Abstract
This doctoral thesis presents the development of soft sensor empirical models using support vector machine (SVM), and dynamic polynomial models for the continual estimation of the mole fractions of 2,2-dimethylbutane, 2,3-dimethylbutane, 2-methylpentane and 3-methylpentane as important product quality indicators in a refinery isomerisation process. During the model development, critical steps were taken, including selection and preprocessing of the industrial process data, which are broadly discussed in this thesis. Evaluation of the developed models on independent data sets and their implementation in the system for the advanced process control showed their reliability in estimating of the component contents. The soft sensors will serve primarily as a replacement during the process analysers’ failure and service periods, as well as it will be a part of advanced control of isomerisation process.
Abstract (croatian)
Ovaj doktorski rad predstavlja razvoj empirijskih modela softverskih senzora korištenjem metode potpornih vektora i dinamičkih polinomnih modela. Senzori su namijenjeni kontinuiranoj procjeni molnog udjela 2,2-dimetilbutana, 2,3-dimetilbutana, 2-metilpentana i 3-metilpentana kao ključnih komponenti u proizvodu rafinerijskog procesa izomerizacije. Tijekom razvoja modela, poduzeti su ključni koraci kao što su izbor i predobrada procesnih podataka, što je naširoko objašnjeno u ovom radu. Vrednovanje razvijenih modela na nezavisnim skupovima podataka i njihova implementacija u sustav za napredno vođenje procesa pokazalo je njihovu pouzdanost u procjeni udjela navedenih komponenti u proizvodu procesa. Softverski senzori prvenstveno će služiti kao zamjena tijekom kvara procesnih analizatora te u servisnim periodima, kao što će biti i dio naprednog vođenja procesa izomerizacije.
