What is Desulphurization? Definition from Corrosionpedia

Mar 31, 2017 Desulfurization refers to the industrial process of removing sulfur from a mineral resource mixture such as crude oil. It predominantly involves a gas-purification industrial procedure used to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from a given mineral resource.. Desulphurization may also be known as gas sweetening or amine gas treating.

Process for reducing the iron content of CaO-rich slags

We claim: 1. A process for reducing the iron content of a CaO-rich slag formed during the desulphurization of a crude iron melt, which comprises adding finely-ground fluorspar to the melt, in a ladle in which the crude iron is transported to a steel making unit, or adding it to the ladle prior to adding the crude iron thereto, in an amount such that the slag remains solid.
