Analysis of the crude argon column blocked by nitrogen and measures to be taken

Yan Shou peng (Hangzhou Deling Whole Cryogenic Equipment Engineering Co , Ltd , 1 702 San Tang Apartment House,Hangzhou 310004,Zhejiang Province)  
The three conditions concerning the crude argon column blocked by nitrogen and corresponding measures to be taken are described in brief.The main factors affecting the operating conditions of distillation in a crude argon column are analyzed(i e the nitrogen content in argon fraction,the thermal loading of the condenser/reboiler in a crude argon column and the structure).In addition,the causes leading to the fluctuation of the nitrogen content in argon fraction and the measures to be taken to adjust it are discussed.
