Abstract

The invention discloses a method for optimizing the horizontal arrangement distance of a hazardous chemical substance gas detector. According to the method, aiming at a target chemical engineering device, various factors including meteorological conditions, surrounding environments, device leakage risks, historical accident cases, medium types, process parameters and the like are comprehensively considered, FLACS software is used for simulating various leakage scenes, and the detector horizontal arrangement distance capable of coping with the various leakage scenes is obtained through analysis. The credibility of a set accident scene is improved, the influence of geographical area factors on hazardous chemical substance gas monitoring can be reflected more accurately, and the temperature,pressure and components of gas leaked from different accident positions of the same device can be analyzed. Besides, the method considers various accident scenes of the same set of device, and integrates analysis results, so that the arrangement position of the detector can cope with all possible accidents on the premise of ensuring timeliness.

Description

technical field [0001] The invention belongs to the field of chemical safety engineering accident simulation and emergency rescue, in particular to the field of research on the arrangement of toxic and combustible gas detectors in chemical plant areas, and in particular to a method for optimizing the horizontal arrangement distance of gas detectors for hazardous chemicals. Background technique [0002] In the process of petroleum refining, high-concentration hazardous chemical gases are distributed in many major processing devices, which also brings a greater risk of poisoning, fire and explosion, and seriously endangers the lives of employees in the plant area. [0003] Whether the hazardous chemical gas detector is effective, detects the hazardous chemical gas with excessive concentration in the air in time, and sends out an alarm at the first time, so that petrochemical enterprises can evacuate the employees in the accident risk area as soon as possible, which is an effect...
