1500/100 Y-type solution for small air separation plant in new material industry
The new material industry system of our country has been initially formed and the development situation is good. With the introduction of national strategic planning such as "The development plan of national strategic emerging industries in the 13th Five-Year Plan" and "The development plan of new material industry in the 13th Five-Year PlanThe new material industry system of DEAR air separation has been initially formed and the development situation is good. With the introduction of national strategic planning such as "The development plan of national strategic emerging industries in the 13th Five-Years Plan" and "The development plan of new material industry in the 13th Five-Years Plan", it has created a good policy environment for the development of new material industry.

to increase oxygen extraction rate.The advantages and disadvantages of nitrogen expansion are:1) The gas does not enter the upper column after nitrogen expansion, so it will not directly affect the distillation conditions of the upper column. Its superheat degree after expansion can be higher than that of air expansion, and the pressure after expansion can also be lower than that of air expansion. Therefore, the unit cooling capacity is greater than that of air expansion. Under certain condition...

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...
