Establisment of regularities of changes in physical and chemical properties of alkylbenzenesulfonic acids on the feedstock composition

Abstract

The article presents the results of experimental study of samples of raw materials and products ofindustrial alkylbenzene production. The presence in dehydrogenation process feedstock of alkylaromaticcompounds which result in alkylation reactions with olefins, and then polymerizing in sulphonation step to form ahighly viscous component, which prevents diffusion of SO3 in the liquid phase. According to the results ofthermodynamic analysis of reactions in alkylbenzenes sulphonation process, reaction network and mathematicalmodel of film sulphonation reactor were developed. The sulphonation process performance dependence ontechnological modes of all stages of alkylbenzene production. Optimal technological modes of sulphonationreactor in dependence on the content of aromatic hydrocarbons in alkanes dehydrogenation reactor feed arerecommended
