Reactor-regenerator System Joint Work Optimization in Benzene Alkylation with Higher Olefins Unit

Abstract

The work has been carried out to provide smooth operation of “reactor-regenerator” system as an important step in the problem of synthetic detergents production efficiency enhancing. Reasons which cause violation of HF-catalyst regeneration column regime have been identified. The ways of benzene alkylation rector and catalyst regenerator column joint work optimization have been proposed. Optimization consists of HF-catalyst optimal activity achievement with further system conversion in to the steady state, as well as probable failure date predicting with the possibility of column drainage in order to prevent it. The concept of the optimal activity has been introduced and positive effect achieved by its maintaining has been shown.
