Grenzflächenspannung und Dichte von Ethanol in Kontakt mit Kohlendioxid

Fractionation technologies for liquid mixtures using dense carbon dioxide

“…Other sources of IFT data of pure water in contact with different gases, other than CO 2 , can be consulted in Dittmar et al [268]. Information regarding IFT data for ethanol in CO 2 and N 2 , are also available in Oei et al [264] and Dittmar et al [268]. No data for other aqueous mixtures in contact with CO 2 at elevated pressures were found in the literature.…”

Cross-Association Model for the Phase Equilibria and Surface Tensions of CO2−Methanol and CO2−Ethanol Mixtures

“…Comparison of the experimental − (symbols) and predicted (lines, from PC-SAFT combined with DGT) surface tensions of CO 2 −ethanol mixtures. Main plot: ●, 292.65K; ○, 313.15K; ◼, 334.15K; ◻, 354.65K; ----, 292.65K; , 313.15K; − −, 334.15K; - - -, 354.65K.…”

“…In SC−CO 2 extraction, as the pressure is very high and the surface tension is of small value, a full study on the temperature and pressure dependence of surface tensions of CO 2 −methanol and CO 2 −ethanol mixtures is very important for the intensification of mass transfer and heat transfer, as well as the simulation and design of the extraction process. However, only Oei et al, Dittmar et al, , and Sun and Shekunov have measured the surface tensions of CO 2 −ethanol mixtures thus far, and the concerned theoretical models have been rarely reported.…”
