Abstract

In a number of high tech and related equipment the stable isotopes of neon 20Ne and 22Ne find applications. To obtain them from natural neon are invited to establish installation with a cascade of rectification columns. The basic theoretical concepts are provides. The mechanism of neon separation into isotope components by distillation method is considered. It is calculated a number of transfer units in the upper and lower section of the column with various loads. The experimental characteristics of packed rectification columns are presented and examples of the construction of cascade schemes are given. The necessity of formation the initial steps of the cascade on the basis in parallel included rectification apparatus is proved. It is reported about record results for the enriching 21Ne, as well as obtaining 20Ne and 22Ne with isotopic concentration of more than 99,999%.
