ABSTRACT:
The invention relates to a process for removing sulfur oxides, particularly sulfur dioxide, contained in gases such as industrial fumes, characterized in that the gas is contacted with a solid absorbent containing magnesium oxide, in such conditions that sulfur oxides are fixed mainly as magnesium sulfate and then the used solid absorbent is contacted with a gas stream containing elemental sulfur in such conditions that magnesium oxide is regenerated with the production of an effluent of sulfur dioxide-containing gas.
