Abstract

The sole significant source of neon is atmospheric air (18 ppm by volume). Until recently, the use of neon was limited because of its very high cost, but with the advent of tonnage oxygen plants it has become feasible to consider the use of neon on a larger scale. Helium, which is present in air at a concentration of 5.3 ppm[1], may also be recovered during the same process but not at a cost which is competitive with helium from natural gas nor in quantities which are important.
