Embodiment Construction

[0048] The present invention will be further described below in combination with embodiments.

[0049] The present invention comprehensively considers many uncertain factors of dangerous gas leakage that may occur in oil refinery units, and realizes real-time quantitative characterization of oil refinery risk risks based on the risk triplet theory and leakage scene sets, and uses this as a risk quantification index for layout decision-making. Then, taking the minimization of the decision-making risk as the optimization goal, taking the number of detection alarm devices as the constraint condition, and taking the selection of the alarm device layout candidate point as the binary decision variable, the objective function and constraint function of the optimization model are defined, and a reliable model is established. Minimal Risk P-Median Problems Including Unavailability and Voting Effects (MRPMP-UV) for decision-making risk minimization of gender and voting logic. Specific s...

Abstract

The invention discloses an oil refining device gas detection alarm apparatus site selection arrangement method capable of considering multiple factors. The real-time risk quantitative characterization of an oil refining device is realized on the basis of a risk triple theory and a leakage scene set and is used as an arrangement decision risk quantitative index. Then, arrangement decision risk minimum is taken as an optimization objective, the amount of detection alarm apparatuses is taken as a constraint condition, whether an alarm apparatus arrangement alternative point is selected or not is taken as a binary decision variable to define a target function and a constraint function of an optimization model, and a MRPMP-UV (Minimal Risk P-median Problems Including Unavailability and Voting Affects) is esablished. The method has the following beneficial effects that the unavailability and invalidation situations of the alarm apparatus are fully considered when scheme optimization is carried out, the successful detection probability of the detection alarm apparatus is brought into a consideration range, and therefore, an optimization result is accurate.

Description

technical field [0001] The invention relates to a site selection and arrangement method for a gas detection and alarm instrument of an oil refinery considering multiple factors. Background technique [0002] At present, in the field of petroleum refining and chemical industry, relevant technical standards (such as SH3063-1999 "Code for Design of Detection and Alarm of Combustible Gas and Toxic Gas in Petrochemical Enterprises", GB50493-2009 "Design Specification for Detection and Alarm of Combustible Gas and Toxic Gas in Petrochemical Industry", SY6503-2000 "Code for Combustible Gas Detection and Alarm Use" and SY-6503-2008 "Safety Technical Specifications for Combustible Gas Detection and Alarm Systems in Petroleum and Natural Gas Engineering", etc.) as the main basis for the layout of traditional gas detection and alarm devices, only combustible gas and toxic gas detectors Provisions have been made on the principle of setting the detector, the distance between the detector...
