ABSTRACT

Gas-liquid critical properties of ethylene + hydrogen and propylene + hydrogen are measured in the olefin-enriched region by using a high-pressure view cell with direct visual observation. The critical temperature of the two systems decreases with increasing concentration of hydrogen, whereas the critical pressure increases. The Soave-Redlich-Kwong (PSRK) and group contribution equations of state are used to predict the critical points, and the results agree well with the experimental data.
