A B S T R A C T PROCESS FOR REMOVING SULPHUR FROM THE WASTE GAS OF A REDUCTION SHAFT FURNACE A novel process for removing the sulphur contained in a gaseous compound by absorbtion from at least part of the waste gas of a reduction shaft furnace (1) for iron ore is described. The waste gas is initially cleaned in a scrubber (13) and cooled, followed by desulphurlzation, during which the sulphur-absorbIng material is constituted by part of the sponge iron produced in the reduction shaft furnace. Desulphurization advantageously takes place at a temperature in the range 30 to 60°C. It is preferably carried out on the CO2 separated from the blast furnace gas and the blast furnace gas part used as export gas.
