Diagnosis System for Continuous Cooking Process

چکیده
Industrial systems generate a lot of information for operators. Increased measurement information flow might cause difficulties for the process operators to observe the process states and faulty process operation. In this study, measurements and statistical variables are combined by fuzzy logic to generate key factors for several points in the continuous cooking digester. The overall diagnosis system combines the key factors into one system which is used for the operational purposes and as a helping tool for process condition monitoring. Copyright c ° IFAC2005

Clustering Algorithms in Process Monitoring and Control Application to Continuous Digesters
In this study, the controlability of the Kappa number in two cooking applications is investigated. The Kappa number is one of the quality measures in the pulp cooking process and usually the only on-line measurement. It is a measure of the residual lignin content in the pulp. The cooking of the pulp mainly takes place in the digester, where the significant part of the lignin is removed from the...
متن کاملEnhancing kappa number control in downflow lo-solidstm digester using diagnosis and modelling
In this study, Kappa number prediction and diagnosis in continuous Downflow Lo-Solids cooking application is investigated. Gustafson’s Kappa number model is applied for the prediction of the blowline Kappa number. New cooking temperature set point is solved iteratively based on the difference between the predicted and target blow-line kappa numbers. The main active variables for the Kappa numbe...
متن کاملEfficient Synthesis of Biodiesel From Waste Cooking Oil Catalysed by Al2O3 Impregnated with NaOH
Due to the high price of virgin vegetable oils and the drawbacks of the homogeneous catalytic transesterification, in this work an economically profitable alternative process was proposed for biodiesel synthesis in which transesterification of the low-cost waste cooking oil (WCO) with methanol in a heterogeneous system was done. Alumina impregnated with sodium hydroxide was utilized as a solid ...
