Can an air separation unit extract only nitrogen, with a purity of 99.5% v? What is the maximum extraction rate possible?

Advice from experts, please. . 、、Thank you
Sure. In the traditional low-temperature nitrogen production process, the nitrogen extraction rate is around 50-60%. There are also many improved designs, allowing for very high nitrogen extraction levels.
The type mentioned by the original poster is quite simple; we call it a single-stage column. It’s similar to the lower section of a distillation tower, and it’s possible to extract only oxygen as well
Yes, there is just one tower. It is used in mines, glass, and rolled products. A relatively simple form of gas separation.
