    Thermodynamic properties of l-butene (1955)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 1 (1955), S. 210-214

    ISSN: 0001-1541

    Notes: The thermodynamic properties of 1-butene have been calculated over a temperature range of 32° to 480°F. and at pressures up to 1,000 lb./sq. in. abs. These properties were determined from vapor-pressure, volumetric, heat-capacity, and latent-heat of vaporization data through the application of rigorous thermodynamic relationships. The calculated data have been found to be internally consistent. The enthalpy values are believed to be accurate to within ±0.5 B.t.u./lb. and the entropy values to ±0.0005 B.t.u./(lb.) (°R.).

    Evaluation of the heat requirements in batch distillation operations (1957)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 3 (1957), S. 391-394 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A rigorous method is presented for the evaluation of the heat requirements in binary batch fractionations which involve negligible column hold up. The method, in which the additional variables of the discontinuous process are taken into account, is a modification of the methods of Ponchon and Savarit for continuous operation. Two examples, one for a fractionation in which the composition of the product is constant and the other in which the reflux ratio is constant, are given as illustrations of the method.The application of the method permits more accurate evaluation of reboiler and condenser heat loads and, in turn, better design.

    Notes: Thermodynamic properties of n-hexane have been calculated over a temperature range of 32° to 540°F. and up to a pressure of 600 lb./sq. in. abs. These properties were determined from vapor pressure, volumetric, heat capacity, and latent heat of vaporization data through the application of rigorous thermodynamic relationships. The calculated data have been found to be internally consistent. The enthalpy values are believed to be accurate to within 0.5 B.t.u./lb. and the entropy values to 0.0005 B.t.u./(lb.)(°R.).

    Liquid phase activity coefficients and standard state hypothetical liquid fugacities for hydrocarbons (1962)

    Notes: One method of predicting vaporization equilibrium ratios for the components of a multicomponent mixture is through the use of standard state liquid fugacities, standard state vapor fugacities, liquid phase activity coefficients, and vapor phase activity coefficients. The relationship among these variables will be shown.It is the purpose of this paper to present a method for evaluating the fugacities of the components of a multicomponent liquid mixture which is in equilibrium with its vapors; to present a method for evaluating the standard state fugacities of hypothetical liquids and to disclose these values for methane and ethane up to a reduced temperature of 1.6 and values for propane up to a reduced temperature of 1.3; to present the coincident derived values of the vaporization equilibrium constants, Z factors, and solubility parameters; and to show correlations of these values.

    Profiles of laser-created cavities on metal surfaces (1969)

    Notes: Metal surfaces of titanium, aluminum, copper, lead, and zinc were irradiated by a 25 joules pulsed laser with an energy flux ranging from 106 to 108 cal./(sq.cm.) (sec.). The resulted cavities were sectioned, polished and measured to compare with the isotherms computed from several heat conduction models. Reasonable agreement was found between the experimental cavity diameters at the interface and those calculated from the disk source model. Also, a graphical correlation between the cavity depth and its interface diameter is presented.

    Theorem of corresponding states applied to saturated liquids and vapors (1956)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 2 (1956), S. 354-359 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The existence of a single generalized compressibility-factor relationship for univariant systems has long been denied because reduced variables do not provide a generalized vapor-pressure relationship. The present study demonstrates that a saturation curve depends on the ability of the theorem of corresponding states to correlate the reduced temperature as a function of reduced, pressure and the critical compressibility factor. Saturation curves for both the liquid and the vapor phases are established from compressibility data on a variety of systems, substantiating this conclusion.The compressibility factors of saturated mixtures are correlated with pseudoreduced properties based upon Kay's pseudocritical concept. The results indicate that the compressibility factors of saturated liquid mixtures can be predicted with reasonable precision over the entire two-phase region. For pseudoreduced isotherms of unity and above, the same isotherms apply to both phases and are approximately consistent with published compressibility charts for pure gases.

    Differential heats of condensation and enthalpies of saturated liquid hydrocarbon mixtures (1956)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 2 (1956), S. 389-392 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: By use of saturated-vapor enthalpies determined by accepted procedures in conjunction with differential latent heats of condensation, the saturated-liquid enthalpies are established for the system methane-ethane at 200, 400, and 600 lb./sq. in. abs. and for the system ethane-n-butane and propane-n-butane at the two lower pressures. Where comparison is possible, the liquid-enthalpy values obtained by this method are in general agreement with those previously determined by Edmister and Canjar. The procedure used is thermodynamically rigorous and may be applied to any binary mixture, provided the Benedict-Rubin-Webb equation of state is valid in the vapor phase and P-V-T-x data are available.

    Notes: The derived thermodynamic properties of acetylene have been determined over a temperature range of 32 to 500°F. and up to pressures of 2,000 lb./sq. in. abs. The data were calculated from vapor pressure, volumetric, and heat-capacity data by the use of rigorous thermodynamic relationships. The calculated data were found to be internally consistent. The enthalpy values are believed to be accurate within ±1.0 B.t.u./lb. and the entropy values to ±0.001 B.t.u./(lb.)(°R.).
