The suitability of the experimental data for modeling was established by performing the Herington area test, Van Ness test, and mean absolute deviation test. Binary interaction parameters necessary for process modeling were derived through the regression of the VLE data for Wilson, NRTL, and UNIQUAC activity coefficient models with a suitable objective function. VLE data in the form of T-x, y plots indicates no formation of azeotropes for all pairs.1 aBhoi, Bharat, R.1 aMali, Nilesh, A.1 aJoshi, Sunil, S.  uhttp://library.ncl.res.in/content/isobaric-vapor-liquid-equilibrium-data-binary-systems-anisole-methyl-acetate-ethyl-acetate-n01848nas a2200217   4500008004100000022001400041245008600055210006900141260000800210300001100218490000800229520110200237653003501339653002601374653003301400653002201433100002001455700002101475700002101496856011301517       2020                        eng d  a0255-270100aIntensified reactive distillation configurations for production of dimethyl ether0 aIntensified reactive distillation configurations for production   cMAR  a1078240 v1493 a<p>The combustion properties of dimethyl ether (DME) are similar to the conventional fuels; hence it is being used as a promising green energy source. The conventional method of DME production by methanol dehydration is highly energy consuming due to the use of a series of distillation columns. In the present study, an energy efficient reactive distillation configuration is proposed for DME production which leads to higher methanol conversion with less energy requirement as compared to reported configurations. The reactive distillation (RD) and dual reaction zone reactive divided wall column (RDWC) were analyzed using steady state ASPEN simulations. Subsequently, all the design parameters were optimized by sensitivity analysis to minimize the Total Annual Cost (TAC) of the configuration. The results showed that the RD column is more energy efficient than RDWC as it requires 10.68 % less TAC. The proposed RD and dual reaction zone RDWC configurations were found to have less specific energy requirements and less cost per kg of DME than any other configuration reported earlier.</p>

	The isobaric vapor-liquid equilibrium (VLE) data of the systems (ethyl acetate + toluene), (n-propyl acetate + toluene), (iso-propyl acetate + toluene), (toluene + iso-butyl acetate), and (toluene + iso-amyl acetate) were measured under the isobaric condition at 92 kPa using a glass dynamic recirculation apparatus. The experimental VLE data was correlated by NRTL, Wilson, and UNIQUAC activity coefficient models to account for the nonideality. The binary interaction parameters of the models were obtained by regressing the experimental data using the maximum likelihood objective function. The thermodynamic consistency of the experimental data was checked by using the Van Ness test and the infinite dilution test. Extrapolating the activity coefficient at infinite dilution was done by regressing the experimental data with an extended Redlich-Kister equation. The NRTL, Wilson, and UNIQUAC models exhibited a maximum root-mean-square deviation less than unity for temperature and vapor mole fraction. Additionally, it is worth noting that no azeotrope was identified in the VLE data in this study.</p>
