Toward Sustainable Solvent-Based Postcombustion CO2 Capture: From Molecules to Conceptual Flowsheet Design

摘要: Abstract Solvent-based postcombustion carbon dioxide (CO2) capture requires minimum retrofitting of current CO2-emitting power plants but is challenging because the high energy penalty in solvent regeneration and environmental impacts degradation. Research efforts are predominantly based on lab pilot-scale experiments to select solvents process systems which improve overall performance this technology. Notwithstanding value experimental efforts, study proposes an efficient computational approach for screening a vast number commercial novel configurations. Computer-aided molecular design, advanced group contribution methods, synthesis, multicriteria sustainability assessment combined provide new insights solvent-based CO2 capture. This provides details data requirements, highlights several high-performance configurations, quantifies benefits from economic, life cycle, hazard perspective. Thus, it also information approaches, focusing narrower, near-optimum design space.
