Abstract
Methods and configurations are drawn to a plant in which an effluent gas () comprising oxygen and sulfur dioxide is catalytically reacted with hydrogen sulfiden () and hydrogen and/or carbon monoxide () to form a treated gas that is substantially oxygen free and in which sulfur dioxide is converted to hydrogen sulfide. In most preferred aspects, the hydrogen sulfide is provided to the process via a recycle loop (B).
