A learning experience on how to distil with a vacuum fractionating or short path still.

Master Principle: 

• Preserving delicate temperature sensitive aromatics and perform precision batch distillation.

Workshop contents:

• Introduction
  o Welcoming and Introduction of Participants
  o Workshop programme and structure
  o Scope of this workshop
  o Distilling safety - and especially for vacuum stills
• The anatomy of a vacuum still and the purpose of each component
• Temperature control (only possible in vacuum distillations)

  o Bath and boiler temperatures and control of boiling rate

  o Vapour temperatures 

  o Coolant temperatures

  o Purpose if using the agitator

• Different ways of specifying vacuum and pressure, absolute and relative vacuums

• Input variables and their impacts
  o Coolant water flow - main/reflux condenser (dephlegmator) (on fractionating stills)
  o Coolant water flow - spirit condenser
  o Cold-trap cooling importance and heat input control

• Practical distillation on a vacuum still (small experimental still and larger vacuum still)

  •  Participation
  •  Filling a still
  •  Setting up a vacuum still and coolant flows
  •  Starting heat and vacuum to bring to boil
  •  Adjustment when boiling starts
  •  Equalising/stabilizing your column
  •  The heads and fraction collecting and withdrawing
  •  Volume calculations for receivers
  •  Opening vacuum stills and shutting down procedures

• Conclusions, Q&A and discussions
