Gas Sweetening

The use of natural gas has become a prime source of energy generation.  Contaminants within the gas stream cause problems with freezing, corrosion, erosion, plugging.  Environmental, health and safety hazards must also be removed.  Sour natural gas compositions can vary over a wide concentration of H2S, CO2 and hydrocarbon components.

This course focuses on the removal of H2S and CO2 from sour gas which is called “sweetening.”   The end user of natural gas must be assured that the gas meets sales gas specifications and that the supply of gas must be available at all times at the contracted rate. Participants will gain an understanding of gas treating facilities, how they must be designed to convert a particular raw gas mixture into a sales gas that meets the sales-gas specifications, and how such facilities must operate without interruption. 

This course will provide participants with the fundamental knowledge of gas sweetening process and its operation as applied in today’s oil and gas industry.

Day 1

Gas Purification Processes

  • Types of gas purification processes
  • Flow diagrams and P&ID’s
  • Process equipment and its purpose
  • Safety and environmental concerns

Participants will gain knowledge of the types of gas sweetening processes and the associated equipment used to safely and efficiently sweeten sour gas.  System layout including process flows and normal operating parameters as well as energy optimization will also be discussed. Day one concludes with a review of operation, maintenance and safety procedures for gas sweetening systems as well as discussions stressing safety and environmental compliance and concerns.

Day 2

Gas Treatment Absorbers

  • Alkanolamines
  • Operational issues of amine sweetening
  • Bulk CO2 removal by membrane unit

Day two will have focus on understanding of the configuration, scope and operation of amine gas sweetening systems.  Safe, efficient system operation with respect to manipulating control variables such as flow, temperature, pressure, and concentrations of process materials will be reviewed while addressing operational issues that may affect overall performance and safety. Membrane technology will also be discussed while paying particular attention to its advantages, portability and safety in the gas sweetening process.
