| Abstract |
A procedure is the potential risk analysis of toxic effects of underground industrial pipelines in Yilan County is taken as an example. The research objective is to analyze the potential risks of toxic effects of three underground industrial pipelines, paraxylene and m-xylene. Depth will affect the area of toxic effects and the amount of leakage. In the pipeline circulation area, add high-density population, sensitive receptors, and primary and secondary wind direction analysis maps. You can know the extent of toxic effects and the influence of seasonal wind directions. For relevant units to prepare emergency materials and manpower in advance to assist emergency response and personnel evacuation. The data source provides pipeline data for underground industrial pipeline operators in Yilan County. The research method uses the entire section of the pipeline as the possible accident point, sets the worst scenario and the main and secondary wind directions in each season. The size of the hole is based on the Kaohsiung gas explosion. The propylene pipeline is broken, and population risk considerations are added. The analysis of ALOHA diffusion simulation software is used to integrate the GIS geographic information system calculation map to analyze the risk potential of toxic effects. The conclusion of the study was that the results of the hazard analysis of the toxic disaster were analyzed. The buried depth is inversely proportional to the influence range of the ring zone. The deeper the buried depth of the pipeline, the smaller the influence range of the ring zone. Depending on the depth of the buried pipe, the affected range is different. The most economical and effective depth is 4 meters. And the leakage of underground pipelines and pipe pressure will maintain a certain rate, so the danger potential of poison disasters will move, and the high-risk areas will move to the downwind. Therefore, the high population density of the downwind in the southeast wind will affect the distribution in more villages. |
