A risk-based methodology for optimum placement of flammable gas detectors within open process plants

Numerical investigation of flammable vapour cloud formation from pools of heated organic liquids

“…QRA typically uses many case scenarios combining consequence estimation with event frequencies ( Woodward, 1998 ). Besides, the flammable vapour cloud characteristics are valuable for determining the detection device distribution and arrangement, use of mitigation systems, and emergency response ( Rad et al, 2017 ; He et al, 2020 ; Shen et al, 2020 ; Liu et al, 2021 ).…”

Flexible alarming mechanism of a general GDS deployment for explosive accidents caused by gas leakage

“…Reasonable reduction of the sensor's detection threshold can effectively improve the detection rate of small leaks (Kelsey et al, 2002(Kelsey et al, , 2005. Amirhosein quantifies the risk by comprehensively considering the possibility of leakage scenarios, personnel hazards, property damage and ignition possibility to establish risk-based optimization function model and solve it by greedy algorithm (Rad et al, 2017).…”

A quantitative deployment scheme of hazardous gas detector

“…Most of the existing studies are based on equal probability scenes and ignore the probabilities of occurrence. Rad et al 13,14 proposed a deployment model based on risk and maximum weighted risk reduction, considering factors such as leakage probability and wind direction probability. Zhang et al 15,16 proposed and compared three SP models, namely the minimal detection time p-median (MDTP), the minimal leakage concentration p-median (MLCP), and the minimal individual risk p-median (MIRP), which are used for different optimization goals.…”
