| Abstract: | The process and damage of a burst accident in the return valve of liquid oxygen pump in air separation unit with internal compression process are introduced.The preliminary analysis shows that the accident cause to chemical explosion might be high-pressure oxygen leakage,which results from the upper valve body crack during pressurization process due to the valve's manufacturing defects.The measures to prevent the burning and exploding of the return valve of liquid oxygen pump are also presented. |
