Definitions

  • the flash tower 5 shown in the drawing is provided with 4 product side withdrawal lines 20.
  • the remaining vapour if any is withdrawn over the top of the flash tower 5 via line 7 by the action of the steam ejector system 6.
  • the driving steam from the steam ejector system 6 is directly passed together with vapour, if any, from the flash tower 5 via line 21 into a second column 22, hereinafter called stripping tower, which is maintained at a higher sub-atmospheric pressure than the pressure in the flash tower 5.
  • the steam passed over the top of the stripping tower 22 is introduced into a plurality of condensers 30, one of which is shown in the drawing, for condensing the steam at substantially atmospheric pressure.
