“…CO 2 capture opportunities may economically feasible in steel production considering the probable future costs for CO 2 , for example in the EU Emission Trading Scheme (EU ETS) [77]. Besides, steel production is a large production process with relatively high CO 2 concentrations, utilization of pure oxygen and recoverable heat [78]. Fig.…”

The ironmaking process is the most significant source of CO 2 emission in the iron and steel industry, which generates large quantities of greenhouse gases. Recently, oxygen blast and top gas recycling have been applied to the blast furnace to improve the energy efficiency and reduce the pollution from the ironmaking process. However, as a new ironmaking technology, the oxygen blast furnace with top gas recycling (TGR-OBF) is still under development. This paper focuses on the investigation of the energy consumption and carbon emission for the TGR-OBF process by modeling the stack, the bosh, the combustion zone, and the gas recycling system. Effects of the key parameters in the TGR-OBF process on the carbon consumption of reactions and the energy consumption of the system are investigated by orthogonal experiments. Our results indicate that the TGR-OBF process has the advantages of reducing energy consumption and CO 2 emission. The low temperature and high reducing environment in the new furnace is favorable to lower the coke gasification and increase the reaction rate of iron oxide. The recycling of the top gas can significantly reduce CO 2 emission, and the main advantage comes when the stripped CO 2 is stored.

“…Different possibilities have been envisaged for carbon capture retrofit, since different CO 2 emission points exist. As reported in [7], 70% of the emissions come from flue gas produced in the blast furnace (BF) hot stoves and in the power plant, while coke oven gas (COG) and basic oxygen furnace gas (BOFG) are responsible for 9% and 7%, respectively [8]. This work models (i) a reference iron and steel plant based on Ref.…”

This paper evaluates different technological options for the reduction of CO 2 emissions in heavy industries through their capture and use of best available technologies. This work presents the approach and the preliminary results obtained in the evaluation of iron and steel industry using oxygen blast furnace gas recycling after CO 2 capture in a pressure swing adsorber. It also evaluates the use of post-combustion capture using amines for retrofitting in the cement industry. Both are considered the most feasible technologies to be deployed in Europe in the medium term. Calibration, validation and future work regarding iron and steel industry model are described. The study finally assess the potential of cement and iron and steel industries to supply CO 2 to urea and methanol industries, which are two prospective users of CO 2 captured in Europe.
