I would like to ask: what is the current capacity of domestic manufacturers for PSA hydrogen purification?

What parameter are you asking about? Is it a flow rate or a gas parameter?

Our company uses hydrogen as a raw material for CO, at a rate of 15%, and is able to keep the CO level below 3 PPM.

Carbon monoxide and carbon dioxide levels are below 20PPM; we also use Shanghai Huaxi Technology

When a hydrogen-containing mixture is purified using the PSA method, and the impurities in the feed gas are mainly CO, CO2, N2, alkanes, etc., it is generally possible to keep CO+CO2 below 10 PPM, or CO below 5 PPM, resulting in a hydrogen purity of 99.995%–99.999%. The control of CO levels is the key factor here.
