摘要
因空分装置循环氮气压缩机第二段压缩后水冷器换热管泄漏,造成精馏系统冰堵事故,通过堵管焊接及增设排淋阀等方法进行处理,杜绝了此类事故再次发生。
A leakage accident happened in the internal tube of heat exchanger in secondary compression after water cooler in circulating nitrogen compressor in ASU, causing ice block accident in rectification system. By plugging and welding the tube, adding drain valves, such accident never happened again.
