Etymology: "Desulfurising" is the British spelling of the present participle and gerund of "desulfurise", meaning to remove sulfur compounds from something, most often fuel or metal. The verb is built from "de-", a prefix meaning "remove or reverse", attached to "sulfur", the element whose name came into English through Latin "sulphur" and an earlier Old French form. Put together, the word literally means "un-sulfuring" or taking sulfur away. The practical reason the process matters is that sulfur compounds in crude oil and coal burn to sulfur dioxide, a major source of acid rain and air pollution, which is why refineries and power plants run desulfurising steps. The same logic applies to molten metals, where dissolved sulfur makes steel brittle.
