TRAINING DESCRIPTION

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

The H?S, together with some or all of any carbon dioxide (CO2) present, is removed from the natural gas or refinery gas by means of one of the gas treating processes described in the previous section.

The resulting H?S -containing acid gas stream is flared, incinerated, or fed to a sulphur recovery unit.

This course for as an effective practical shortcut to understand the gas sweetening and sulphur recovery process and all features and troubleshooting problems encountered in the plant operations. With increasing demands to natural gas over the world, sour gases are being tapped for utilization after purification. But, the natural gas that is transported to the market must meet legal and safety requirements; it must be non-toxic, non-corrosive and safe to environment. For that reasons, gas conditioning or specifically gas treating is a very important step in gas processing scheme. H?S, and CO?, are removed to certain level through a gas sweetening process.

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

This short course is designed to give the attendants the fundamentals of natural gas conditioning and processing including some of the details of the process.

Upon the successful completion of this course, participants will be able to:-

  • To present the fundamentals of all aspectsof Sulphur recovery from process selectionthough operation and plant optimization.
  • Identify properties, specifications and end uses of natural gas.
  • Discuss about typical natural gas processing operations, including:
    • Dehydration
    • Acid gas removal
    • Recovery of ethane, propane and NGL (natural gas liquids)
    • Sulphur recovery 
  • Discuss about the production of liquefied natural gas (LNG).
  • Recognize the different equipment and facilities found in natural gas processing plants.
  • Discuss about the fundamentals of gas transportation and distribution.
  • Describe how each component in the unit operates, the effects of process variables
  • Describe how to monitor the unit and make necessary adjustments
  • Explain how to perform routine maintenance, and troubleshooting common problems affecting proper operation of the unit, in order to achieve the goals of gas sweetening and Sulphur Recovery units.
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.
