Abstract
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 desulphurization, 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.degree. to 60.degree. C. It is preferably carried out on the CO.sub.2 separated from the blast furnace gas and the blast furnace gas part used as export gas.
