Abstract
AbstractWithin Carbon2Chem® the presented subproject focused on oxymethylene ethers (OME) as possible diesel fuel components. Six different scenarios for CO2emission reduction in steel mills were calculated, in four of which methanol is generated as an OME intermediate from steel mill gases. Potential synergies in raw material and energy streams of the coupled processes were identified. Shared process streams and equipment could lead to savings in capital and operational expenditure. CO2reduction volumes and avoidance costs were calculated for the six scenarios. If coupled with methanol production, natural gas‐based direct reduced iron processes offer the chance for quantitative CO2emission reduction at the lowest CO2avoidance costs. Energy required for this process could be co‐fed, e.g., as renewable electricity.
