Feasibility of integrated batch reactive distillation columns for the optimal synthesis of ethyl benzoate

Abstract

The synthesis of ethyl benzoate (EtBZ) via esterification of benzoic acid (BeZ) with ethanol in a reactive distillation is challenging due to complex thermodynamic behaviour of the chemical reaction and the difficulty of keeping the reactants together in the reaction zone

A novel split-reflux policy in batch reactive distillation for the optimum synthesis of a number of methyl esters

“…The model is an equality constraint. The BRD column (Figure 1a) model is same as that presented in Aqar et al (2016aAqar et al ( , 2017b except that the reaction kinetics and phase equilibria for both DeC, ScA, and BeZ esterification reactions. Different levels of simplifying assumptions are typically made for the process models such as the vapour holdups and column hydraulics are negligible, and ideal vapour liquid equilibrium is assumed.…”

Dynamic Simulation of a Reactive Distillation Column for Ethyl Acetate Production: Optimization of Operating Conditions Using Response Surface Methodology

“…Negligible side reactions and byproduct formation, vapor hold-up, adiabatic and perfect mixing on plates, constant pressure, and ideal vapor phase assumptions were used for simulation of the designed RD column. In general, azeotrope formation in the column is accomplished as a result of the increase in the conversion level due to the removal of the products continually (Aqar et al, 2017). The components are complemented by a minimum boil-up ratio for the prevention of azeotrope between reactive and products.…”

“…Therefore, many academic and commercial studies have been performed to utilize the benefits of RD (Segovia-Hernandez et al, 2015;Carrera-Rodriguez et al, 2014;Georgiadis et al, 2002;Petchsoongsakul et al, 2017). RD applications are used in many different chemical processes such as esterification which is an exothermic and equilibrium-limited reaction, regulated by chemical equilibrium in the presence of water as a by-product (Aqar et al, 2017;Zhang et al, 2019). In a RD process, the reactor is also a separator.…”
