AI Technical Summary

Technical Problem

Existing carbon molecular sieve gradient adsorption methods suffer from mass transfer imbalances due to changes in carbon molecular sieve pore size after prolonged use and accumulation of trace impurities in the sample gas, which affects Kr enrichment.

Method used

By controlling the cooling device to cool the primary adsorption column, the instantaneous flow rate and krypton concentration are obtained. The flow rate change rate and adsorption efficiency are analyzed, and the adsorption parameters are adjusted to overcome the influence of pore size changes and competing gases, so as to ensure the efficient enrichment of Kr by carbon molecular sieve.

Benefits of technology

By varying the pore size of the carbon molecular sieve, efficient enrichment of Kr was achieved, overcoming the influence of mass transfer resistance and competing gases, and ensuring the efficient adsorption of Kr by the carbon molecular sieve.
