ABSTRACT:
A method for the production of gaseous sulphur from sulphur dioxide by means of a thermally balanced mixture which comprises a mixture of sulphur dioxide with air or oxygen and a gaseous or liquid hydrocarbon, the proportions of the components of such a mixture being so adjusted as to conform to the conditions that the gaseous reaction products from such a mixture shall have a minimum temperature determined by the liquidus temperature of the melt into which such reaction products are to be injected or the liquidus temperature of the products of reaction between the components of the melt and the injected gaseous reaction products, whichever is the greater, and that the partial pressure of oxygen in such gaseous reaction products is in accord with the desired composition of the melt.
