To evaluate the technical, economic, and environmental feasibility of integrating amine-based postcombustion CO2 capture systems into both new and existing coal-fired power plants.
Developed performance and cost models for monoethanolamine (MEA)-based CO2 absorption systems.
Integrated the capture models into an existing power plant simulation framework that accounts for multipollutant emissions control.
CO2 avoidance costs were higher for plant retrofits than for new installations, primarily due to greater energy penalties from less efficient heat integration and site-specific constraints.
Capture costs were slightly offset across all evaluated scenarios by revenue from SO2 emission trading credits generated by the amine scrubbing process.
