Abstract: The dynamic behavior of three process configurations proposed for CO2 capture from flue gas is investigated. In the previous paper () the different configurations were investigated with respect to energy requirement and capital costs and the best configurations were defined based on CO2 avoided cost and total capture cost. In addition to the economy, the dynamic behavior is important when operation of the plant is considered. In this study the transient behavior of the vapor recompression and the split-stream configurations are investigated when different disturbances happen, and the results are compared with the conventional configuration as a benchmark. All process configurations are operationally feasible with the proposed control configuration. The results show that the conventional configuration is the most inherently resilient to disturbances, and that the vapor recompression configuration can handle disturbances better than split-stream configuration. The same relative reduction in reboiler duty has more negative effect (more reduction in capture ratio) for split-stream configuration than two other configurations. The control structure generated is able to control the plant for all configurations except the situation where the reboiler duty is an active constraint. In this situation the energy loss will increase and it is better to find another control variable to pair with reboiler duty. This will be done in future studies. [Copyright &y& Elsevier]
