Abstract:
The paper proposes a systematic approach to the elaboration of a structured
mathematical model and modeling of chemical and technological systems under
uncertainty exemplified by a sulfur production unit. The novelty of the suggested
method lies in the choice of a suitable model type for each element of the system based
on the systematic analysis, development of the selected model type and their merger
into a unified system of models. The method was successfully implemented to construct
a system of models for major units of the catalytic reforming plant at the Atyrau Oil
Refinery (Republic of Kazakhstan). The study compares existing results, modeling
results based on the suggested method and experimental results obtained using an LGsetup of the Atyrau Oil Refinery. The deliverables demonstrate high efficacy and
excellence of the approach to the modeling of interconnected equipment (chemical and
technological systems).
