    Dielectric constants and Clausius-Mossotti functions for simple liquid mixtures: Systems containing nitrogen, argon and light hydrocarbons (1975)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 21 (1975), S. 283-289 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Dielectric constants and Clausius-Mossotti functions (CM) have been determined for selected pure components, binary mixtures, and ternary mixtures at temperatures between 91 and 115 K and pressures near saturation. Excess Clausius-Mossotti functions (CME) have been calculated from the pure fluid and mixture values.Mixture CME values are found to be generally less than 0.1% of the mixture CM values for systems containing only nonpolar species. Thus, dielectric constant measurements can be conveniently used as substitute density measurements for simple liquid mixtures. Methods have been developed to utilize dielectric constant measurements to accurately determine densities and heating values per unit liquid volume for liquefied natural gas mixtures.
