| 摘 要： | Experimental study has been conducted to determine the solubility of natural gas in liquid at temperatures of 293.15, 298.15, 303.15 and 313.15 K at atmosphere pressure. Ethanol, n-bexane and n-heptane were selected as solvents in the experiment. The solubility data of methane in the mixing solvents were determined and the experimental data were calculated with the PR and PRSV equation of state(EOS). The calculated average absolute deviations for the two kinds of ternary systems CH4/n-C6H14-C2H6O and CH4/n-C7H16-C2H6O are 1.92% and 1.85% for PR EOS and 2.11% and 1.87% for PRSV EOS, respectively.
