Abstract

The presented paper is devoted to research on stability of alkylation and sulphonation units joint work in alkylbenzene sulphuric acid manufacturing. The reasons of equipment unstable operation and product quality deterioration in the stages of benzene alkylation with olefins and alkylbenzenes sulphonation were determined. Using the developed mathematical models of these processes uncontrolled temperature rise in the bottom of HF-catalyst regeneration column forecasting was carried out. Study of sulphonation and alkylation units stability in dependence on aromatics flow rate in alkylator was also performed.
