Case Study #4 P&ID of a Whisky Brewery

Let’s draw a P&ID for a basic unit:

  • We’ll make a P&ID for a Distillation Unit, which, as you may know, is more complex:
    • Distillation (Tray Column)
    • Feed/Recycle Streams
    • Reboiler
    • Condenser
    • Temperature, Pressure, Level Control

Strategy:

  • Understand the process, and what we need to draw (and not)
  • Get started with Margin and limits
  • Unit & Equipment:
    • Trayed Column
    • Secondary units (reboiler, condenser, vessels, pumps, etc.)
    • Streams (product, byproduct, utilities, etc.)
  • Instrumentation (ignore for now)
    • Instrument
    • Control 
  • Review
