Application of the Soft-sensing Technique in Pulp Washing Process
摘要
Abstract
The most important quality indices of evaluating pulp washing performnce are residual alkli in the washed pulp and the Baume degree of the extracted black liquor.Considering the fact of direct on-line instrument measuing of them is very difficult,an adaptive softsensing instrument for measuring residual soda and Baume degree is proposed.Voluminous plant operation data collected by DCS and simulated results from a theoretical moedl are pooled together and used to build the adaptive soft-sensing instrument based on the BP neural network and least square mcthod.Application of the soft-sensing technique in pulp washing control system shows that the control system can run smoothly over a long period on site.关键词
