I would like to ask everyone: how to convert the recovery rate and filling ratio in PSA nitrogen production, and how to choose an adsorption tower?
Nitrogen generator manufacturers provide data on the nitrogen production rate (amount of nitrogen produced per ton of molecular sieve), as well as the air-to-nitrogen ratio. For example, when German-made molecular sieves are used, at a pressure of 5N, the air-to-nitrogen ratio is 7.1 (with a yield of ~17.8%), and the nitrogen production rate is 55 Nm3/T.H~~
You can consult manufacturers of nitrogen generators or molecular sieves. Additionally, dual towers are generally used for the adsorption towers; as for the radius-to-height ratio of these towers, it depends on parameters such as gas flow rate and loading capacity~~
Each manufacturer has its own method of calculation
Do you mean that this air-to-nitrogen ratio varies among different manufacturers? Is the difference significant? Is there any formula I can use as a reference? Thank you
Is this calculation formula universal? Do you know where it is described? Thank you
Each manufacturer has its own algorithms; non-professionals can only make an approximate estimate based on parameters such as the oxygen-to-nitrogen ratio and bulk density of the molecular sieve, and the error is likely to be minimal
