaction systems.

Note that each course in the series is a “stand alone” course. It is not necessary to first complete Parts 1 and 2 in order to study Parts 3A & 3B, provided the learner already possesses the prerequisite knowledge needed.

This course (Part 1) introduces the learner to natural gas’s origins and the production of Liquefied Natural Gas (LNG). LNG is widely used around the world. It is a very compact form of natural gas in liquid form. It is used on very cold days to supplement gas coming from the interstate pipelines to supply gas load centers like New York, Boston, and other major load areas. Natural gas (essentially the same as vaporized LNG) is the cleanest burning fossil fuel as it contains the least amount of carbon of all the fossil fuels. Thus, many electric power plants now use natural gas or convert from dirtier fossil fuels to natural gas or vaporized LNG.

As part of this Part 1, learning an open expansion natural gas liquefaction system will be analyzed in a step-by-step manner to understand how it produces liquefied natural gas. The computations will be by use of pressure enthalpy charts for methane.

The focus of this learning will be on the application of thermodynamics to understand liquefaction processes. A major part of this learning will be the analysis of an open expansion natural gas liquefaction plant process which applies all the learnings of this course.
