Abstract:The purpose of the optimal control of pulp washing is not only to ensure the quality of pulp washing, but also to reduce the energy consumption. Water is one of the most important resources; reduce water consumption is to reduce energy consumption. This paper analyzed the material balance in pulp washing and evaporation. The model related dilution factor and washing water was established, the model was optimized by penalty function, which can turn the constrained problem into unconstrained. It showd that the method can find the optimal dilution factor, reduce the consumption, bring greater economic benefits to the enterprises.
