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...
