ABSTRACT:
An improved continuous cyclic process for removing oxides of sulfur from a waste gas with a regenerable particulate adsorbent in which hot adsorbent particles pick up SOx in a first fluid transport riser, followed by separation of clean gas from sulfur-contained particles which are then recycled to a desorber in which they are contacted at elevated temperature with a mixture of reducing gas and water vapor for release of sulfur as hydrogen sulfide. The adsorbent particles are then recycled in the process. Means are provided for removing particulates in the waste gas.
