PROCESS FLOW DIAGRAMS

---

Process Flow Diagrams (PFD) should not be confused with P&ID's. PFD’s are considered the forerunner of Piping and Instrumentation Diagram. They are also known as a System Flow Diagram (SFD) or Flow Diagram.

A Process Flow Diagram should only  include:

• Process Piping, major equipment symbols, names and identification numbers, control valves and main valves that affect operation of the system, interconnection with other systems, major bypass and re-circulation lines, and may include a table showing each streams process data.

A Process Flow Diagram should not include:

• Minor components, minor piping systems, piping ratings and designations, isolation and shut off valves, control schemes, relief and safety valves.

• When planning a grass roots project
• When developing or understanding overview of the process.
• When a process needs to be studied for improvement.
• To communicate to others general chemistry and flow of the process.
• When better communication is needed between people involved with the same process.
• To document a process.
• When all streams need to be clearly communicated in that process.
