| Abstract: | One physical explosion accident occurring in the main heat exchanger of a small scale oxygen and nitrogen plant after condition switch during temporary shutdown process is introduced.On analyzing the cause, it is found that the remaining liquid air in the enclosed space of main condenser's condensing side evaporates by absorbing heat,which leads to the overpressure explosion. |
