is it possible to separate oxygen from air?
in other words, getting pure oxygen from air

If it were easy, do you think they wouldn't already have thought about it?Quadruple Bypass said:damn, that sounds like its going to take a long time. i was seeing if it was possible to get a car to suck in pure oxygen instead of air, but it would have to make a lot of oxygen in a short period of time
thanks
Just a disclaimer first: saying "pure" is relative. There are always contaminants in your product, regardless of the method used. Even distillation is only going to give 99.99xx percent purity.Quadruple Bypass said:is it possible to separate oxygen from air?

It won't. The fuel/air mixture is precisely controlled to provide exactly the amount of oxygen necessary for efficient combustion.Q_Goest said:And third, it don't believe it [will] improve efficiency. I'm not absolutely sure about the efficiency part, but I know there have been discussions in the ME forum about this. Might want to do a search in the engineering forums, there was a discussion not too long ago.

Don't understand what you mean; if you can introduce more oxygen in the combustion chamber, you can also introduce more combustible, so you have more power.russ_watters said:It won't.

If that's the goal, a turbocharger does a great job of doing exactly that.lightarrow said:Don't understand what you mean; if you can introduce more oxygen in the combustion chamber, you can also introduce more combustible, so you have more power.
Yes....and power would increase dramatically...
Why? You've changed nothing about the chemistry of the combustion....and pollution would decrease dramatically.
Have you ever heard of using compressed N2O injected in the combustion chamber to increase power? O2 it's not used just because the bottle/cylinder contains less of it so it finishes soon.russ_watters said:If that's the goal, a turbocharger does a great job of doing exactly that.Don't understand what you mean; if you can introduce more oxygen in the combustion chamber, you can also introduce more combustible, so you have more power.
You don't change the chemistry but you change the physics. You have much less HC with an higher percent of oxygen, because the combustion is more efficient (O2 is less diluted by N2); furthermore, if N2 percent is very low, you would have much less NOx.Why?

Oxygen can be separated from air through a process called fractional distillation. This involves cooling the air, compressing it, and then passing it through a series of chambers that separate the different components based on their boiling points. Oxygen has a lower boiling point than nitrogen, so it can be collected as a gas while the nitrogen remains in liquid form.
Oxygen is necessary for many industrial processes, such as combustion and oxidation reactions. It is also essential for human and animal respiration. Separating oxygen from air allows us to obtain pure oxygen for these purposes.
In addition to fractional distillation, there are other methods for separating oxygen from air. These include membrane separation, which uses a semipermeable membrane to separate the gases, and pressure swing adsorption, which uses a material that can selectively adsorb oxygen molecules.
Overall, separating oxygen from air is considered to be an environmentally friendly process. The main energy source used in fractional distillation is electricity, which can be produced using renewable sources. Additionally, separating oxygen from air reduces the amount of pollutants released into the atmosphere.
Separated oxygen has a wide range of applications. It is used in the production of steel, chemicals, and fuels. It is also used in medical settings for oxygen therapy and in scuba diving tanks. Additionally, separated oxygen is used in the aerospace industry for rocket propulsion.
