Abstract

In this work, we considered the results on the modeling of the industrial catalytic alkylation process, one of the terminal stages in the production of linear alkyl benzene sulfonates (LAS) used as the basis for the synthesis of synthetic detergents. Taking into account the experimental data obtained under regular operational conditions of alkylation unit at the Linear Alkyl Benzene and Linear Alkyl Benzene Sulfonates (LAB-LAS) Plant of OOO Kirishinefteorgsintez (OOO KINEF), we developed a scheme of chemical reactions for the purpose of creating the kinetic model for the alkylation process. The kinetic parameters of this model were identified by solving the inverse kinetic problem under the lack of necessary experimental data, so we had to reduce the number of estimated kinetic parameters with the use of thermodynamic data. The software model of this process permitted us to calculate quite precisely the material and heat balances of the reactor and also to study the influence of changes in different technological parameters on the effectiveness of the process.
