TBN (True Boiling Point)
TBN, or True Boiling Point, is a standard way to analyze and describe oil products in the petrochemical industry. It helps determine the quality and characteristics of oil-based materials by showing at what temperatures different parts of the oil will boil. Think of it like a detailed recipe that tells refineries how to process crude oil into useful products like gasoline or diesel. When you see TBN mentioned in job descriptions, it usually relates to quality control, laboratory analysis, or refinery operations roles.
