摘　　要：简介KDONAr-10000/20000/350型空分设备制氩系统流程以及精氩冷凝器堵塞现象,分析认为精氩冷凝器液氮侧压力控制过低,导致液氮节流降压后温度过低,使氩通道侧的氩冻结成固体而堵塞冷凝器。用来自下塔的中压氮气对精氩塔进行加温后,排除了故障,制氩系统投入正常运行。The technical proce, ss of argon-generating system of Model KDONAr-10000/20000/350 air separation plant and the phenomena of blocking of purified, argon condenser are briefed. The analysis shows that too low control pressure at liquefied nitrogen side of purified argon condenser results in too low temperature of liquefied nitrogen after throttling and pressure relief and thus the solid frozen argon at the argon passage side blocks the condenser. When the crude argon column is warmed with middle-pressure gaseous nitrogen from lower column, the trouble is eliminated and the argon-generating system runs normally again.
