Difluoromethane (R32) as a refrigerant with zero ozone depletion potential and low global warming potential has received extensive attention in the refrigeration industry. The phase behavior of refrigerant/lubricant mixtures has a critical effect on the performance and operation safety in a compression-refrigeration system. Using the isochoric saturation method, the solubilities of refrigerant R32 in POE75 and in PVE68 lubricant were measured from 278.15 to 348.15 K. The results indicate that there is no sediment, no color change, and no stratification during the whole experiment. The nonrandom two-fluid equation was used to correlate the experimental data. For both oils, solubilities of R32 increase with the decrease of temperature and increase of pressure. R32 is more soluble in PVE than in POE. In addition, the Henry's constants were calculated for R32 in both oils at different temperatures.

“…Figure 3 is a comparison of the experimental data against data obtained from the literature 19 , where the average relative deviation and maximum deviation are 3.89% and 6.81%, respectively. Therefore, the experimentally obtained solubility of CO 2 in water agrees well with the literature values, and the accuracy of the apparatus meets solubility measurement requirements.…”

The static method of isochoric saturation was used to measure the solubilities of CO2, O2 and N2 in rocket propellant 5 (RP5) at temperatures ranging from 253.15 to 323.15 K in 10 K intervals and pressures ranging from 0 to 120 kPa. The measurement accuracy of the constructed experimental setup was verified by measuring the solubility of CO2 in water. The relative expanded uncertainty (k = 2) in the solubility data was less than 4.0%. The solubilities of CO2, O2 and N2 in RP5 increased with pressure. As the temperature increased, the solubility decreased for CO2 solubility and increased for O2 and N2. Henry's constants for the three gases in RP5 decreased over the experimental temperature and pressure ranges in the order of N2 > O2 > CO2. The measured solubilities of CO2, O2 and N2 could be fitted with a modified Krichevsky–Kasarnovsky equation, and the maximum deviation between the measured and calculated data was less than 8.04%, 7.03% and 6.18%, respectively.

“…Henry's coefficient is one of the important thermodynamic coefficients, which reflects the physical dissolution degree of the gas solute in the solvent. Henry's law [12,27] or the Krichevsky-Kasarnovsky equation [28] is usually used directly to estimate Henry's coefficient. The solubility used in these equations is physical.…”

The solubility of hydrogen sulfide in different mole ratios of ferric chloride and 1-butyl-3-methylimidazolium chloride ionic liquid (rFeCl3/[bmim]Cl, r = 0.6, 0.8, 1.0, 1.2, 1.4) at temperatures of 303.15 to 348.15 K and pressures of 100 to 1000 kPa was determined. The total solubility increased with the increase of pressure and the decrease of temperature. The solubility data were fitted using the reaction equilibrium thermodynamic model (RETM). The mean relative error between the predicted value and the measured value was less than 4%. Henry’s coefficient and the equilibrium constant of chemical reaction at each temperature were calculated. Henry’s coefficient first decreased and then increased with the increase of mole ratio, and increased with the increase of temperature. The equilibrium constant of the chemical reaction followed the same law as Henry’s coefficient. The chemical solubility was related to both Henry’s coefficient and the chemical equilibrium constant. H2S had the highest chemical solubility in FeCl3/[bmim]Cl at a mole ratio of 0.6 and a temperature of 333.15 K. The chemical solubility increased with the increase of pressure.
