dc.description.abstractIn this study a first assessment of the utilization of the Calcium Looping (CaL) as a CO2 capture method in the steel production process has been done. The applicability of CaL for CO2 capture from the blast furnace gas of the Top Gas Recycling Blast Furnace (TGR-BF) proposed by ULCOS has been studied. Data of previous experimental campaigns where CaL was tested for post-combustion capture in a 200 kWth pilot plant has been used to simulate in Aspen PlusTM the CaL working under the TGR-BF conditions. The results of the CaL simulation have been used to compare CaL with VPSA, proposed by ULCOS as CO2 capture method, and amines adsorption (MDEA), presented by the IEAGHG. The three technologies have been energetically compared and its integration in a reference steel mill has been studied, offering CaL the advantage that is able to meet the electricity demand of the steel mill, avoiding the requirement of an additional power plant. As a direct consequence, the CO2 emissions in the CaL steel mill can be strongly reduced in comparison with the other capture technologies. A determination of the costs of the CaL plant has been carried out and an economic comparison of the cost of steel production and the cost of CO2 avoidance for the different capture technologies has been done. The results showed that for the proposed steel mill and under the assumptions done, CaL offers the lowest CO2 avoidance cost.
