Faq of Nitrogen making process of air separation plant

What are the restrictions on the amount of expanded air entering the tower?

The amount of expansion air entering the upper column increases, and the reflux ratio of the rectification section decreases correspondingly. In order to achieve the required purity of the nitrogen product, more trays need to be provided. When the reflux ratio is reduced to the point that countless trays need to be set to make the nitrogen purity reach the required value, the reflux ratio at this time is called the minimum reflux ratio. The amount of expansion air entering the tower is first lim...

Why did small oxygen generator extract part of the distillation gas when producing high purity nitrogen?

The air contains 0.932% argon. When 99.6% oxygen is to be produced from the upper tower, 1.05% argon must be contained in the nitrogen discharge. From the perspective of separation process, the distillation section of the upper tower (below the liquid inlet) is basically oxygen-argon separation, while in the distillation section (above the liquid inlet) then it is basically nitrogen-oxygen (argon) separation. The boiling point of argon and oxygen is relatively close (the boiling point of oxygen is-182.97 ℃ at 0.1013MPa, and the boiling point of argon is-185.7 ℃), so it is relatively difficult to separate. In the distillation section, such a situation often occurs. In the process of nitrogen-oxygen separation, the oxygen component is not separated clean, and the argon component basically escapes together with the oxygen component in the nitrogen discharge, reduce the purity of nitrogen. If it is required to produce high purity nitrogen, the oxygen component should be completely separ...
