Abstract (en)
Sulphur present in petroleum oils represents a very undesirable pollutant when the oils are burnt. A process of treating oil containing sulphur is provided wherein the oil is contacted with hydrogen fluoride. The hydrogen fluoride converts the sulphur to a sulphur fluoride which may be removed from the oil. The sulphur fluoride may then be converted to other forms of sulphur thus allowing for regeneration of the hydrogen fluoride for reuse in the process.
