Rectification. Difference between the rectification and distillation
1. Rectification
{ It’s a obtaining alcohol 96%2. Difference between the rectification and distillation
• Differencebetween
the
rectification
and
distillation
The resulting alcohol is possible in two main
ways by distillation (simple distillation) and
rectification.
For example:
The fermented raw materials or finished
wine is poured into a cube and is heated to
vaporization temperature. The evolved
vapors enter the cooler and under the
influence of the temperature difference is
converted into liquid. As it turns out raw
alcohol strength of 40-50 degrees. This
product is not sufficiently separated from the
impurities, it needs to further purification
and additional deinking.
Often, instead of insisting and extracts the
distillate is distilled again - this increases its
degree. If the output to get alcohol very high
purity and strength, resorted to the second
method - the process of rectification.

The high purification of crude alcohol occurs inthe distillation columns consisting of a side-bar,
reflux-cooler and the nozzle.
It allocates heated feed steam which moves in the
side-bar and interacts with a reflux liquid,
covering the pipe wall. Part of the vapor
deposited in a reflux condenses and drops in
alcohol, the remainder is returned to the drawer
side.

Process of the rectification shows theexpansion of the liquid in the heavy and light
fractions, as a result of which the feed is the
most cleaned of contaminants, suspensions,
fusel oils.

Rectified spirit is of particular strength. Itcontains up to 96% alcohol, it is widely used
in the technical, medical purposes, for
preparing herbal balms and bitters.
As you can see, the fundamental difference of
distillation from the alcohol rectification, is
not only in the techniques of distillation, but
also in a final product.
