Phase behavior of olive and soybean oils in compressed propane and n-butane

Abstract: -The aim of this work is to report the experimental data and thermodynamic modeling of phase equilibrium of binary systems containing soybean and olive oils with propane and n-butane. Phase equilibrium experiments were carried out using the static synthetic method in a high-pressure variable-volume view cell in the temperature range from 30 to 70 o C and varying the solvent overall composition from 5 to 98 wt%. Vapor-liquid, liquid-liquid and vapor-liquid-liquid phase transitions were observed at relatively lo… Show more

“…Nevertheless, carbon dioxide is not the only gas whose properties seem to be adequate for biocatalysis (Kao, Ekhorutomwen, & Sawan, 1997). For instance, the comparable dielectric constant of propane and n-butane to carbon dioxide (Habulin & Knez, 2001;Oliveira, Feihrmann, Rubira, et al, 2006), and the fact that much higher pressure phase transition values are generally found in systems formed by carbon dioxide with high molecular weight compounds than when using propane and n-butane, suggest that propane and n-butane may also be suitable as reaction media for enzymecatalysed bioconversions (Ndiaye et al, 2006).…”

“…triglycerides) compounds support a firm belief that propane may also be suitable as a reaction medium for enzyme-catalyzed bioconversions (HABULIN; KNEZ, 2001;CHEN;YANG, 2000). Besides, compared to higher homologue hydrocarbons and liquid solvents at ambient conditions, the use of propane offers the advantages of low separation costs and also solvent-free products (LANZA et al, 2005;NDIAYE et al, 2006a;NDIAYE et al, 2006b). …”

“…Typically, the required properties for evaporation as a function of the temperature of the remaining fuels are quite rare in the literature according to the best knowledge of the authors. Therefore, only rapeseed and soybean oil were investigated from evaporation point of view, using the following data [25,[31][32][33][34][35] power law, and Arrhenius. Figure 3 shows the SMD characteristics of the investigated fuels at 20 °C and under atmospheric pressure.…”
