Prediction and Control of Blow-line Kappa Number
نویسندگان
چکیده
Two industrial continuous cooking processes producing both softwood and hardwood pulp were studied. Real time kappa number profiles of conventional and Downflow Lo-Solids cooking were modelled. Gustafson’s kappa number model with optimised parameters was used. Blow-line kappa numbers were successfully predicted before cooking zone. New kappa number control strategy is presented. In control strategy, temperature set point is determined iteratively using prediction model of kappa number. Copyright c © IFAC2005

Enhancing 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 کاملMolecular Docking of Curcumin With Breast Cancer Cell Line Proteins
Background: Breast cancer is known as the most widely recognized dangerous tumors; therefore, the most common reason for mortality among all instances of harmful neoplastic illness in females. This is because the lack of specific signs and symptoms at the early stage and at the aggressive nature. Currently, breast cancer treatment such as chemotherapy, surgery and radiotherapy has not been effe...
متن کاملExperimental and Neural Network Prediction of Elongation and Spread after First Stage of Fullering
Fullering process is a type of open die forging. In this research, elongation and maximum sideways spread in final shape of a billet after the first blow of a fullering process are predicted by designing a back propagation multilayer perceptron neural network. Several experiments are conducted using lead as the model material. Billets with three different square cross-sections are used in these...
متن کاملEvaluating the Validity of Quasi-Static Analysis for Prediction of Vessel Mooring Line Forces
Quasi-Static analysis of moored vessels is vastly used for engineering designs, as a substitute to the numerical simulation of dynamic mooring analysis. Yet, the level of validity of the results of quasi-static analysis is a matter of discussion. In the present study, the validation of the assumptions behind the quasi-static analysis of mooring vessels is examined with application of a dynamic ...
متن کاملInvestigation and Evaluation of Rolling Resistance Prediction Models for Pneumatic Tires of Agricultural Vehicles
Wheel numeric and different versions of mobility numbers are important models for predicting the rolling resistance. In this study, data related to the rolling resistance of cross ply and radial ply tires were compared with the resultant values from several models. Also, the preciseness of models in rolling resistance prediction was evaluated. For this purpose F test and 1-1 line method (p≥ 0.0...
