Abstract

Cryogenic adsorption, referred to as Cryogenic Molecular Sieve Bed (CMSB), is one of the technologies capable of purifying and recovering helium-3 produced in tritium storage systems. In typical adsorption process using temperature swing adsorption, the regeneration step to remove impurities adsorbed on the adsorption bed is performed by heating and purging with either a portion of the product gas or an inert gas. To enhance the recovery efficiency and purity of helium-3, vacuum regeneration can be employed as an alternative to gas purging. This study evaluated the applicability of the vacuum regeneration for CMSB in the helium-3 recovery system. The adsorption performance of the two regeneration methods, gas purging and vacuum regeneration, was compared experimentally. Vacuum regeneration was confirmed to be reliable and demonstrated comparable performance to the gas purging method.

低温分子筛床真空再生的验证

低温吸附，简称低温分子筛床（CMSB），是一种能够净化和回收氚储存系统中产生的氦-3的技术。在采用变温吸附的典型吸附过程中，通过用部分产物气体或惰性气体加热和吹扫来进行去除吸附床上杂质的再生步骤。为了提高氦-3的回收效率和纯度，可以采用真空再生法替代气体吹扫法。本研究评价了真空再生技术在氦-3回收系统中的适用性。对气体吹扫和真空再生两种再生方式的吸附性能进行了实验比较。真空再生被证实是可靠的，并且表现出与气体净化方法相当的性能。
