本文详尽地分析了空分设备的制氩系统的氧氮氩三组分精馏及氧氩两组分和氮氩两组分的精馏与相平衡,讨论了氩组分在上塔的分布及氩馏分在上塔抽口位置的设定,分析了一般空分设备流程的的制氩系统原理及注意事项,同时对制氩系统的具体操作进行了详尽地阐述,希望能促进空气分离设备在制氩系统方面的发展。 This article detailed analysis of the air separation plant argon argon system oxygen and nitrogen three components of the distillation and oxygen and argon two components and nitrogen and argon two components of the distillation and phase equilibrium, discussed the distribution of argon components in the tower And the setting of the argon fraction in the port of the upper tower. The principles and precautions of the argon-making system in the process of the general air separation plant are analyzed. The specific operation of the argon-making system is also elaborated in the hope of promoting the air separation plant In the argon system development.
