Abstract

Crude helium neon mixture is a valuable product, which is taken from the air separation unit larger installations. Purification of a mixture of nitrogen is carried outusing equipment located near the air separation plant. This allows the content in a mixture of neon and helium to bring up to 94 %. For purification of crude Ne-He-mixture of excess nitrogen usually use low-pressure reflux. The technology of purification Ne-He-mixtures of nitrogen in the high-pressure reflux. Calculated and experimental research of high pressure reflux showed that it characterized by lower costs of electricity, recycled water and liquid nitrogen, it has a in 4 times less mass than the low-pressure reflux.
