Abstract


In order to improve the accuracy of the risk analysis of the hydrogen fluoride industrial production process, the HAZOP and LOAP methods were combined to conduct a semi-quantitative risk analysis of the rotary reactor in the hydrogen fluoride production unit to study the danger during the reaction. Firstly, HAZOP is used to analyze the possible consequences of the six deviations and propose corresponding safety measures. One hazardous scenarios is selected from the HAZOP analysis and LOPA analysis is performed. The LOPA calculation is used to compare the quantitative values with the risk tolerance values. By taking security measures to reduce the risk of dangerous scenarios that exceed the risk tolerance to an acceptable level. The results show that HAZOP-LOPA analysis can accurately identify potential safety hazards and improve the safety management level of enterprises.
