| Abstract: | The outlet oxygen pressure from the column of a 10000m^3/h air separation unit was found lower than usual level, after two shutdowns due to lightning strike and electric network failure. The pressure drop is attributed to the blockage in oxygen channel caused by the intruding rainwater at the cold end of main heat exchanger. The malfunction was successfully cleared off through intense wanning up. |
