Analysis of Influencing Factors of Failure of Chloroethylene Oxychlorination Unit Based on Fault Tree Method
In order to solve the problem of frequent unplanned shutdown,fault tree analysis was used to analyze the risk factors of oxychlorination unit in a vi-nyl chloride plant,and the abnormal fault tree of oxy-chlorination unit system was constructed.The main failure factors of oxychlorination unit were deter-mined,such as catalyst run loss and cyclone separa-tor fault blockage,showing good results after meas-ures were taken and applied.
