Process for separating sulfur dioxide from a gaseous stream, having a temperature of about 65.5 to 426.6ºC and containing sulfur dioxide mixed with sulfur trioxide, comprising: Contacting the gas stream with an aqueous metal sulphite absorbent solution to absorb sulfur dioxide from the gas stream and produce a spent absorbent tributary containing the corresponding metal bisulfite; treat the spent absorbent effluent to produce sulfur dioxide and regenerate sulphite, and recycle the regenerated sulfite to said contacting step, characterized in that the gas stream, before coming into contact with said absorbent solution, is first treated to remove trioxide from sulfur of it.
