| Izvleček: | Title screen The patterns of deactivation of liquid reaction media during the formation of highly viscous components, along with the mechanism and chemistry of hydrocarbon conversions in multicomponent feedstock, as well as the kinetic and hydrodynamic parameters of the process, were considered. A mathematical model was developed that takes all these factors into account. The reliability of the results obtained from numerical modeling of the alkylbenzene sulfonation reactor with SO₃ was confirmed by their strong agreement with industrial data collected from an operating alkylbenzene sulfonic acid production facility over an extended period. Using the developed mathematical model, an optimal set of design characteristics for the alkylbenzene sulfonation reactor was determined. Modifying the reactor design by increasing the diameter of the reaction tubes from 25 mm to 43 mm and reducing their number from 120 to 40 while maintaining a constant reaction volume led to a 45.5 % increase in the duration of the reactor's washing cycle Текстовый файл AM_Agreement |
