Purge Streams & Inert Buildup

Inside this lesson
  • Explain inert buildup in recycle loops and why it prevents steady state without a purge
  • Write a steady-state inert balance around the recycle loop
  • Relate purge flow to recycle-loop composition and impurity entering in the fresh feed
  • Size a purge stream to satisfy an inert-balance requirement
