| Abstract: | The valve for controlling argon flux from vapor space of liquid argon tank to pure argon column caused an excess gas nitrogen concentration participating the rectification in pure argon column, and then led to a nitrogen block in the column. The system normal working condition was recovered by reducing production output and carrying out corresponding operations. |
