Title:
METHOD AND SYSTEM FOR REFORMING BYPRODUCT GAS IN STEELMAKING PLANT
Document Type and Number:
Japanese Patent JP2007009069
Kind Code:
A
Abstract:
To increase the quantity of industrially useful carbon monoxide through reducing carbon dioxide emissions in steelmaking plants and also reforming carbon dioxide in the byproduct gas in the steelmaking plants.
In a steelmaking furnace 1, carbon dioxide-rich byproduct gas 54 is generated in the process of manufacturing crude steel 56 from iron feedstocks 51 including iron ore and scrap and then fed via a gas holder 7 and a compressor 2 to a gas reforming furnace 4 where carbon-containing solid compounds 52 such as coal and wastes are gasified. The carbon dioxide in the thus fed byproduct gas is reduced into carbon monoxide by char generated in the gas reforming furnace 4. Thereby, the calorific value of the byproduct gas is increased.
