As an important protective layer of petroleum refinery installations,gas detectors can greatly improve the detection efficiency and reduce the loss if they are placed in a reasonable position.From the perspective of minimizing leakage risks,a quantitative optimization method of gas detectors placement was proposed.Several external factors of leakage diffusion process were quantified to calculate the scenarios occurrence probability,leakage consequence and risks.According to the failure mode and redundancy s...
