How to control the oxygen content in nitrogen generators
Is PSA still cryogenic? For PSA, adjust the adsorption time and ensure thorough regeneration, etc. For cryogenic processes, pay attention to material balance and heat balance; once stabilization is achieved, controlling the outlet gas flow rate is usually sufficient~~
Xiaobai asks: Why is it necessary to control the oxygen content? Isn’t the lower, the better?
Controlling the adsorption time and the regeneration backflow time – generally, manufacturers set these values in advance based on the required purity level, so it is not easy to control them. The flow rate at the outlet should not exceed the value specified by the equipment; otherwise, the purity level is likely to exceed the acceptable limit
To control the purity, you can contact the manufacturer and ask their after-sales staff to make adjustments in order to maintain a certain level of purity
