Saturation of high pressure gases with low volatile solvents: experiments and correlation

Abstract

The solubilities of methanol, toluene, acetone, n-heptane or n-nonane in nitrogen, methane or carbon dioxide are determined at temperatures of 240 K < T < 283 K and at pressures 0.4 MPa < p < 12 MPa with the dynamic continuous accumulative method. Second cross virial coefficients are calculated from the experimental data. The Redlich-Kwong-Soave equation of state is used for the correlation.
