However, blast furnace top gas typically contains 35 to 60% by volume of N 2> 20 to 30% by volume of CO, 20 to 30% by volume of CO 2 and 2 to 15% by volume of H 2 .
  • About 30 to 40% of the blast-furnace top gas produced in the production of pig iron is generally used for heating the hot blast for the blast furnace process in blast furnaces; the remaining blast furnace gas can be used in other areas of the plant for heating purposes or to generate electricity.
  • pig iron is converted to crude steel. Inflating oxygen to molten pig iron removes interfering contaminants such as carbon, silicon, sulfur and phosphorus. Since the oxidation processes cause a strong evolution of heat, scrap is often added in amounts of up to 25% based on the pig iron as a coolant. Further, lime for slag formation and alloying agent are added. From the steel converter, a converter gas is withdrawn, which has a high content of CO and also contains nitrogen, hydrogen and CO 2 .

It has also been proposed to heat the blast furnace with plasma. The process of the plasma-heated blast furnace requires neither hot air nor oxygen and no additional replacement reducing agent. However, the introduction of new blast furnace processes is a serious encroachment on the proven technology of pig iron and crude steel production and involves considerable risks. against this background, the object of the invention is to improve the CO 2 balance of a metallurgical plant which has a conventionally operated blast furnace for producing pig iron and a conventionally operated converter steelwork.
