Modeling of CSTR Reactor for Sodium Benzoate Production

Chukwuemeke. P Ukpaka, Ziebiye Zaccheaus Wilcox

Abstract


The mathematical model was developed for Continuous Stirred-Tank Reactor (CSTR) for the production of sodium benzoate from the reaction of sodium hydroxide and benzoic acid. The performance equation for the operation of CSTR was developed for the analysis of the reactor’s functional dimensions and parameters. The analysis of the reactor’s functional parameters was performed at molar ratio of benzoic acid to sodium hydroxide of 1.5 to 3.0 at intervals of 0.5 and at the same reactor operating conditions. The set of reactors’ modeled equations were solved simultaneously and then, simulated with the aid of MATLAB R2015a computer program. Similarly, for the CSTR conversion increases with increase in volume, space time and temperature, while the reactor space velocity heated generated per unit volume decreases with conversion. However, all the parameters increased with increasing molar feed ratio. Following the results obtained from the analysis, the production of sodium benzoate from sodium hydroxide and benzoic acid can be executed in CSTR depending on the capacity of production and conditions of operation. Finally, the optimum performance was observed at molar feed ratio of 3.0. Key words: Modeling, CSTR reactor, sodium Benzoate, production
