Analysis and treatment of pressure deviation in upper and lower columns of a 40000m~3/h air separation unit |

| Abstract: | A case of pressure deviation in upper and lower columns of a 40000m~3/h air separation unit is introduced. Our analysis shows that the phenomenon is mainly caused by excessively high liquid level in nitrogen side of main cold heat exchanger, which occupies part of heat exchanging space. The malfunction was eliminated after liquid nitrogen was exhausted and corresponding adjustment was carried out. |
