Improved Technology for Obtaining Enriched Neon-Helium Mixtures

Chemical and Petroleum Engineering Aims and scope

A novel technology for the production of high concentration neon-helium mixtures on different air separation units (including units without fraction separators) is presented. It is proposed to complete the ASU with pressure swing adsorption (PSA) devices for obtaining a neon-helium mixture. The PSA unit enriches the neon-helium mixture due to the energy of compressed gases taken from the ASU condenser-evaporator. The calculations of the PSA technology was performed using the wave approach. The implementation of this approach takes unsteady transient mass transfer processes into account both in the layers of the adsorbent and inside of the grains. It is shown that the proposed technique makes it possible to obtain an enriched neon-helium mixture with a total concentration of neon and helium to 90 and with a recovery ratio of 40–50 %.
