Gas Processing and Conditioning

An In-Person Training Course by Esanda.


    In-House sessions are available upon request.

    Course Overview:

    This introductory course is designed to provide participants with a complete and up-to-date overview of gas conditioning operations and processing technology. It covers product specifications and the processes available to condition the gas in order to meet these requirements. Participants will understand the nature and purpose of key gas processing operations, and how the individual operations are integrated into plants to process diverse feed streams received from oil and gas fields around the world.


    Learning Objectives:

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

    • Learn the basics of gas reservoir volume and field life calculation
    • Understand how GC&P works and its problem solving
    • Become familiar with pipelines and compressors
    • Develop a good background on natural gas processing and ability to explain the contract specification terms
    • Identify the various gas process separators, their sizing and become familiar with slug catchers and other separator types
    • Recognize the role & importance of water content & hydrocarbon dew point as applied in gas conditioning & processing technology
    • Understand the prediction, formation and inhibition of hydrates and be able to review the process of liquid, desiccant, and membrane type dehydration
    • Analyze the process of hydrocarbon recovery (NGL) and gain knowledge on mechanical refrigeration
    • Emphasize the thermodynamics of gas and be able to employ the removal of acid gases such as H2S, CO2, CS2, COS & RSH
    • Review & improve the processing of sour gas and discuss the Claus catalyst sulphur recovery process


    The Course Is Designed For:

    • Those directly involved in supervising gas processing operations
    • Managers involved in the planning and development of new gas processing facilities or modifying existing facilities
    • Production Supervisors, Senior Operators and those involved with gas production and injection
    • Individuals involved in negotiation contracts for the sale of Natural Gas, LPG and NGL Products
    • Newly employed engineers and technicians in the oil and gas processing industry
    • Both technical and non-technical personnel
    • Those employed in the activities that support gas processing
