Sulphur | The Canadian Encyclopedia
Processing. In Canada, elemental sulphur is recovered from the processing of sour natural gas with a high hydrogen sulphide (H 2 S) content, and from the refining of high sulphur-bearing crude and heavy oil. Hydrogen sulphide is a highly toxic and corrosive component and is the main source of sulphur in Canada; most producing sour-gas fields contain 1% …
