Abstract: This paper makes safety risk analysis on the original design of ethylene oxide feed and transportation system inside and outside the boundary zone respectively. The ring tube arrangement of ethylene oxide outside the boundary zone is optimized to avoid the dead zone of ethylene oxide caused by intermittent feed and the safety of the plant operation is improved. The paper carries out theoretical calculation of the heat transfer of the ethylene oxide feed system with steam tracing within the boundary zone. The thermal expansion caused by temperature rise and the heating time are calculated quantitatively when the cut-off valve is shut down. The feed system within the boundary zone is optimized to avoid the risk of ethylene oxide leakage due to the overpressure caused by excessive heating and pipeline rupture in case of emergency.
