I. With respect to the method of argon purification:

The first kind

Direct deoxygenation. It is to use active metal, catalyst and oxygen in argon to react, digest the oxygen in argon, so as to achieve the purpose of deoxidation, absorb the water in argon through molecular sieve, so that the water content of argon is less than 1ppm.

The second kind

Is the use of getter. At a certain temperature, the getter can absorb nitrogen, hydrogen, oxygen, carbon monoxide, carbon dioxide, methane and other gases after absorption treatment, the purity of argon can reach 6 nines, and the high-purity gas produced by this process is suitable for various process equipment and instruments.

The first method equipment investment is small, the second method equipment purification purity is high but the investment is relatively large.

II. Technical parameters of the argon gas purification system:

1, processing capacity: 1 ~ 5000 Nm3 / h (customized according to user needs)

2, raw gas requirements: liquid argon or better pipeline argon can be used

3, working pressure 0.1-1.6 MPa

4, purification efficiency of argon gas purification system: after purification, it meets and exceeds the 99.999 requirements of GB / T4842 - 2017

Input argon purity ≥ 99.99%

The output gas index is ≥ 99.999%, and the impurity content is as follows:

O 2≤0.5ppm；

H2O≤0.5ppm

CO+CO2≤0.1ppm；

Number of dust particles (≥ 0.01 um) 3 ~ 5 / L

III. Features of argon gas purification system:

(1) The purifier has the characteristics of good adsorption depth and large amount of impurity gas absorption, and the purity can reach 99.999% or more than 99.9999%;

2, the purifier adopts a special structure and charging method, the flow rate is reasonable, and the airflow distribution is uniform;

3, full BA grade or EP grade stainless steel polishing tube. Adopt imported ball valve. The re-pollution of the gas flowing through the pipeline is eliminated.

4, double structure, after the boot of a group of work, another group of regeneration, standby, and EA series automatic argon purification device work and regeneration are automatically carried out, it can be continuous gas supply, one can top two single use.

5, the company's production of EA series automatic argon purification device function explaination:

A, with fully automatic function, simple operation, open, stop just press two buttons, no need to twist any valve, these work are automatically carried out by the PLC program; It overcomes the gas impurity caused by manual and semi-automatic models due to human operation errors, so the purity quality of argon is also more stable.

The display device adopts high quality LCD touch screen, which can simulate and display the workflow status and various parameters in real time, and can modify the parameters at any time.   

C, can be equipped with on line analyzer according to customer requirements, real-time online monitoring of argon purity.

IV. Application fields of argon gas purification system:

This series of argon gas purification system is suitable for scientific research institutes, colleges and universities; Preparation of mixed gas and standard gas, ultra-pure gas analysis; High purity gas filling station; Production of high purity materials; Semiconductor manufacturing processes; Smelting of special steel or high purity aluminum; Hydrogen removal and purification of inert gas aluminum melt; Protective gases in the petrochemical industry; Purification of argon recovery;
