Environmental Diffusion Analysis and Consequence Prediction of Liquefied Ammonia Leakage Accident
Shuxia Li, Liping Liu, Tijun Fan and Huan Cao

Abstract:
The demand for the industry chemicals, which serve as the main material and product of heavy industries, has seen a dramatic increase with the development of industrialization and transportation. Meanwhile, dangerous chemicals accidents such as liquefied ammonia leakage occasionally happen due to operational uncertainty, which will do great harm to people and animals because of their hazardous characteristics. In this study, the overall diffusion process of the hypothesized liquefied ammonia leaking accident is firstly analyzed. Then, source density and flash strength are calculated which proves that the diffusion of liquefied ammonia leakage transforms from heavy gas to non-heavy gas in specified time. Furthermore, influence range of gas cloud, concentration change of some fixed point and flammable and explosive region are predicted based on Aloha. Through the consequence prediction, factors in terms of distance from leakage source, wind speed, stability of environment and ground roughness are compared, according to which it can be inferred that the cloud concentration is split into two centers in initial state and cloud tailing with wind exists.
