The objectives of this diploma thesis are to learn about thermodynamical processes in a chemical industry, based on the knowledge learned, to create and to identify a model of a thermodynamical process in a real chemical tank. To create a model the chemical tank itself is described with regards to its shape, sensor placement and physical properties. Model will be identified using real data. Data for identification will be analysed to avoid problems during identification. Methods used will be both linear and nonlinear according to own choice, validated on a real data samples. Results of all approaches taken to identify the model will be compared to decide which method prvided the best results. Current control approach is described and possible improvements are suggested.
