Measurement and modeling of high-pressure (vapour+liquid) equilibria of (CO2+alcohol) binary systems

High-pressure (vapour+liquid) equilibria for ternary systems composed by {(E)-2-hexenal or hexanal+carbon dioxide+water}: Partition coefficient measurement

“…The discrepancies observed between the experimental values from this study and from the those reported in literature for the liquid phase was <6%, and for the vapour phase was <0.5%. As it can be seen from figure 2, the results reported by Gutierrez et al [36] deviates significantly from the literature, especially for the vapour phase mole fraction at pressures below 5 MPa.…”

“…Gutierrez et al [36] used a manual gravimetric sampling method for the vapour phase. With this method, especially at low pressures, high uncertainties of ethanol content in the vapour phase were detected due to the amount of sample that can be withdrawn from the equilibrium cell without altering significantly the equilibrium pressure inside the cell.…”

“…Originally, the experimental apparatus was used to measure high-pressure VLE of (CO 2 + alcohol) binary systems using the static-analytical method in which the phase compositions were determined gravimetrically as described in a previous work [36]. The modifications of the experimental set up consisted in the implementation of a Rapid Online Sampler-Injector (ROLSI™, Armines/CEP/TEC, Paris, France) for the vapour phase [37].…”

Estimating the liquid properties of 1-alkanols from C5 to C12 by FT-EoS and CP-PC-SAFT: Simplicity versus complexity

“…Lines -modeling of CP-PC-SAFT with k 12 = 0.057, l 12 = 0.012. Literature data: VLE[79][80][81][82][83], densities[83,84].…”

Effect of the ethoxy groups distribution on the phase behaviour of the binary systems carbon dioxide CO2 with industrial non-ionic surfactants (CiEOj)

“…However, if CO 2 is combined with surfactants molecules, an effective removal of insoluble substances could be produced [13][14][15]. In a previous work [8], it was established that ethoxylated surfactants (C i EO j ) could be combined with carbon dioxide to be used for dry-cleaning purposes.…”
