Wobbe Index
The Wobbe Index is a key measurement tool used in the natural gas industry to check if gas can be safely and efficiently used in equipment like stoves or industrial burners. Think of it like a quality score for natural gas - just like food products have nutritional values, natural gas has this score to ensure it will work properly in different machines. It helps workers ensure that when gas sources are switched (like changing from one supplier to another), all equipment will continue to operate safely. This measurement is especially important for roles involved in gas processing, distribution, and quality control.
