The search of new renewable fuels and the interest finding uses for abundant subproducts many industrial processes have prompt Eni S.p.A to develop a technology producing biofuels from glycerol. One compounds involved in this process is 2-ethyl-4-ethoxymethyl-1,3‑dioxolane (PrEDO). In paper their temperature - vapor pressure curve has been determined experimentally as well binary vapor–liquid e...

The esterification reaction between acetic acid and butanol was investigated in a reactive distillation column. The thermodynamic aspects of considered system are discussed, equilibrium constant, vapor pressures and UNIQUAC interaction parameters were investigated. Reactive distillation experiments were carried out to provide high purity butyl acetate. For this purpose, a 2 m column with nonrea...

The determination of the existence and composition of homogeneous azeotropes is important both from both theoretical and practical standpoints in the analysis of phase behavior and in the synthesis and design of separation systems. We present here a new method for reliably locating any and all homogeneous azeotropes for multicomponent mixtures. The method also veri es the nonexistence of homoge...

In this study, the experimental results exhibit that the mixture of water + acetic acid + methyl acetate + pxylene has interesting phase behaviors of vapor-liquid equilibrium (VLE) and vapor-liquid-liquid equilibrium (VLLE) under pressure of 101.32 kPa. The VLE and VLLE data were obtained with a condensed-vapor-phase-recirculating still as described in the text. The experimental data are useful...

There is a growing interest in the search of clean, sustainable and renewable energy sources. Among them, the use of bio-diesel from vegetable oils is being considered. The knowledge of the phase equilibrium in mixtures found in the bio-diesel production is essential for the correct design and operation of the process. However, there is still a lack of information about the parameter values for...

The original composition of Laguocuo Salt Lake was found in the mirabilite area 15 °C isothermal phase diagrams Li+, Na+, K+//Cl−, SO42−-H2O system. Four phases comprise evaporation procedure. first stage is unsaturated except for carbonate. second made up sodium chloride, mirabilite, and borax precipitate simultaneously, where halogenation rate 31.58%, water loss 68.32%. penultimate step lithi...
