What is the difference between a process flow diagram and a P&ID?

Generally, a Process Flow Diagram shows only the major equipment and doesn’t show details. PFDs are used for visitor information and new employee training. A Process and Instrument Drawing (P&ID) includes more details than a PFD. It includes major and minor flows, control loops and instrumentation.

How do you create a P&ID diagram?

Here are 8 steps to draw your own P&ID

  1. Step 1: Define the scope of the system.
  2. Step 2: Identify the inputs.
  3. Step 3: Identify the outputs.
  4. Step 4: List all the equipment in the process.
  5. Step 5: Define the relationship between components.
  6. Step 6: Piece together your flow.
  7. Step 7: Add detail.
  8. Step 8: Review the process.

What is the difference between BFD and PFD?

In a brief BFD represents entire process in a single sheet, where as in PFD you can find some detailed information like plant operating conditions, process flow. It uses symbols to represent the equipment. P&IDs provide detail information when compared to above two drawings.
