From the distribution of argon in the upper tower, it can be seen that part of the argon enrichment zone is in the distillation section and part is in the extraction section. The gas phase argon concentration in the rich argon region of the general distillation section is higher than that in the rich argon region of the distillation section, and the entire rich argon region of the distillation section contains three components: oxygen, nitrogen, and argon. However, the lower part of the rich argon region of the distillation section only contains two components: oxygen and argon. Therefore, the argon fraction extraction port should be located in the lower rich argon region.
Kaifeng DEAR Air Separation Industrial Co., Ltd. has signed a supply contract with Jiangsu Gaoyou Kangbo New Materials Co., Ltd. for a set of high-purity nitrogen air separation equipment for an annual production line of 10000 tons of high-purity polycrystalline silicon. The goal of this project is to use a high-purity nitrogen production system to produce nitrogen gas that meets the needs of high-purity polycrystalline silicon production
