Thermal conductivity: Reduced state correlation for ethylene and its application to gaseous aliphatic hydrocarbons and their derivatives at moderate pressures

Gaseous Thermal Conductivity of Hydrogen Chloride, Hydrogen Bromide, Boron Trichloride, and Boron Trifluoride in the Temperature Range from 55 to 380 .degree.C

“…The thermal conductivity values were determined from the response of the cell with a reference gas of known thermal conductivity in the reference side of the cell and the gas whose thermal conductivity is to be measured in the sample side of the cell. The cell constant, b, is calculated as (3,4) E-Eref=b(l/kl/kref) (1) where E is the unbalanced voltage with the sample gas on one side and the reference gas on the other side of the thermal conductivity cell and k and kref are the thermal conductivity values of the sample gas and the reference gas, respectively. The value of b is determined by using a standard gas of known thermal conductivity and determining its E values with respect to the reference gas.…”

“…Accurate values of thermal conductivity of halogenated gases such as hydrogen chloride (HC1), hydrogen bromide (HBr), boron trichloride (BCD, and boron trifluoride (BF3) are required for engineering design purposes. A search of the literature indicated a few measurements of thermal conductivity for gaseous hydrogen halides and boron trihalides using different techniques (1)(2)(3)(4)(5)(6)(7)(8). The present paper reports experimental thermal conductivity values of hydrogen chloride, hydrogen bromide, boron trichloride, and boron trifluoride in the temperature range from 55 to 380 °C at 1 atm using a differential hot-wire technique.…”

Evaluation of Thermal Conductivity of Gases at Atmospheric Pressure through a Corresponding States Method

“…Roy and Thodos , reported different functional forms and group contributions for evaluation of this part of reduced thermal conductivity for the chemical families as reported by Poling et al as “ Saturated hydrocarbons; Olefins; Acetylenes; Naphtalenes and Aromatics; Alcohols; Aldehydes, Ketones, Ethers, and Esters; Amines and Nitriles; Halides; and Cyclic compounds ”. Application of low-pressure gas viscosity, heat capacity at constant volume, universal gas constant, molecular weight, acentric factor (ω), and reduced temperature to evaluate the thermal conductivity of gases was studied by Chung et al , The effects of pressure have been also taken into account in several efforts introducing the excess thermal conductivity correlations − or using the transport property prediction method (TRAPP). , …”

Molecular Transport Properties of Fluids. Chemical Engineering Fundamentals Review

“…The partition functions for normal liquids were applied by Blomgren (77) to the absolute rate theory expression for viscosity with satisfactory results for argon, methane, and nitrogen. Klemm (55) described transport phenomena in fused salts by the movements of components of unknown composition and determined experimentally the electric conductivity, diffusivity, viscosity, and transport numbers for a number of different salts.…”
