To remove sulfur or sulfur compounds from a substance, typically coal, oil, or industrial gases.
From de- (removal) + sulfur. Modern industrial term coined in the 20th century as environmental regulations made sulfur removal necessary in fuel processing.
Desulfuring became a crucial environmental technology because burning high-sulfur coal creates acid rain—removing that sulfur before or after burning prevents mountains and lakes from getting poisoned.
