on use for neon, and that is in electric and fluorescent lights to produce a bright orange-red glow.Neon is produced industrially by distillation of liquefied air. The most volatile part of the liquid air is comprised of nitrogen, neon, and helium. The nitrogen is removed by condensation under increased pressure, and lowered temperature. Then, the nitrogen is adsorbed by highly cooled charcoal. Neon is separated from helium by selective adsorption on activated charcoal at low temperatures. Extracting neon from air is lengthy, and produces only 1 pound of neon for every 88,000 pounds of air that is processed....
