Performance evaluation of high-sulphur coal-fired USC plant integrated with SNOX and CO2 capture sections

Integration with the CO2 removal section leads to a noteworthy USC plant efficiency reduction of about 10.5 percentage points. The CO2 specific emissions, which for the reference plant were about 760 g/kWh, are marginally influenced by the SNOX system, but are greatly reduced by the introduction of the CO2 removal system, decreasing to about 100 g/kWh.
