“…The needle was dried with a soft paper tissue before the sample was introduced into the 2 mL analysis vial (HP 5182-0714) containing the compound used as the internal standard. Figure 2 shows the experimental ternary equilibrium data at the four temperatures studied here, together with LLE data reported by literature [10,11].…”

“…These vials were filled up to ~90% of their volumes, to maintain the vapor space at minimum. Then the vials were placed in a water bath jacket thermostatted at (303.15 ± 0.05) K [14]. Uniformity of temperature within the vials was maintained by continuous agitation of the mixtures samples with the multipoint magnetic stirrer (SBS, model A-04, SBS Instruments S.A., Spain) placed under the water bath.…”

The phase equilibrium data for methanol + ethanol + isooctane systems were obtained at 303.15 K. Data for methanol + ethylbenzene + isooctane system were taken from literature. The effect of ethanol addition on the system equilibrium was investigated at the same temperature. The distribution curves for ternary and quaternary system was analyzed. The experimental results for ternary systems were correlated with UNI-QUAC and NRTL equations. For the ternary systems studied here, the NRTL equation is more accurate than the UNIQUAC. The equilibrium data for the three ternary systems were used to determine interactions parameters for the UNIQUAC equation. For the quaternary system, the experimental data can be fitted more accurately to UNIQUAC equation than by the UNIFAC method.

“…In the last decade there has been a growing demand for the use of oxygenated compounds to produce unleaded gasoline [4] - [7]. Gramajo de Doz et al [8] analyzed the equilibrium phases of the systems containing hydrocarbons (benzene, isooctane, toluene, or cyclohexane) and oxygenated compounds (methanol, ethanol, or methyl tert-butyl ether), due to the physical and chemical properties of methanol, as a candidate for an oxygenated fuel additive. However, methanol has partial miscibility with aliphatic hydrocarbons, but not with aromatic hydrocarbons.…”

Liquid balance - steam for methanol mixing - Benzen using the Peng Robinson and Van-Laar models

This paper is related to the procedure for calculating curves dew point and bubble point of a binary system, consisting of the methanol and benzene mixture to 45°C, using the Peng-Robinson cubic equation to calculate the fugacity coefficient of gas i in the mixture, and Van Laar model to calculate the activity coefficient of component i in the liquid mixture. Then a comparison between the theoretical data with the experimental data and later with the commercial simulator Hysys-Aspen, which applies the model of Wilson. The simulation was validated with experimental data,in addition to comparing the results with a commercial simulator.
