Gas Processing Fundamentals

Overview:

Introduction:

Gas processing involves the separation, purification, and treatment of raw natural gas to remove impurities and extract valuable components, ensuring the production of marketable gas and by-products like natural gas liquids (NGLs). This training program covers the principles and practices of treating natural gas for various applications. It emphasizes the theoretical understanding required for effective gas processing in the oil and gas industry.

Program Objectives:

At the end of this program, participants will be able to:

• Explore gas treatment processes and system analysis in subsurface operations.

• Gain knowledge of gas dehydration, absorption, refrigeration, and LNG production.

• Explore the scope of LNG (NGL) gas processing in oil and gas facilities.

• Gain insights into the transfer operations and measurement techniques in the gas field.

• Acquire expertise in gas compression, processing, NGL recovery, and troubleshooting.

Targeted Audience:

• Process engineers along with petroleum and production engineers.

• Field operators and technicians.

• Company staff involved in gas treatment and processing.

• Process engineers who are new to the profession.

• Managers and government officials involved with supervising gas processing operations.

• Managers involved in the planning and development of new gas processing facilities or modifying existing facilities.
