Liquefied Natural Gas (LNG) - an Introductory Course

In Liquefied Natural Gas (LNG) - an Introductory Course, you'll learn ...

• Natural gas's origins and the required pre-treatment before natural gas is converted to LNG
• The reasons for and methods of reducing the concentration of acid gases, mercury, water vapor, and heavy hydrocarbons before liquefaction
• LNG special phenomena, such as Rapid Phase Transformation, LNG spill behavior, LNG storage tank inventory rollover, the effects of nitrogen in the LNG, and re-condenser use
• The importance of proper design (spring hangers, expansion joints, etc.) and maintenance

Overview

This course is the first in a series of Liquefied Natural Gas (LNG) courses. The course is designed for engineers entering the specialty of LNG or who want to understand the basics of LNG production, storage, transportation, safety measures, and vaporization.

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 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 are converting from dirtier fossil fuels to natural gas or vaporized LNG.

Learners taking this course are expected to have a basic understanding of thermodynamics and heat transfer (boiling, condensation pressure, temperature relationships, etc.).

The learner will understand natural gas's origins and the required pre-treatment before natural gas is converted to LNG. The reasons for and methods of reducing the concentration of acid gases, mercury, water vapor, and heavy hydrocarbons before liquefaction will be covered.

Many unique characteristics of LNG will be covered in this course.

Also, emphasis will be given to the need for relief valves and attention to LNG special phenomena, such as Rapid Phase Transformation, LNG spill behavior, LNG storage tank inventory rollover, the effects of nitrogen in the LNG, and re-condenser use. The importance of proper design (spring hangers, expansion joints, etc.) and maintenance will be presented.

Importantly, the learner will appreciate the need to maintain safe and reliable plant operations through proper training of plant personnel. The need to strictly follow procedures, recognize anomalies, understand the technologies and the use of the Management of Change process will be covered.

The need for auxiliary and backup auxiliary systems will also be presented.

The course will aim to develop a culture of preemptive thinking, continuous learning, continuous improvement, and ethical behavior to avoid accidents and avoid unreasonable risks.

The most important intention of this course is to give the learner the basic technical knowledge, at an introductory level, that he/she needs to start their study on how to continue to make the Liquid Natural Gas Industry “Safe and Reliable.”

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

• Why natural gas is liquefied and stored, and vaporized
• The pretreatments needed to clean up natural gas before it can be liquefied
• The hazards associated with natural gas
• The methods of storing LNG
• The methods of transporting LNG
