摘要: Abstract Zhang et al. [1] presented a prediction of phase equilibria in the CO2–C2H5OH–H2O system at 308–338 K and 10–17 MPa using SAFT equation state (EOS) with pure-component parameters fitted to properties binary interaction subsystems same temperature range. conclude that “compared earlier works by different authors, for ternary CO2–C2H5OH–H2O, EOS seems be best both correlation prediction”. This letter comments on (1) introduction, (2) description SAFT, (3) fitting procedure parameters, (4) equilibria, (5) (6) conclusions original paper.
