Top gas recycling blast furnace for low CO_2 ironmaking - final results of ULCOS trials

摘要

IT is widely recognised that CO_2 in the atmosphere is the main component influencing global warming through the greenhouse effect. The steel industry is known as an energy intensive industry and as a significant emitter of CO_2. In the traditional processes for producing steel, emission of CO_2 is inevitable, especially for the blast furnace process, which is the main source of CO_2 in an integrated steel works. In this process carbon is needed for the reduction of the iron ore. Breakthrough iron-making technologies are required for further significant reduction of carbon consumption and so CO_2 emissions.
