| titleOfInvention |
Desulphurisation of gases in the production of pig iron |
| abstract |
The invention relates to a process for the production of molten pig iron (1) in which iron oxide-containing starting materials (2) are reduced in a first reduction plant (4) by means of a reducing gas (5) to a partially reduced first iron product (3) and in a melter gasifier (11). are melted to the molten pig iron (1), wherein the spent reducing gas (5) as export gas (6) in a second reduction plant (7) is introduced, and wherein a sulfur-containing gas (13), together with an oxygen-containing gas (9) and / or is introduced together with dust (16) into the melter gasifier (11) and / or into the reducing gas line (12).n n n Furthermore, the invention relates to a device for carrying out the method.n n n Thus, sulfur-containing gas 13 in the production of liquid pig iron 1, or DRI, while increasing productivity can be used without polluting the environment or negatively affecting the quality of the molten pig iron 1 or DRI. |
