Critical Evaluation for Ethene Solubility in Hydrocarbon Fuels, Russian Crude Oils and Waxes for pressures greater than 0.20 MPa

Solubility of ethene in gasoline and kerosene's were reported by Hannaert et al.¹ for temperatures ranging from 233.15 K to 293.15 K expressed as an exponential function of the equilibrium ratio K = y₁/x₁ in which y₁, and x₁ are mole fractions in the gas, and liquid phase, respectively. It was possible to calculate mole fractions because the boiling fractions and densities of these hydrocarbons were measured and were associated with certain average molecular weights. In consequence, the results must be of lower accuracy because the true composition was actually unknown. The authors claimed accuracies ranging from 2% to 15%.

Hannaert et al.¹ also reported solubility of ethene in two types of Carbowax for a range of temperatures from 273.15 K to 353.15 K. As for gasoline and kerosene's, a similar exponential function was used to express the solubility results. Here also, the molecular weights of the Carbowax had been previously determined so that mole fraction solubility could be determined.

Both results of Hannaert et al.¹ are classified as tentative.

Chou and Chao² reported solubility of ethene in Fischer-Tropsch SASOL wax for pressures ranging from 1.016 MPa to 5.163 MPa and for temperatures 473.2 K and 533.1 K. The results are consistent and obey Henry's law.

These data are classified as tentative.

Safronova and Zhuze^3,4 reported ethene solubility in three Russian crude oils for three temperatures, 293 K, 323 K and 373 K for pressures to 20 MPa, in the form of modified Bunsen coefficients. In the first paper, published in 1958, some numerical results were reported and in the second paper, published in 1962, only graphical results were reported, for the same crude oils. Densities, viscosities and some analyses of the oils were also given. Even for identical conditions deviations between results were up to 9% from the two sources. Thus, the accuracy is probably of this order.

These data are classified as tentative.
