Thermal conductivity carbon dioxide + ethane

Cg portion and then switching to the TCD for carbon dioxide, ethane, oxygen (if present), nitrogen, and methane, a complete analysis is shown in Figure 6.30. The signal was automatically switched to the thermal conductivity detector at 8 min.

The evaluation of the excess contribution to the thermal conductivity of carbon dioxide-ethane mixtures has been performed by a route parallel to that employed for the viscosity. Again, that route has been described in detail in Section 5.5.1.2 so that here it is merely recorded that for pure carbon dioxide and pure ethane the thermal conductivity has been taken from the work of Vesovic et al. (1990, 1994). All other quantities required for the calculation are the same as those employed for the zero-density thermal conductivity. In this context it should be noted that the Thome-Enskog equations employed for these calculations have, as their zero-density limit, the Hirschfelder-Eucken result in the form of equation (15.5). Figure 15.3 contains the pseudo-radial distribution functions for carbon dioxide and ethane determined... 

As was pointed out earlier, there are no published thermal conductivity data for the carbon dioxide-ethane system in which either the excess or the background contribution have been unequivocally identified. Consequently, no comparison with experiment is yet possible.

The absence of experimental data for the thermal conductivity of the mixtures of carbon dioxide and ethane precludes a comparison with the predictions at this intermediate stage in the discussion. 

Partition Column Run for Ethane and Heavier Hydrocarbons and Carbon Dioxide — This run is made using either helium or hydrogen as the carrier gas if other than a thermal conductivity detector is used, select a suitable carrier gas for that detector. Select a sample size in accordance with 8.1. Enter the sample, and backflush heavy components when appropriate. Obtain a corresponding response on the reference standard.
