CO2 capture in integrated steelworks by commercial-ready technologies and SEWGS process

- CO2 capture by SEWGS, MEA and MDEA assessed by process simulations.
- SEWGS achieves the highest efficiencies (about 37.7%).
- SEWGS achieves direct CO2 emission reduction from the power block of almost 90%.
- Significant energy penalties are predicted for MEA cases with high capture rates.
- MDEA system can approach 90% direct CO2 avoided with 34.6% electric efficiency.
