Integrated assessment of carbon capture and storage technologies in coal-based power generation using CAPE tools

CAPE methods as well as process integration have been used in this paper to estimate and compare key performance indicators of coal-based power generation with and without carbon capture and storage (CCS). This evaluation explores the most used coal-based power generation technologies as follow: pulverized coal (PC) plants in both situations sub- and super-critical conditions and integrated gasification combined cycle (IGCC) plants. Post-combustion capture using chemical solvents was considered for PC and pre-combustion capture using either chemical or physical solvents were considered for IGCC. The case studies generate around 400 - 500 MW net power for IGCC and 900 - 1000 MW net electricity for PC with 90 % carbon capture rate.
