In Chemical Engineering there is a thin line between EVAPORATION and DISTILLATION. The principle is the same, that is , taking advantage of difference in volatility
DISTILLATION
It is a Liquid-Liquid separation
The more volatile component is the product which is then cooed and collected as distillate. It usually involve more equipment than evaporation. It is a Multi-component separation
EVAPORATION
Solid-Liquid separation (thus its major industrial application) and the product is the less or non-volatile component
Liquid-Liquid separation (with very limited economic industrial application) and the product is the more volatile component
It is a two component separation
Vacuum evaporation is a thermal evaporation technique that consists in heating the materials until evaporation.
The difference among other thermal evaporation techniques is that low pressures are used due to avoid reaction between the vapor and atmosphere. At low pressures, the mean free path of vapor atoms is the same order as the vacuum chamber dimensions, that way particles travel in straight lines from the evaporation source towards the substrate.
Now a days vacuum evaporation is considered one of the most efficient technologies for industrial wastewater treatment.
Under normal atmospheric pressure, water boils at 100 degrees Celsius (or 212 degrees Fahrenheit). In a vacuum, water boils at any temperature above freezing; it has no liquid phase. So if you want to distill something without having to heat it, vacuum makes that possible.
The Difference of the atmospheric Distillation to Vacuum Distillation is can be determine in the use of the Boiling Points.

Alaqua Inc provides best distillation equipment in all over the USA. This distillation equipment that can be used for various purposes such as solvent distillation where vacuum systems can be attached to the distillation machine to distill solvent while under a vacuum. While utilizing vacuum distillation equipment, the boiling point of the solvent is lowered, decreasing the temperature necessary for distillation of the solvent. Distillation: Equipment and Processes Distillation equipment is the equipment used for the separation of crude oil into more fractions to be used for various purposes such as transport, heating, and power generation. Its uses also include the separation of salt from the sea water, the air is also distilled by industries to separate its components such as oxygen, nitrogen, and argon. Specifications of Distillation Equipment A distillation process, which comprises the stages below, is used to recycle solvents: A batch or continuous distillation vessel processes waste solvent solution. By using conductive thermal transfer, a heated jacket heats the waste solvent. Vacuum can be applied to the vessel, lowering the solventβs boiling temperature. The waste solvent transforms from a liquid to a vapor when it reaches its boiling point. Clean solvent vapor travels via a condenser with a condensing and sub-cooling portion. The solvent returns to a liquid state in the condenser, where it is cooled to room temperature. The impurities do not transit through a vapor phase and remain in the drain port to be released.
The major steps include:Desalting - removing salt, water, dirt and other impuritiesCrude and vacuum distillation - start separating the crude oil into separate productsConversion - modifying the composition of the productsBlending - putting together measure amounts of products to make something that does a specific job
because there is is a pressure difference between the inside of the bottle and the outside. the pressure is lower in the bottle the egg gets sucked in. when the oxygen is burned there is less matter in the bottle then at first and that results in less pressure[vacuum]
Usually by using a vacuum pump or a water aspirator, the boiling point of the liquid is reduced.

oils and perfumes.
When pressure is reduced the boiling point will also reduce
No, the efficiency lies in the suction and brush types.
A pressure gauge measures blow, a vacuum gauges measures suck

It appears that the 4870MZ is the replacement for the 4870GZ vacuum cleaner, which will eventually be going out of stock.
An absolute vacuum is purely theoretical, and is an utter absence of matter. An implosion is essentially a violent inward collapse.

In a vacuum, water boils at a much lower temperature, so you can boil away the water without having to cook something in the process. In addition, all chemical compounds boil at lower temperatures in a vacuum, than they do under normal air pressure, so various forms of distillation can be done in a vacuum, not just removal of water.
A vacuum cleaner and a vacuum flask are both very simple to use. Both are household items that are simple to operate and require very few instructions.
I'm not sure what you're really looking for in an answer to this but the short and sweet is this.Distilled water is water that has been distilled either by a purifier or a laboratory to not have any trace amounts of ions or compounds in solution. Distilled water is favored in laboratory analysis because it doesn't contain any reactants that can interfere with results.Fractional Distillation is an experimental technique to separate liquids from each other based on the difference of their boiling points. There are 3 main types of distillation techniques; simple, fractional, and vacuum. Simple and fractional are similar and have almost the same apparatus. Fractional adds an extra column so that it can more precisely separate two or more compounds that have a closer boiling point. Vacuum is for materials that would decompose at higher temperatures so pressure is added to decrease the temperature required to boil. Since boiling is dependent on vapor pressure this allows vacuum filtration to separate out compounds.
