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 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 uses. 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. Sulphur recovery, tail gas conditioning and process control 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. Finally, the fundamentals of gas transportation and distribution will be discussed.

Objective

After Completion of this course the attendee will understand the following:

The purposes and steps of natural gas conditioning and processing.
Amine sweetening unit description and troubleshooting.
Water content in natural gas.
Hydrates; nature, formation conditions, prediction, and inhibition.
Glycol dehydration unit; description, troubleshooting and design basis.
Molecular sieves dehydration unit; description, troubleshooting, and design basis.
External refrigeration unit description.
Gas expansion through J.T. valve and turbo-expander.
Gas Fractionation different schemes.

Audience

Technical and non-technical personnel involved in the activities of natural gas industry. Specifically, technical, operations and maintenance personnel who had limited exposure to this area, or professionals involved in other areas of the gas industry that require a comprehensive overview of natural gas processing will find this course ideally suited for them.
