Equilibria of binary guest mixtures

The phase equilibria data for binary guest mixtures are listed under the lighter component. For example, under the heading of binary guest mixtures of methane will be found data for methane + ethane, methane + propane, methane + isobutane, methane + n-butane, methane + nitrogen, methane + carbon dioxide, and methane + hydrogen sulfide. Concentrations are in mole percent or mole fraction in the gas phase, unless otherwise indicated. 

The subsection for binary guest mixtures of ethane will thus contain no methane, only mixtures of ethane and heavier (or noncombustible) components. As an indication of consistency the data tabulations for each binary pair are followed by a semilogarithmic plot of pressure versus temperature, where there is more than one data set. 

Gas impurities may have caused the systematic deviation of the Berecz and Balla-Achs CH4 + CO2 hydrate data from those of Unmh and Katz (1949) and Adisasmito et al. (1991) and for those reasons the former data are excluded.
