A process flow diagram - pfd - (or system flow diagram - sfd) shows the relationships between the major components in the system. Pfd also tabulate process design values for the components in different operating modes, typical minimum, normal and maximum. A pfd does not show minor components, piping systems, piping ratings and designations. A process flow diagram includes: process piping major equipment symbols, names and identification numbers control, valves and valves that affect operation of the system interconnection with other systems major bypass and recirculation lines system ratings and operational values as minimum, normal and maximum flow, temperature and pressure
