“…In contrast to this study, 41 the work of Hu et al 67 is mainly devoted to applied aspects such as intensification of the reactive distillation with participation of n-butyl acetate as a separating agent, which, according to authors' estimates, results in substantial decrease in power consumption for ethyl acetate synthesis (by up to 32%). The results of this study are largely based on analysis of the phase equilibria in the acetic acid ± ethanol ± ethyl acetate ± water system, thus illustrating the practical importance of data on the phase equilibrium in reacting systems.…”

“…The authors studied the esterification of acetic acid with ethanol in aqueous media at 313.15 K using various catalysts to intensify the recovery. Hu and colleagues [6] report the design of RD process for the production of ethyl acetate. Data on vapor-liquid equilibrium and vapor-liquid-liquid equilibrium at the temperature range 343.…”

a b s t r a c tSolubility, critical states and liquid-liquid equilibrium (LLE) data for the quaternary system acetic acid-ethanol-ethyl acetate-water and for the ternary subsystems acetic acid-ethyl acetate-water and ethanol-ethyl acetate-water were studied at 303.15 K and 313.15 K and atmospheric pressure. Binodal surfaces, binodal curves, tie-lines and compositions of critical points were determined. In order to construct the binodal surfaces and critical curves of the quaternary system, five quaternary sectional planes with several different ratios of concentration of acetic acid to ethanol were studied. Experimental LLE data were compared with the values calculated by UNIFAC and NRTL models, and it was found that the experimental and calculated data are in good agreement.

“…The separation can be enhanced by physical methods: the addition of selective solvent (azeotropic reactive distillation [3], reactive extractive distillation [9]) or by changing operation conditions (pressure-swing RD [4]). Chemical methods are based on employing an auxiliary chemical reaction to remove the by-product of the main reaction while obtaining another valuable product.…”

Multi-Objective Assessment of Heat Pump-Assisted Ethyl Acetate Production

Multi-objective (energy–economic–safety) assessment of ethyl acetate production involving a heat pump is presented in this paper. The heat pump is designed to intensify ethyl acetate separation and to reduce the total operating cost. Two ethyl acetate production pathways are upgraded using a heat pump, conventional process and reactive distillation column with a separation unit. Detailed process models including the heat pump environment have been compiled and optimized in the Aspen Plus software. Both benefits and drawbacks of including the heat pump in the processes are evaluated using three different points of view: process energy, economics, and safety. As a result, using a heat pump is highly recommended in both conventional process and reactive distillation column with a separation unit. As a higher level of process integration is achieved using a heat pump, economic aspects are improved; however, safety aspects deteriorate. The final decision on the suitability of using a heat pump depends on whether it is proposed for an existing plant, or a completely new plant is designed. In a new plant, the concept of a thermally coupled process (reactive distillation column with a stripper column) has been proven to be the most promising.
