CO2 Capture and Utilization in Cement and Iron and Steel Industries

AbstractThis paper evaluates different technological options for the reduction of CO2 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 CO2 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 CO2 to urea and methanol industries, which are two prospective users of CO2 captured in Europe
