This public summary report focuses on the DISPLACE campaigns performed in Lulea Sweden and Petten, Netherlands demonstrating the use of a H2 rich fuel for reheating purposes and DISPLACE process for decarbonization.
C4U aims to advance two emerging carbon capture technologies, known as DISPLACE and CASOH, which have the potential to tackle up to 94% of the CO2 sources in a steel mill. Both DISPLACE and CASOH technologies involve high temperatures gas-solid separation processes that reduce the exergy penalty associated with CO2 capture. During the CASOH process, the steelworks arising gasses are transformed into heat suitable for in-plant heat demands and a H2-rich product, which is integrated with steel-works internal processes or used for the external production of added value products. Additionally, flue gasses originating from oxy-fuel firing to provide process heat to reheating ovens are decarbonized using DISPLACE technology. The DISPLACE technology is a high temperature sorption-displacement process for CO2 recovery from off-gases or combustion product flue gases at a steelwork.
