Giuffrida, A. Cobden, P.D. van Dijk, H.A.J. Ruggeri, F. Consonni, F. Publication year 2020 Abstract Mitigation of CO2 emissions in the industrial sector is one of the main climate challenges for the coming decades. This work, carried out within the STEPWISE H2020 project, performs a preliminary techno-economic assessment of the Sorption Enhanced Water Gas Shift (SEWGS) technology when integrated into the iron and steel plant to mitigate CO2 emissions. The SEWGS separates the CO2 from the iron and steel off-gases with residual energy content (i.e. Blast Furnace Gas, Basic Oxygen Furnace Gas and Coke Oven Gas) and the produced H2 is sent to the power generation section to produce the electricity required by the steel plant, while the CO2 is compressed and transported for storage. Detailed mass and energy balances are performed together with a SEWGS cost estimation to assess the energy penalty and additional costs related to CO2 capture. Results demonstrates the potential of SEWGS to capture over 80 % of CO2 in the off-gases, which results in entire plant CO2 emission reduction of 40 % with a Specific Energy Consumptions for CO2 Avoided (SPECCA) around 1.9 MJ/kgCO2. SEWGS outperforms a commercial amine scrubbing technology which has a SPECCA of 2.5 MJ/kgCO2 and only 20 % of CO2 avoided. The cost of CO2 avoided calculated on the basis of a fully integrated steel plant is around 33 €/tCO2 compared to 38 €/tCO2 of the amine technology. © 2019 The Authors Subject Energy EfficiencyEnergy / Geological Survey NetherlandsSorption enhanced water gas shiftCO2 captureIron and steel industrySPECCACost of CO2 avoidedTechno-economic assessment To reference this document use: http://resolver.tudelft.nl/uuid:188f7ae8-a2af-4840-ac93-ffe56a379ac4 DOI https://doi.org/10.1016/j.ijggc.2019.102935 TNO identifier 871927 Publisher Elsevier Ltd ISSN 1750-5836 Source International Journal of Greenhouse Gas Control, 94, 1-13 Article number 102935 Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
