摘要：

This paper describes in detail the numerical solution of a dynamic process developed for post-combustion absorption based CO2 capture. The method used in this work is sequential modular integration. This means that each process unit is modeled and integrated individually while co-ordination algorithms are developed to synchronize process units in time and provide input between connecting units. A pressure-flow interaction algorithm (p-f network solver) is also developed to provide estimates of downstream pressures for each unit. This is required in order to calculate the outlet flow from the units. The complete process plant model is developed to enable simulation of the post-combustion CO2 capture process at power plant load variations. Two examples of load variations are presented in this paper. (C) 2013 The Authors. Published by Elsevier Ltd. Open access under CC BY-NC-ND license.
