It is. Fractional distillation. That is how many gases are generated, such as the ones you list.

yes,

Done by compressing and cooling air, converting the various gases into solids and liquids at very low temperatures.

sort of. distillation implies starting with a liquid and using differential vapor pressure to segregate by composition. So, there is an initial condensation stage that has to be performed on air before distillation can be used. That initial condensation can be used as a first step, a gross separation, but I am not sure it would be "distillation". this is more a word game, parsing of meaning and terminology, than a conceptual issue. Gases can be (and are) purified from air by taking advantage of the different physical properties of the gases.

Yes. Of course we're talking about distilling liquid air. Which means really really really low temperatures. But in any case, as we raise the temperature of the liquid air, the most volatile gases will boil off first...followed by the least. And each gas has it's own evaporation point; so we can use that fact to separate the gases and then recool them separately as the condensate.

Distillation operates based upon vapour liquid equilibrium. CO2 solidifies at around -55 Deg C, Nirogen, Oxygen liquifies around -165 deg C to -172 Deg C. Argon around -182 Deg C or less (pl. check) In commercial processes, atmospheric air is compressed and cooled and liquid is distilled in various column to get pure Nitrogne, Oxygen and Argon.First column will produce liquid Nitrogen, second column will produce liquid Oxygen and third column will produce liquid Argon.For detail please visit Linde Air liquifaction process on web.

... Yes, yes, yes - these gases are produced on a commercial scale by the fractional distillation of liquefied air. The local producer calls itself Liquid Air Products. When you get a good response, please consider giving a best answer. This is the only reward we get.

Not CO2 - it's a solid at those temperatures.
