—— Operation

Feed liquid is admitted into still under high vacuum, immediately spread into a very thin film and forced quickly down the evaporation surface. Heated walls and high vacuum drive the more volatile components (distillate) to the external condenser as the less volatile components (residue) continue down the cylinder. The resulting fractions, thus separated, exit through individual discharge outlets. Depending on application, the desired product is either the distillate or the residue fraction. Small amounts of condensable low MW compounds collect in cold trap upstream of vacuum system. For high solvent loads, an optional external condenser may be installed immediately downstream of the still.

In vacuum operations, the air ingress is very much possible, whereas in pressure operations the vapour emissions are likely to occur. The distillation process is inherently hazardous with flammables and the presence of huge volume of flammables in reboilers, in column internals and adjacent piping pose huge explosion hazards in these distillation units.

Concentration gradient between top and bottom of the column has a bearing on safety. Concentration of impurities in the column can lead to hazards.
