Abstract: Drops and bubbles are of great importance to the extractive metallurgists in his attempts to speed up processes by the use of sprays, foams, and jets. The metallurgist is doing this by using discontinuous phases so as to increase the surface area across which reactions take place, and to make convective processes in the vicinity of these surfaces as vigorous as possible. It is well known that the presence of sulphur in steels unfavourably affects its mechanical and physical properties. Further, it has been observed that the sulphur present in pig iron directly goes to the steels in more or less same amount. So, for quality steel production it is necessary to reduce the sulphur content in the pig iron which is used as raw material in the various steel-making processes. Extensive work has been done in past in removal of sulphur during extraction and refining but at the cost of productivity and economy. However, external desulphurisation has off-late proved to be quite useful process for removal of sulphur in between iron making and steelmaking stages. Still, substantial work may be done to optimize the external deSulphurisation process with regard to the technology and desulphurising agents used to improve the economy of the process
