Simulations and process analysis of the carbonation-calcination reaction process with intermediate hydration

► The CCR Process for CO2 and SO2 removal is modeled and analyzed. ► Internal process parameters and its effect on the CCR Process are examined. ► Net plant efficiency decreases 20-22% when placed in a subcritical power plant. ► The CCR Process uses less O2 than oxycombustion and less steam than amine scrubbing. ► The CCR Process can increase, maintain, or decrease net electrical output.
