Gas Processing Fundamentals

Introduction:

Gas processing involves the separation, purification, and treatment of raw natural gas to remove impurities and extract valuable components. It ensures the production of marketable gas and by-products such as natural gas liquids (NGLs). This training program covers the principles of gas processing, including gas treatment methods and key engineering considerations. It aligns with industry standards for natural gas conditioning, separation, and purification.
