Numerical simulation of a flow mixer for a radial type chemical reactor

Abstract

© Published under licence by IOP Publishing Ltd. In this work, we performed mathematical modeling of internal elements for mixing the reaction flows. The reactor of the dehydrogenation of ethylbenzene to styrene process was studied. A variant of a radial type reactor in which the gas flow is from the bottom up is considered. Ethylbenzene and steam were selected as components for mixing. Ethylbenzene is supplied to the mixer at a temperature of about 600°C, and steam at a temperature of about 700°C. Three design cases for the internal devices of the mixer are considered. The analysis of the gas mixture parameters, such as volume fraction and average temperature, at the outlet of the mixer was carried out. The cases with the best mixing of the components are determined.
