Phase equilibrium experimental data for the CO2/glycerol system are reported in this paper. The measurements were performed using an in situ FT-IR method for temperatures ranging from 40 C to 200 C and pressures up to 35.0 MPa, allowing determination of the mutual solubility of both compounds. Concerning the CO2 rich phase, it was observed that the glycerol solubility in CO2 was extremely low (...

ThermoData Engine (TDE) is the first full-scale software implementation of the dynamic data evaluation concept, as reported recently in this journal. The present paper describes the first application of this concept to the evaluation of thermophysical properties for binary chemical systems. Five activity-coefficient models have been implemented for representation of phase-equilibrium data (vapo...

Mathematical analysis and simulation of a discontinuous rectification column was performed using an operational strategy during the start-up before reaching pseudo-stable state in operation. The mathematical model formulated focusing on equilibrium (ES) implementing MESH equations (M: Mass balance, E: Equilibrium thermodynamics, S: Stoichiometry relations, H: Enthalpy or heat balance) to provid...

Terpenes are important varietal compounds responsible for the characteristic aromas of alcoholic beverages. Reliable vapor–liquid equilibrium (VLE) data this class aroma in hydroalcoholic media is essential to understand their behavior during distillation and thus achieve a desired quality distilled products. In work, experimental measurements VLE ?-terpineol highly diluted ethanol–water mixtur...
