Problems solved by technology

Although this method is straightforward, it requires extremely high column packing and temperature control, and the separation efficiency and product purity are not ideal.
[0004] The above two methods can only realize the separation of a single krypton or argon gas, the process is relatively complicated, and the efficiency is not high, which has greatly restricted the application

Embodiment

[0083] see figure 1 , figure 1 For the implementation of this disclosure, it is proposed to disclose a system for efficiently separating and extracting inert gas from a small amount of ambient gas (such as air, groundwater, and dissolved gas in ice cores, etc.), including: moisture removal device 102, low-temperature fractionation device 110, sponge titanium chemical adsorption Device 120, gas chromatographic separation device 103, inert gas collection device 130 and vacuum device 101, wherein:

[0084] The vacuum device 101 evacuates the whole device, and the ambient gas sample (its main components are nitrogen, oxygen, methane, etc.) is passed into the moisture removal device 102 to remove moisture and carbon dioxide therein.

[0085] At the temperature of liquid nitrogen, the ambient gas sample is sent into the activated carbon gas storage pipe 1101 in the cryogenic fractionation device 110, and under the control of the gas mass flowmeter 1102, the fractionated gas and fra...

Abstract

The invention discloses a system for separating and extracting an inert gas from an environmental gas. The system comprises a dehydrating device, a low-temperature fractionation device, a sponge titanium chemical adsorption device, a gas phase chromatographic separation device, an inert gas collection device and a vacuum device. The invention also relates to a method for separating and extracting the inert gas from the environmental gas. The method comprises the steps of dehydration, low temperature fractionation, sponge titanium chemical adsorption, gas phase chromatographic separation and inert gas collection. The system and method are used for synchronously separating and extracting microlitre-scale krypton and 100-milliliter-scale argon.

Description

technical field [0001] The present disclosure relates to the technical field of gas sample separation and inert gas extraction, in particular to a system and method for efficiently separating and extracting a trace amount of inert gas from a small amount of ambient gas. Background technique [0002] The system and method for efficiently separating and extracting inert gases from a small amount of ambient gases (such as air, groundwater, and dissolved gases in ice cores, etc.) (Argon and Krypton) technology. Argon and krypton samples extracted by this method can be used in applications such as isotope and tracer analysis of environmental samples, such as radioisotope 39 Ar and 81 Kr, 85 Kr dating, etc. Specifically: for ambient gas samples (the main components of which are nitrogen, oxygen, methane, etc.), water and carbon dioxide are first removed, and then argon and krypton are separated by low-temperature fractionation, and then chemical sponge titanium is used at high...
