METHODS AND SYSTEMS FOR PRODUCING DIRECT REDUCED IRON AND STEEL MILL FUEL GAS |
摘要 |
A process for producing reducing gas for use in the production of direct reduced iron (DRI) and fuel gas for use in a steel mill, comprising: compressing a coke oven gas (COG) stream in a compressor; passing the compressed coke oven gas stream through an activated charcoal bed to remove tars from the compressed coke oven gas stream; separating a hydrogen-rich gas stream from the · compressed cleaned coke oven gas stream using a pressure swing absorption unit; providing the hydrogen-rich gas stream to a direct reduction shaft furnace as reducing gas; and providing a remaining gas stream from the pressure swing absorption unit to a steel mill as fuel gas. Both once through and recycle options are presented. Optionally, basic oxygen fumace gas (BOFG) is added to the reducing gas. |
