“…Information is available concerning the vaporliquid equilibrium of three binary hydrogen-paraffin hydrocarbon systems at temperatures between 100°and 300°F. and at pressures up to 5000 pounds per square inch (5). Kay (8) determined the bubble point and dew point pressures and temperatures for three mixtures of hydrogen in a petroleum naphtha and found a marked minimum solubility with respect to changes in temperature.…”

“…Sattler (1940) measured the solubility of hydrogen in paraffinic, naphthenic and aromatic solvents and showed that it is a linear function of pressure up to 15.2 MPa. Dean and Tooke (1946) determined the solubility of hydrogen in various paraffinic compounds for temperatures from 3 1 1 to 422 K and pressures from 3.45 to 34.5 MPa. They reported an increase in the hydrogen solubility with temperature and pressure, but a decrease with the solvent molar mass.…”

“…The methods available for determining gas-liquid equilibrium can be grouped into static or dynamic methods. In static methods, the gas-liquid mixture is stirred with an electric stirring motor (Katz and Hachmuth, 1937), rocking mechanism (Dean and Tooke, 1946;Akers et al, 1954). or a magnetic stirrer (Legret et a]., 1981) in a closed cell until pressure and temperature reach equilibrium values.…”

Experiments were carried out to identify a solvent which has a high solubility and selectivity for methane relative to hydrogen at 295 K and pressures from 13.88 to 20.78 MPa. Binary solubilities with pure hydrogen and methane, and ternary solubilities with 73 mol% H, and 27 mol% CH, were measured at 295 K and for pressures from 6.99 to 20.78 MPa in various organic solvents. This gas mixture simulates hydrocracker and hydrotreater off-gases which are candidates for purification with an absorption-stripper. Of the solvents tested, 2.2.4-trimethylpentane (iso-octane). which showed very high methane solubility and a reasonable selectivity, and methylcyclohexane. which showed a very high selectivity and a reasonable solubility, are the best solvents for methane absorption.Correlations for hydrogen and methane as a function ofpressure and solvent solubility parameter were developed with the experimental solubilities. Binary interaction parameters for Peng-Robinson (Peng and Robinson. 1976) and SoaveRedlich-Kwong (Soave, 1972) equations of state were calculated with experimental solubility results. Prediction of gas solubility in a ternary system was compared with experimental and found to be satisfactory when experimental binary interaction parameters were used. Keywords: solubility, selectivity, binary interaction parameter, absorption-stripping, high pressure.he sponge oil absorption process (Mulvihill et al., 1964) T for selective absorption of light hydrocarbons in the presence of hydrogen has been used in petroleum refineries to purify high pressure hydrocracker off-gas typically containing 70 mol% H2, 25 mol% CH, and 5 mol% C2+. This off-gas stream at 13.88 to 20.78 MPa is normally cooled below 3 10 K to take advantage of higher methane solubility and lower hydrogen solubility at lower temperatures. When recovery of high purity hydrogen is not required, sponge oil absorption (sponge oil is defined generally as a hydrocarbon liquid which is nonreactive with the absorbed vapors, having a vapor pressure not greater than 10% of the vapor pressure of the vapors being absorbed (Haines, 1975)) can be more economic (Pruden et al., 1996) than other purification processes such as pressure swing adsorption, membrane separation and cryogenic separation. The purified hydrogen is available at high pressures and need not be compressed to feed to the hydrocracker recycle gas compressor. To itnprove the efficiency of the sponge oil absorption process, an optimum oil that selectively absorbs light hydrocarbons such as methane over hydrogen is desirable."Author to whom correspondence should be addressed. E-mail address: pruden@acs.ucalgary.ca Abundant literature has been published on experimental high pressure solubilities of hydrogen or methane in organic solvents. However, no literature could be found on high pressure solubility in a ternary system, where both hydrogen and methane are dissolved in organic solvents. Battino and Clever (1966) gave detailed information about various methods and apparatus, methods of expressing gas ...

“…En ésta, se observó que el peso molécular de la decalina fue el menor, en comparación a los otros dos solventes. Con base en los resultados anteriores, al disminuir la temperatura la solubilidad disminuyó, de acuerdo a varias publicaciones [78], [124]. Harrison et al [125] reportaron experimentalmente que al aumentar la presión a una temperatura constante, la fracción del hidrógeno en el líquido aumentó, de manera similar a lo obtenido en la presente investigación.…”

Otra manera de obtener esta constante es mediante el uso de ecuaciones de estado y con datos experimentales, como lo reportan Moysan et al [109] y Dean y Tooke [110].…”
