Title: Distillation process and apparatus
Inventor: BLITZ JOSEPH GERRIT
IPC: B01D3/14
Filed: 1959-02-02
Abstract: <PICT:0932391/III/1> Non-volatile impurities in the bottoms fraction withdrawn from a fractional distillation column 13 are separated from the volatile components by evaporating the bottoms liquid in an evaporator 22, part of the vapour being fed back into the bottom of the column by line 24 where it provides heat for effecting the fractionation; the remainder of the vapour is condensed in a condenser 27, and the condensate is collected in receiver 30.  The less volatile components of the mixture are discharged through outlet 23a.  The proportion of bottom fraction vapour returned to the column by line 24 is controlled by regulating the rate at which condensation of the remaining vapour occurs in condenser 27, such control being advantageous when fractionating under fluctuating pressure, as, e.g. under vacuum.  Preferably the condenser 27 has part of its cooling surface immersed in condensate to a depth controlled by the condenser's outlet valve (not indicated) so that if the condensate level should tend to rise, a smaller cooling surface is exposed thus causing less of the bottom fraction to be condensed thereon.  In Example 1 a mixture comprising 25% of pentylaldehyde and 70% of pentyl alcohol was separated under atmospheric pressure, and in Example 2 a mixture consisting chiefly of C12, C14, C16 and C18\t fatty acids was separated under reduced pressure from associated glycerides.
