Each PFD will require many P&IDs to provide the necessary data. Figure 1.7 is a representative P&ID
for the distillation section of the benzene process shown in Figure 1.5. The P&ID presented in Figure 1.7
provides information on the piping, and this is included as part of the diagram. As an alternative, each
pipe can be numbered, and the specifics of every line can be provided in a separate table accompanying
this diagram. When possible, the physical size of the larger-sized unit operations is reflected by the size
of the symbol in the diagram.
