摘　　要：KDON-21000/22000型空分设备的循环粗氩泵回流管路在实际运行过程中,会造成液氩浪费,而且可能影响制氩系统甚至整个空分系统的运行工况。对循环粗氩泵回流管路进行了优化改造,减少了冷量损失,提高了氩提取率,使设备运转经济性和安全性进一步提高。详细介绍优化改造方案以及取得的经济效益。During actual operation, the return pipeline of circulation crude argon pump of Model KDON-21000/ 22000 air separation plant would generate waste of liquefied argon and likely impacts the condition of the argon generation system and even the entire air separation system. The return pipeline of circulation crude argon pump is optically reformed, which decreases the loss of cooling capacity, increases argon extraction ratio, and further improves the economy and safety of the equipment. Here, the scheme of optimized reform and the realized benefits are detailed.
