“…Karwat's value 2 of the solubility of propane in the oxygen-rich liquid phase (0.98 % at T ) 90 K) is not consistent with solubilityversus-temperature trend determined by our study; the solubility is underestimated compared to our value. The McKinley and Wang datum published in 1960 3 is consistent with values obtained by extrapolation of our model to lower temperatures; the deviation of around 13 % is agreeable. Finally, the curve calculated by Lassmann gives solubility values largely lower than the values calculated in our study; significant positive deviations are observed over the whole range of temperature.…”

“…A few values of the solubility of propane in liquid oxygen have been published and are listed in Table 1. [1][2][3][4] Important discrepancies between the different published values can be observed. Furthermore, the temperature ranges mentioned in these references are relatively limited [at temperatures from (77 to 90) K] and do not correspond to the whole operation field of ASUs, even if T ) 90 K is close to important ASU operating conditions.…”

Equilibrium Data for the Oxygen + Propane Binary System at Temperatures of (110.22, 120.13, 130.58, and 139.95) K

vapor-liquid equilibrium (VLE) data for the (O 2 + C 3 H 8 ) binary system were measured using a "static-analytic" method coupled to a gas chromatograph analysis at temperatures of (110.22, 120.13, 130.58, and 139.95) K. Parameters of a proposed thermodynamic profile were adjusted on the basis of experimental VLE data determined in this work, allowing a complete isothermal phase diagram for this hazardous system to be obtained. The vapor-liquid-liquid equilibrium (VLLE) thermodynamic behavior was predicted by modeling and then confirmed by visual observations. On the basis of this work, solubility values of propane in liquid oxygen can be deduced for both the propane-lean and propane-rich liquid phases at temperatures above the melting temperature of pure propane. The device allowing these data to be measured for such a hazardous mixture is also presented, as are the accuracies of the measurements. Experimental SectionChemicals. Oxygen (CAS no. 7782-44-7) was obtained from Air Liquide with guaranteed mole fraction purity > 0.999995. Propane was provided by Messer with certified mole fraction purity > 0.9995.Apparatus. The method used in the present work was of the "static-analytic" type with a rapid online sampler-injector (ROLSI; Guilbot et al. 7 ) pneumatic microsampling device and online gas chromatographic analyses. 7,8 A 12 cm 3 Hastelloy C276 equilibrium cell was specifically designed and built in order to withstand pressures up to 300 MPa in case of accidental internal ignition of the oxygen-propane mixture. 6 Inside the cell, temperature and pressure were measured with uncertainties † Part of the "Sir John S. Rowlinson Festschrift".

“…14 The visual method was used to get the solubility 0.0013 (77.3 K) 15 and 0.0275 (90 K). 16 Using IR absorption detection, the solubility was reported as 0.0340 (90 K). 17 Solubilities in liquid nitrogen in the range of 0.0039 (77.4 K) to 0.0059 (80.1 K) have been obtained using IR spectroscopy for detection.…”

C–H Infrared Absorption and Solubility of Ethylene, Propyne, 2-methyl-2-butene, and 2-methyl-1, 3-butadiene (Isoprene) in Liquid Argon Solutions

The solubility of ethylene (HC=CH), propyne (CH-C≡C-H), 2-methyl-2-butene (CH-CH=C(CH)), and isoprene or 2-methyl-1, 3-butadiene (HC=C(CH)-CH=CH) in liquid argon has been measured using mid-infrared and near-infrared (NIR) absorption. Spectra were recorded in the C-H infrared (IR) region. Spectra were obtained at increasing solution composition until the magnitude of the integrated absorption band reached a maximum value, indicating a saturated solution. The approximate experimental solubilities are: (600 ± 100) ppm at 92 K for ethylene, (22 ± 9) ppm at 100 K for propyne, (9 ± 5) ppm at 100 K for 2-methyl-2-butene, and (12 ± 2) ppm at 86 K for isoprene. The experimental solubility values at the corresponding temperature were used with solubility parameters of two separate models: the perturbed-chain statistical associating fluid theory (PC-SAFT) and the regular solution theory. Solvent-solute interaction parameters k (PC-SAFT) and [Formula: see text] (RST) were obtained for each solute in the presence of argon as the solvent. Data from experimental measurements are important for more realistic simulations of solubility of solids in cryogenic liquids.
