Distillation in a sentence

Applications of distillation The application of distillation can roughly be divided in four groups: laboratory scale, industrial distillation, distillation of herbs for perfumery and medicinals ( herbal distillate ), and food processing.

The main difference between laboratory scale distillation and industrial distillation is that laboratory scale distillation is often performed batch-wise, whereas industrial distillation often occurs continuously.

Extractive distillation Extractive distillation is similar to azeotropic distillation, except in this case the entrainer is less volatile than any of the azeotrope's constituents.

A simple vacuum distillation system as exemplified above can be used, whereby the vacuum is replaced with an inert gas after the distillation is complete.

By additional fractional distillation, the liquid oxygen may be enriched to contain 0.1–0.2% of a krypton/xenon mixture, which is extracted either by absorption onto silica gel or by distillation.

Continuous distillation differs from batch distillation in the respect that concentrations should not change over time.

Distillation of mixtures If two solvents can form a positive azeotrope, then distillation of any mixture of those constituents will result in the distillate being closer in composition to the azeotrope than the starting mixture.

Distillation was historically performed using an alembic or pot still until the continuous still was invented which made the distillation process much more economically efficient.

Laboratory scale distillation Typical laboratory distillation unit Laboratory scale distillations are almost exclusively run as batch distillations.

Reflux refers to the portion of the condensed overhead liquid product from a distillation or fractionation tower that is returned to the upper part of the tower as shown in the schematic diagram of a typical, large-scale industrial distillation tower.

Section of an industrial distillation tower showing detail of trays with bubble caps Design and operation of a distillation tower depends on the feed and desired products.

Short path distillation is a distillation technique that involves the distillate travelling a short distance, often only a few centimeters, and is normally done at reduced pressure.

Simple distillation In simple distillation, the vapor is immediately channeled into a condenser.

The beverage was usually low-proof, and the distillation process had to be repeated several times (a three-stage distillation process was common).

The unit process of evaporation may also be called "distillation": *In rotary evaporation a vacuum distillation apparatus is used to remove bulk solvents from a sample.

This test method extends to the atmospheric distillation of petroleum products using a laboratory batch distillation unit to quantitatively determine the boiling range characteristics of petroleum products.

Unlike distillation, freeze distillation concentrates poisonous congeners rather than removing them; As a result, many countries prohibit such applejack as a health measure.

While vacuum distillation of ethanol is not presently economical, pressure-swing distillation is a topic of current research.

Another process is distillation, in which compounds are separated based on the temperature at which they boil.

First-time restaurant owners, they offer something special here, a distillation of the flavors, techniques, and seasonings that open the door to the cooking of this part of the world.
