Aspen HYSYS was used to investigate several aspects of process design for benzene nitration. In this study, the frequency factor (ko) and the activation energy (Ea) for benzene nitration wereg iven from the literature. Calculations of chemical and physical properties were performed automatically on Hysys using the NRTL and UNIQUAC Thermodynamic models. Some aspects of process design were studied, namely: (1) the effect of temperature on the conversion of reactions, (2) the effect of the ratio of sulphuric acid to nitric acid on the synthesis of nitrobenzen in the reactor, and (3) the effect of reactor arrangements (parallel and series) on reaction conversion. The results showed that the peak ofconversion that could be achieved on a single reactorwas96.9% at a ratio of sulfuric acid: nitric acid = 3.5 and a temperature of 50ºC. However, based on this study, it is suggested that the most favorable conditions for nitration of benzene in an isothermal reactorare 50°C and a sulfuric acid:nitric acid ratio of about 2.5 to 3.
