Abstract
Improved systems and methods are disclosed for producing sulfur dioxide using oxygen and submerged combustion. By incorporating a vapour phase combusting step in addition to the submerged combusting step, the downstream sulfur condenser may be made substantially smaller with reduced complexity and cost. Further, energy recovery is simplified and improved.
