The height-to-diameter ratio of typical PSA nitrogen generators is within a reasonable range; what is this range approximately? Are there any formulas or methods? Based on a unit produced by our factory a few days ago, the height-to-diameter ratio is around 1.3, and this approach seems to work fine. What impact does the height-to-diameter ratio have on nitrogen generators? Thank you to the expert for clarifying this.
Generally, a height-to-diameter ratio of 2:1 is fine; it’s also okay if the four towers have a ratio of 1:1. 【\"Gas Purification\"】This book provides detailed explanations
The answer above is correct; generally, our height-to-diameter ratio is ≥2, and this ratio mainly affects the angular velocity of the empty tower

This seems hard to understand – with such a low height-to-diameter ratio, the gas flow velocity is too high, making it very easy for a tunneling effect to occur, and it becomes difficult to achieve the desired purity level. How can this height-to-diameter ratio be adjusted to eliminate the tunneling effect and enable the attainment of the designed purity?
Height-to-diameter ratio of 1.3? ~~I remember that the height-to-diameter ratio of PSA for air separation is generally 4 to 7~~
For nitrogen generators, the height-to-diameter ratio increases as the purity rises, and it decreases when the purity is low.
Who can send a picture so I can get an idea?
