ABSTRACT:
Gases containing elemental sulfur are purified therefrom by contact with sulfur trioxide in oleum; additionally the gas may be purified by carbonaceous material. In one embodiment, shown in the drawing, the process is used to remove elemental sulfur from sulfur dioxide produced by reaction of molten sulfur (3) with sulfur trioxide. A portion of the sulfur trioxide is by-passed (6) and introduced into the overhead line (5) of the sulfur dioxide reactor (4). The gases are purified in a second reactor (11) containing a pool of oleum (10).
