利用Excel97电子表格软件的规划求解方法 ,计算下塔纯液氮中的氩含量 ,并指出了液氮中氩含量随下塔回流比、塔板数等的变化规律 ,最后简单讨论了液氮中氩含量与空分设备氩提取率的关系。图 5表 2参 2。
The calculation of argon content in the lower column of pure liquid nitrogen was calculated by the method of Excel 97 spreadsheet software. The variation of argon content with the reflux ratio of the lower column and the number of trays was pointed out. Finally, Relationship between argon content and argon extraction rate in air separation plant. Figure 5 Table 2 Reference 2.
