PFD

What is a Process Flow Diagram - PFD. A short definition. 

A Process Flow Diagram - PFD, is a schematic illustration of the system.

PFD's show the relationships between the major components in the system. PFD's also tabulate process design values for the components in different operating modes, typical minimum, normal and maximum. PFD's do not show minor components, piping systems, piping ratings and designations.

A PFD should include: 

Process Piping 
Major equipment symbols, names and identification numbers 
Control, valves and valves that affect operation of the system 
Interconnection with other systems 
System ratings and operational values as minimum, normal and maximum flow, temperature and pressure 
Composition of fluids 


Input Data
