Blast-furnace process with CO2-lean blast furnace gas recycle and production plant for same

摘要

Process for producing metal from ore in a blast furnace and blast-furnace plant for use in said process, whereby oxygen is heated in an oxygen preheating installation upstream of the blast furnace and hot oxygen thus obtained is introduced into the blast furnace and whereby CO2 is extracted from the blast furnace gas to generate CO2-lean blast furnace gas and CO2-lean blast furnace gas thus obtained is likewise introduced into the blast furnace.
