| Abstract: | The operation status of a 28000m3/h air separation unit with internal compression process after the occurrence of blockage at high pressure plate-fin heat exchanger is introduced.The cause of blockage accident is analyzed,and the negative effect on the stable operation,due to the leakage at the inter-stage cooler in the air compressor,is eliminated by heating the high pressure heat exchanger and adding a portable dew point analyzer. |
