Process for eliminating sulfur dioxide from a gas by means of an absorption mass that can be regenerated by reaction with hydrogen sulfide

摘要

the invention relates to a process for the removal of sulphur oxides and sulphur dioxide.contained in gases such as industrial flue gas characterized in that the gas is brought into contact with an absorber (4) with an absorbent solid containing magnesium oxide and at least a noble metal of group viii in conditions of sulfur oxides are the main (in the form of magnesium sulfate.then the absorbent is regenerated by contact with a solid is used as a reducing gas containing hydrogen sulfide in a regenerator (8).
