Abstract

Rare gases are highly needed products obtained using high technology. In this regard, much attention is paid to improving the equipment used in these technologies. Methods for cooling phase separators used for condensation enrichment of a neon-helium mixture are considered. The most common option involves an open-loop refrigeration cycle based on liquid nitrogen. However, the boiling point of nitrogen at atmospheric pressure does not ensure achieving the required concentrations of neon and helium. Alternative methods for cooling the separators to lower the temperature to the value of Т 68 are proposed. As a result, additional enrichment of the mixture with the target products at the output from the phase separators is obtained.
