Embodiment Construction

[0130] The present specification provides methods and systems that can utilize spectral emissions that occur due to electrical discharges within a gas to monitor and / or manage a gas downstream of a purification unit that includes adsorption of the gas onto an adsorbent and / or monitor the concentration of impurities in the gas upstream of the purification unit. The present specification also provides methods and systems for extending the useful life of adsorbents.

[0131] general definition

[0132] It will be readily understood that the gas of interest may include noble gases. In some implementations, the gas to be purified can include argon, helium, neon, krypton, xenon, or combinations thereof. It should be understood, however, that the methods and systems described herein can be used to purify any gas that contains gaseous impurities.

[0133] Those skilled in the art will readily appreciate that adsorption includes the reversible and / or irreversible adsorption of a g...

Abstract

A method for extending the useful life of an adsorbent for purifying a gas by adsorbing impurities is provided. The method involves generating an electrical discharge within the gas to obtain a spectral emission representative of the concentration of the impurity. The method also includes monitoring the concentration of the impurity based on the spectral emission. The method also includes reducing the concentration of the impurity by converting at least a portion of the impurity to a secondary impurity that has a greater affinity for the adsorbent than the impurity. The method also includes comparing the concentration of the impurity to the concentration of the contamination and managing the adsorption of the gas onto the sorbent based on the comparison.

Description

technical field [0001] The field relates generally to gas purification by surface adsorption, and more particularly to methods and systems for managing gas purification using spectral emission. Background technique [0002] Removal of impurities from a gas can be performed by adsorbing the impurities on the active surface of a catalytic adsorbent such as a non-evaporable gettering alloy. For example, it is known to purify noble gases such as argon, helium, neon, krypton or xenon by passing such noble gases over a heated zirconium-based adsorbent, such as a zirconium alloy. The zirconium alloy may be provided in powder or pellet form and contained in an insulated stainless steel vessel which may be heated. Zirconium alloys are used as gettering alloys for the removal of impurities such as H from gases 2 O, N 2 、CH 4 , CO, CO 2 、H 2 and NMHC (non-methane hydrocarbons), etc. [0003] As with most adsorbents, the getter alloy does not retain its adsorptive activity indefi...
