Introduction

The rapidly increasing worldwide demand for natural gas as an energy source requires expertise in gas engineering technology, which involves several production operations such as dehydration, acid gas removal, recovery of natural gas liquids, and the production of liquefied natural gas. In addition, one involved in such an industry needs to be familiar with different gas sources, specifications, storage requirements, transportation, and distribution.

This course will start by defining what natural gas is, its properties, specifications, and end-use. Then, typical gas processing operations will be discussed, including dehydration, acid gas removal, recovery of ethane, propane, and NGL (natural gas liquids), and liquefied natural gas (LNG) operations. Sulfur recovery will also be discussed. Typical equipment and facilities that are found in typical natural gas processing operations will also be discussed including compressors, vessels, relief systems, and safety systems.

This short course is designed to give the attendants the fundamentals of natural gas handling systems and facilities including some of the details of the process. Specifically, by attending this course you will:

Gain a deep knowledge of the properties, specifications, and end uses of natural gas.
Gain a deeper understanding of typical natural gas processing operations, including:
- Dehydration
- Acid gas removal
- Recovery of ethane, propane, and NGL (natural gas liquids)
- Sulfur recovery

Gain a deeper understanding of the production of liquefied natural gas (LNG).
Gain a deeper knowledge of the different equipment and facilities found in natural gas processing plants.
