Rectification and reactive distillation columns are the main of all units in the petrochemical and refining industry. Soft sensors consist of mathematical models that estimate of the quality of an output product in real time are used for technologica

The problem of adaptive soft sensor development with the use of clustering methods is considered in the examples of a reactive distillation process for the production of methyl tert-butyl ether and of crude distillation unit. We suggest to use cluste

We consider a clustering-based construction of a soft sensor with adaptive model structure and parameters and with the time factor taken into account by the example of an industrial reactive process. We propose to improve an earlier-developed adaptiv

The problem of predictive modeling under condition of the nonlinearity of the mass−transfer plant (MTP) based on the experimental data is considered. To analyze the structural identifiability of the process under study and identify factors that aff

The paper discusses the development of a soft sensor (SS) for an MTBE plant in the cases when the training sample either is small or does not comprise the whole of quality range because of process plant non-stationarity as well as the difficulty and

The problem of estimating the model parameters for predicting a quality indicator for an output product of a reactive distillation process is considered. The feedback loop in the prediction error of the output variable is used in the mathematical mod

Approach to the solution of a problem of structural and parametrical identification of models of the soft sensors (SS) of technological plants on the basis of robust regression and information criteria is proposed. The robust regression is used for m
