Assessment of the Design Method

The overall design obtained wasverysuccessful. With theavailability of comprehensive chemical equilibria data it was possible to develop an accurate mathematical model to aid the design calculations. The sieve tray and mechanical column design were both straightforward and appeared to be efficient. 

The accuracy of this model appears to be very good. Comparison of the results with actual industrial column applications (see Ref. A2) suggests the model is indeed highly accurate. The limiting component in the model is the accuracy of the equilibria data, but as the majority of these empirical correlations are still used after more than 40 years their reliability should be almost guaranteed. 

The shell and head design was in accordance with the design
