Etymology: "Desulphurises" is the third-person singular present form of "desulphurise", so the verb's history is what matters here. It is built from "de-", a prefix meaning removal or reversal, attached to "sulphur" and the verbal ending "-ise". The base, "sulphur", is the older word: it came into English from Old French "soufre", ultimately from Latin "sulphur", and it has long been a name for the yellow element with the characteristic smell of burning matches. The "-ise" ending, from Greek-derived Latin "-izare" through French, turns a noun into a verb meaning to treat or act upon in a certain way, which is why "sulphur" becomes "sulphurise", to combine or treat with sulphur. Adding "de-" reverses that action, so "desulphurise" means to strip sulphur out. The word's shape is a plain technical formation, and the prefix and suffix do exactly the work their parts suggest.
