The question as to whether crude oil contains elemental or free sulfur has never been definitely settled, although there are many references in the literature to the presence of elemental sulfur in distillates and as condensed crystals in distillation equipment. There are also many references which indicate that a sulfur-bearing crude oil is very likely to evolve hydrogen sulfide during distillation. Inasmuch as distillation is one of the basic tools in separating the components of petroleum, it is helpful in knowing the sulfur content.
