Predicting component properties of soybean oil and its modeling as a hypothetical component
Abstract
The work presents the application of the method of contribution by groups of Marrero and Gani and the method of the constituent chemical fragments, in the determination of the critical properties, boiling temperature, vapor pressure and density of triglycerides and α-tocopherol, present in soybean oil. The results were applied in the modeling of crude soybean oil as a hypothetical component using the Hysys 8.8 simulator, based on a characteristic concentration profile. Applying the Attached Analysis tool, the thermo-physical properties of soybean oil were determined at temperatures between 20 ° C and 140 °C. By the fragment method, the vapor pressure of triglycerides (tripalmitin, tristearin, triolein, triliolein and trilonenin) and of the triglyceride mixture were determined; the parameters of the Antoine equation, and the vapor pressure curve of crude soybean oil are presented. The procedure can be a valuable tool in the simulation of processes for obtaining edible oils, as well as non-edible oils (biodiesel).
