This course teaches how to correctly monitor natural gas for impurities using a variety of equipment; and
introduces the many components of natural gas and how, if unprocessed, they affect the quality,
increase corrosion potential, and can lead to the formation of lethal substances such as hydrogen sulfide.
Course Prerequisites
- GTA Web-Based Training
o Gas Quality Instrumentation - GTA Instructor-Led Training
o Gas Sampling
