Abstract
Hydrogen fluoride (HF) is a typical dangerous gas in the fluorine chemical industry. Its leakage is one of the most common types of accidents in this industry, and it poses a serious threat to personnel safety and health, environmental sanitation, and social stability. In this paper, the process and consequences of an HF leakage accident in a fluorine chemical plant were simulated by using computational fluid dynamics (CFD) simulation software, and hazardous areas (lethal area, severe injury area, light injury area, and maximum allowable concentration area) of HF diffusion were determined according to the HF concentration corresponding to the degree of personal injury. Moreover, the effects of wind speed and height on hazardous areas were analyzed. The research results of this paper provide model support for similar enterprises to predict the consequences of harmful gas leakage accidents, and give suggestions on emergency evacuation and rescue work, which have practical application significance.
Highlights
Hazardous gas leakage and diffusion accidents have a wide range and can cause large losses [1,2,3,4]
Compared with the wind speed of 1 m/s, Hydrogen fluoride (HF) no longer accumulates at the bottom of buildings near the leak hole, but spreads far away
After fully considering the injury effect of HF on the human body, the affected area was divided into lethal area, severe injury area, light injury area, and MAC area
Summary
Hazardous gas leakage and diffusion accidents have a wide range and can cause large losses [1,2,3,4]. Hydrogen fluoride (HF) is a typical dangerous gas in the fluorine chemical industry. There have been many HF leakage accidents. In 2009, in the United States, thousands of people were evacuated urgently because of a hydrofluoric acid leakage in a fluorine chemical plant. In 2012, a HF leakage accident occurred in Gumi, South Korea, which caused necrosis of vegetation within 1 km and toxic gas staying for more than ten days [5]. In 2018, three deaths in China occurred due to HF poisoning
