Ethyl acetate is intensively used as a solvent for paints, coatings, resins, inks, main ingredient in different fragrances and flavors for consumer products and decaffeination. An assessment of the ethyl acetate esterification process for different process intensification techniques was studied to identify the several advantages over the traditional process. Experimental and simulation details for individual ethyl acetate production process and coproduction process with n-butyl acetate or isopropyl acetate are discussed. Simulation studies analysis shows the comparison of various mathematical models and the identification of the most commonly used model for different process simulators. This review focuses on ethyl acetate process intensification techniques including Reactive distillation, pervaporation assisted reactive distillation, pressure-swing reactive distillation, reactive dividing wall columns, reactive extractive distillation, microwave reactive distillation, reactive chromatography. The effect of various process parameters i.e. ethanol flow rate, acetic acid flow rate, choice of a homogeneous and heterogeneous catalyst, reflux ratio, feed tray position, the total number of trays, types of entrainer, condenser and reboiler duties on ethyl acetate purity, overall production rate, energy consumption and total annual cost were discussed. Reactive distillation overcomes chemical equilibrium limitations, saving energy and ensuring economic effectiveness by reduced capital investment. [ABSTRACT FROM AUTHOR]
