Instructions for the calculation of distillation conditions

Surface diagram for (a) diesel fuel and (b) special diesel fuel 

the onset of decomposition is shown by a swelling out of the surface at high temperatures (320°C or more)  

various distillations may be compared rapidly by superimposing corresponding (transparent) diagrams. 

As a further iUnstration of this form of graphical representation Fig. 119 gives the diagrams for a diesel fuel (a) and a special diesel fuel (b). 

The plan of work indicated in Table 4 will be illustrated by means of an example showing the methods of calculation employed.
