Abstract

Process for the manufacture of liquid sulfur dioxide; by the combustión of sulfur with air, the cooling at low temperature gives the combustión gases containing the sulfur dioxide, by the liquefaction of the sulfur dioxide under pressure at a temperature between 30 and 70º c. Below zero, and by the separation of the liquid sulfur dioxide from the remaining gas; characterized in that the sulfur dioxide, which has remained in the remaining gas, is transformed by contact oxidation into sulfur trioxide, that the sulfur trioxide is absorbed, forming concentrated sulfuric acid, and that the concentrated sulfuric acid is subjected to the splitting, at least in part, within the sulfur combustión zone, forming sulfur dioxide.
