Production of high-purity ethyl acetate using reactive distillation: Experimental and start-up procedure

“…In a previous work, Tang et al [5] validated a set of parameter for an NRTL-HOC model with experimental data of pure, binary and ternary mixtures. Because the goodness of the model, this has been applied in subsequent investigations [12][13][14], and will be used in this work to describe phase equilibrium of the reactive system. Parameters of the thermodynamic model are summarized in the supplementary material.…”

“…Bhatia et al [12] proposed a technically optimized reactive distillation process for the production of isopropyl palmitate by palmitic acid esterification with isopropanol based on the experimental and simulation results attaining very high conversions. Lai et al [13] worked at experimental production of high-purity ethyl acetate using reactive distillation in a pilot-scale plant obtaining purity about 99.5 wt.%.…”

Biodiesel is a clean burning fuel derived from a renewable feedstock such as vegetable oil or animal fat. It is biodegradable, non-inflammable, non-toxic, and produces lesser carbon monoxide, sulfur dioxide, and unburned hydrocarbons than petroleum-based fuel. The purpose of the present work is to present an efficient process using reactive distillation columns applied to biodiesel production. Reactive distillation is the simultaneous implementation of reaction and separation within a single unit of column. Nowadays, it is appropriately called "Intensified Process". This combined operation is especially suited for the chemical reaction limited by equilibrium constraints, since one or more of the products of the reaction are continuously separated from the reactants. This work presents the biodiesel production from soybean oil and bioethanol by reactive distillation. Different variables affect the conventional biodiesel production process such as: catalyst concentration, reaction temperature, level of agitation, ethanol/soybean oil molar ratio, reaction time, and raw material type. In this study, the experimental design was used to optimize the following process variables: the catalyst concentration (from 0.5 wt.% to 1.5 wt.%), the ethanol/soybean oil molar ratio (from 3:1 to 9:1). The reactive column reflux rate was 83 ml/min, and the reaction time was 6 min.
