Study on Mathematical Models for Optimization of SCR Catalyst Replacement Cycle and Strategy

In this paper, the efficient management of SCR catalyst in coal-fired power plants is studied and the models for catalyst activity forecasting, reactor performance computing and catalyst replacement efficiency estimating are established. These models can be used to study catalyst replacement strategies and evaluate their benefit and efficiency. The performance of SCR reactors is determined by the hierarchy calculation method which summarizes the potential from the fot layer of the catalyst to its last layer. The activeness of the catalyst in running and the new catalyst samples tested, and the activeness loss function is obtained, which lays the foundation for catalyst upgrading and benefit evaluation in the practice.
