Full-plant Analysis of a PSA CO2 Capture Unit Integrated In Coal-fired Power Plants: Post-and Pre-combustion Scenarios

摘要: Abstract It is well proven that a general policy to address the worldwide issue of global warming cannot disregard Carbon dioxide Capture and Storage (CCS) in portfolio tools. Pressure Swing Adsorption (PSA) processes are believed be promising option for achieving more energy cost-effective capture CO 2 from large point sources, especially coal-fired power plants. Nevertheless, there gap knowledge with respect information approaches integration using PSA The main contribution this work fill gap, providing plant-level comparison other techniques decarbonization (i.e., state-of-the-art absorption processes) terms separation performance, efficiency footprint technology. Full-plant analyzes were developed based on dynamic computational model representing plants operating cycle, both post- pre-combustion configuration. resulting plant performance compared absorption-based systems same reference assumptions. post-combustion scenario outputs reveal benchmark process outperforms alternative. Even though requirements met, relatively penalty very seem highlight current unsuitability capture. Conversely, analysis shows as separation, technology, results just slightly lower than implementing method. However, novelty non-maturity technology application leaves window open future improvements.
