Interfacial Gradients in Ethanol Dehydrogenation Experiments

Example 3.3-1 Interfacial Gradients in Ethanol Dehydrogenation Experiments 

In a calculation of this pe it is frequoitly encountered that physicochemical data concerning the reacting components are lacking. Excellent estimates may then be obtained through the use of general correlations for the transport properties, however. In this example only correlations that can be found in Reid and Sherwood [25] ate used. They also explain the background of these correlations. 

Estimation of the Partial Pressure Drop over the Film Estimation of Viscosities 

CH3CHO Use the method of corresponding states, since the potential parameters are not available. 

Since the hydrogen content cannot be neglected, Wilke s method may yield too high a value for the viscosity of the mixture. Therefore, the viscosity is computed as
