What is vacuum distillation?

Vacuum distillation is a process by which volatile compounds are separated from the liquid mixture by using the tendency of such compounds to evaporate from a mixture at increased speed at lower atmospheric pressures, often without increased temperature. By closing the mixture in the distillation tank and reducing pressure, volatile compounds are induced that evaporate from the mixture. The steam is then captured and condensed back into the liquid. Vacuum distillation can be carried out on a small scale in the laboratory or industrial scale, as is the case in oil refineries. It is a pressure at which a particular compound easily evaporates from the liquid solution. Vacuum distillation uses this feature to separate individual compounds from mixtures, especially when refining petrol products. The liquid to be separated is located in a closed container with a pressure control system. Using the known steam pressures of specific elements of the mixture, the pressure is reduced and sometimes the temperature increases until the desired compound starts evaporate or boil from the shiftsi.

After the conversion of the required compound, it is collected, cooled and returned to standard atmospheric pressure to condense it. It can even be under pressure on higher than standard atmospheric pressure, if it is usually gas, such as fuel as a propane, convert it to liquid. By submitting a mixture, such as raw raw, this way can be separated and improved by many different components of the mixture. Raw oil may contain hundreds of hydrocarbons, and in many cases vacuum distillation is the only way to separate them from one more easily and efficiently.

compounds that have a high boiling point or whose vapors are heavier than air in one standard atmosphere of pressure are particularly suitable for separation by vacuum distillation, especially if they are dissolved in water or in a mixture containing water. Vacuum distillation also allows compounds to distill at lower temperatures than possible. This is the use oftangible for compounds that are changed or distributed by heating.

The

vacuum distillation device can be relatively simple, such as devices that are sometimes used in laboratories or extremely complex, such as large towers found in oil refiner. The vacuum distillation tower in the oil refinery can be several stories and can be able to separate dozens of hydrocarbon compounds. Small laboratory settings can be very simple and occupy more than a table top.
