Heat Integration of an Industrial Unit for the Ethylbenzene Production

This paper presents both the results of a study existing heat exchanger network (HEN) an industrial unit for ethylbenzene (EB) production by alkylation benzene with ethylene, and analysis four different HEN retrofit projects carried out using process integration methods. The project modernization was classical methods Pinch analysis. For this case, value ΔTmin is determined, which limited technological conditions process. Additionally, two pump (HP) options joint HP are under consideration. economic each out. It shown that best will be obtained when implementing project. As result, steam consumption reduced 34% carbon dioxide emissions decreased same amount.
