Dynamic Modelling Of Industrial So2 Oxidation Reactors Part I. Model Of ‘Hot’ And ‘Cold’ Start-Ups Of The Plant, Krzysztof J. Gosiewski
Krzysztof Gosiewski
The paper describes a comparison of some results computed using a mathematical dynamic model of a single reactor bed with real temperature unsteady state transients, measured in a large industrial scale SO2 oxidation reactor. Problems of the dynamic modelling of complete oxidation plants, including a heat exchange section and a start-up installation are discussed in the next section of the paper. As a basis for comparison some start-up dynamic transients were analysed. Tha analysis shows that the model (two-phase model for heat transfer and homogeneous model for mass transfer) is sufficient for qualitative analysis of the problem. The problems of …

The results are presented of a computer simulation of a reverse-flow reactor. The results are compared with experimental data quoted by other workers. The necessity to take into account gas-to-catalyst heat transfer is stressed, so that quantitatively correct predictions may be obtained using the model. A brief description is given of the way flow reversal has been incorporated in the model, and the possibility of the accumulation of errors occurring during the calculations is mentioned. It is shown that the one-dimensional heterogeneous model of the bed makes it possible to analyze the process with an accuracy sufficient for the preliminary …
