    The Excess Enthalpy of (Steam+Ethane) in the Supercritical Region up to T=699.4 K and p=25.3 MPa (2000)

    Notes: Abstract Flow calorimetric measurements of the excess molar enthalpy H E m of (0.5H2O+0.5C2H6) in the supercritical region carried out at temperatures from 573.7 to 699.4 K and at pressures in the range 5.05 to 25.3 MPa are reported. The measurements are fitted by a two-reference-fluid corresponding-states model which gives a good representation of the excess enthalpies up to the highest pressure.

    Specific Enthalpy Increments for Butan-1-ol at Temperatures from 423.2 to 623.2 K and Pressures to 10.2 MPa (2000)

    Notes: Abstract Measurements of specific enthalpy increments for butan-1-ol are reported. A counter-current water-cooled flow calorimeter was used to measure 109 enthalpy increments over the temperature range of 423.2 to 623.2 K at pressures from 0.1 to 10.2 MPa. Extrapolation of the gas phase measurements to zero pressure gave values in close agreement with pure-component ideal-gas enthalpies calculated by extrapolation of data on the lower alcohols. Values of the specific enthalpy of vaporization derived from the measurements are in agreement with other work and are well fitted by a modification of the Watson equation. A method for the calculation of the two-phase enthalpy-pressure envelope is described.

    Excess enthalpies for (water + methane) vapor up to 698.2 K and 12.6 MPa (1984)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 30 (1984), S. 386-393

    ISSN: 0001-1541

    Notes: A new flow mixing calorimeter has been used to make measurements of the excess enthalpy of water vapor + methane at temperatures up to 698.2 K and pressures up to 12.62 MPa. Tests on the calorimeter and consistency tests on the measurements suggest that the results are free from significant error. The measurements are fitted to an equation from which excess volumes and compressibility factors for the mixture are calculated.
