Fractional Distillation
As air is a mixture of gases, it must first be liquefied.
This is done by lowering the temperature and increasing the pressure.
It is firstly compressed and CO2 and water vapour are removed.
The remaining air is then cooled to about 103 K. It is allowed expand suddenly which causes it to cool further so that it becomes liquefied.
The liquid air is allowed to heat up slowly in a fractionating column.
At 77 K, the liquid nitrogen boils off as a gas and is collected. Liquid oxygen boils at the higher temperature of 90 K.
The liquid oxygen is then stored in an insulated container.
There are several ways to do it, but the industrial way is to liquify the atmosphere in a very cold container. At certain points the higher liquification-point fractions are poured out and the operation continues until all the gas is liquified and separated. Nitrogen makes up most of what they get, so liquid nitrogen is very cheap. Oxygen comes out second. Argon third.
Nitrogen and oxygen are extracted from air by compressing and cooling to convert them to a liquid. Oxygen is the first of these two to liquefy Other gases such as argon and carbon dioxide are also extracted from air during this process. The temperatures at which the various gasses liquefy depends on the exact pressure and many vary quite a bit.
air is made into a liquid. (allow air too) boil or evaporate. Condense the vapors /or collect the vapors in order (of evaporation)
The technique is called fractional distillation. Air is cooled to a liquid and then allowed to boil. The various component gases boil at different temperatures allowing separation.
freeze it one will freeze before the other it gets cold relly quickerly
1. Distillation of liquefied air
2. Separation on molecular sieves
heat it slightly. The nitrogen will boil off before the oxygen and argon content of air.

How do you produce Synthetic glucose from air water light and oxygen?
you cant
Is the m50 mask is most effective in confined spaces where there is not enough oxygen in the air you breathe to support life?
No, the m50 mask is not the most effective in confined spaces where there is not enough oxygen in the air to breathe to support life.
How does spray foam work as insulation?
Spray foam works as insulation due to a chemical reaction that occurs when the spray foam is introduced to oxygen in the air. Inside the can, there is no oxygen and the can forms an air tight seal. The oxygen that reacts with the spray foam causes the foam to expand from five to ten times its size, thus filling all cracks and crevices.
How is sating on room air spelled Is it sating or satting?
It is satting on room air. I am not sure about the "satting" on room air. When a someone, physician etc, says the patient is "satting" they are referring to the oxygen saturation. To be correct, they should say "saturating" but they are shortening it to "sat-ing". In the medical transcription world, it is not transcribed unless specific instructions are given by the client...Otherwise, a sentence with "satting" would be transcribed as.... The patient was saturating at 99% on room air. OR The patient's oxygen saturation is 99% on room air. I have seen it given in the vital signs and written: O2 saturation 99% on room air. OR. Oxygen saturation 99% on room air. If this is for a report on a verbatim account--I would use "saturating", not "satting.
Why is it important to pump air through the aeration basin?
To keep oxygen in the water for the bacteria that "eat" wastes in the water to help purify it. If the oxygen level gets to low, the bacteria die, and the water in the basin doesn't get cleaned.
How is air separated into nitrogen and oxygen and carbon dioxide?
Air is separated in components by fractional distillation.
How do you chemically separate oxygen from air?
Oxygen can be separated from air through a process called cryogenic distillation. This method takes advantage of the differences in boiling points of the components in air, with oxygen having a lower boiling point than nitrogen. By subjecting air to extremely cold temperatures, oxygen can be liquefied and then separated from the other components.
Can oxygen be separated from materials found with it?
Yes, oxygen can be separated from materials it is found in through processes such as electrolysis, which uses an electric current to split water molecules into oxygen and hydrogen. Other methods like fractional distillation can also be used to separate oxygen from air.
Is air mostly oxygen and nitrogen a mixture or compound?
Air is mostly a mixture of gases, primarily nitrogen and oxygen. Nitrogen makes up about 78% of air, while oxygen makes up about 21%. These gases are not chemically bonded and can be separated from each other.
How argon is separated from air?
Argon is separated from air by a process called cryogenic distillation. Air is cooled to very low temperatures to liquefy and then slowly heated up. As different components of air have different boiling points, argon is separated from other gases based on its boiling point which is lower than that of nitrogen and oxygen.
What happens in the lungs air sacs sacs?
In the air sacs oxygen and other gases are stored and separated to be put into the blood stream.
What physical property of oxygen enables it to be separated from the other components of air?
The physical property of oxygen that enables it to be separated from the other components of air is its higher boiling point compared to nitrogen. This difference in boiling points allows for distillation or fractional distillation processes to separate oxygen from the air mixture.
How the nitrogen is separated from air. what is the needed temperature for that?
Nitrogen can be separated from air through a process called fractional distillation, where air is cooled to extremely low temperatures (-196°C) to turn it into a liquid. The different components of air, including nitrogen, oxygen, and other gases, can then be separated based on their boiling points, with nitrogen being collected as a gas as it evaporates first.
Why is air consider as a mixture while it cannot be separated physically?
Air is considered a mixture because it is composed of different gases such as nitrogen, oxygen, argon, and carbon dioxide. While these gases can't be physically separated, they retain their individual properties and proportions in the mixture. This is what makes air a mixture rather than a compound.
How pure is oxygen separated from air?
Typically, air is cooled to a liquid state, then the air is boiled and different components of air can be distilled out due to the fact that each one has a different boiling point. The process is known as Fractional Distillation. The oxygen produced by the process is typically > 99% pure.
How is oxygen obtained industrially?
Oxygen is obtained industrially through the process of fractional distillation of liquefied air. In this process, air is cooled and liquified, then it is separated into its components by distillation. Oxygen is separated from nitrogen and other gases due to their different boiling points, and then collected for industrial use.
How can a air homogeneous mixture be separated?
An air homogeneous mixture can be separated through fractional distillation, which takes advantage of the different boiling points of its components (mainly oxygen and nitrogen). By gradually heating and cooling the mixture, the components will vaporize at different temperatures and can be collected separately.
