well. when Clark Kent came to earth in his space ship made by his father(i assume) traces of his exploding planet followed. so when it fell people picked it up from the ground therefore you extract it from the earth not the air ..h hahahahha
Krypton is found in air
You use a cryogenics compressor--a machine that repeatedly compresses, cools and depressurizes air. As the air gets colder and colder, gases will drop out of it. At -191C you will get some krypton--the concentration in air is only one part per million, so you won't get much. (This is why krypton is very expensive.)
Krypton is found in the air on Earth to the extent of about 1ppm
Krypton is isolated from liquified air by a process called fractional distillation.
neon was discovered by a Scottish chemist, William Ramsay, and a English chemist Morris travers, a little after their discovery of krypton. Neon and krypton were discovered through the study of liquified air. Neon was discovered when ramsay chilled a sample of The atmosphere until it was a liquid, then he warmed it, and captured the gasses as it boiled

Krypton is an element obtained from liquefied air. In 1898, it was discovered by William Ramsay and Morris Travers as they were studying liquefied air. Small amounts of krypton also is found in the earth's atmosphere. It is a gas with the atomic number of 36.
Liquefy it by cooling and reducing pressure and then do fractional distillation.
From the fractional distillation of the liquid air.
neon
It was found the year to be 1898, it was discovered in the air. I searched krypton on Wikipedia.org, "The World's Encyclopedia" the had a complete article on it.
