Dynamic modelling and simulation of a post-combustion CO2 capture process for coal-fired power plants
文献摘要：
Solvent-based post-combustion capture tech-nologies have great potential for CO2 mitigation in traditional coal-fired power plants.Modelling and simula-tion provide a low-cost opportunity to evaluate perfor-mances and guide flexible operation.Composed by a series of partial differential equations,first-principle post-com-bustion capture models are computationally expensive,which limits their use in real time process simulation and control.In this study,we propose a first-principle approach to develop the basic structure of a reduced-order model and then the dominant factor is used to fit properties and simplify the chemical and physical process,based on which a universal and hybrid post-combustion capture model is established.Model output at steady state and trend at dynamic state are validated using experimental data obtained from the literature.Then,impacts of liquid-to-gas ratio,reboiler power,desorber pressure,tower height and their combination on the absorption and desorption effects are analyzed.Results indicate that tower height should be designed in conjunction with the flue gas flow,and the gas-liquid ratio can be optimized to reduce the reboiler power under a certain capture target.
