CO<sub>2</sub> Abatement in the Steel Industry through Carbon Recycle and Electrification by Means of Advanced Polymer Membranes

The potential of advanced polymer or hybrid polymer membranes to reduce CO<sub>2</sub> emissions in steel production was evaluated. For this, a conceptual process design and assessment was performed for a process that is a combination of carbon recycling and electrification of the steel...
