In recent years, the frequency of chlorine leakage or explosion accidents is going on rising, for the sake of solving this problem, the chlorine leakage accident of Jiangxi Lipin chemical plant is chosen as an example.

But because of the exist of undefined factors during the transport, the leakage accident happens easily and the malignant accident such as poisoning, fire, explosion etc can be initiated possibly during the transport.

Aimed at the present situation of gas pipeline in Pingdingshan City,the reasons causing accidents are found by analyzing the leakage accidents of gas pipeline.

The oil leak accidents induced by different causes occurred in more than 30 years in the Northeast oil pipeline networks have been analyzed.

This paper analyzes the causes of one buried oil delivery pipeline leak accident.

Atmospheric risk forecasting model for simulation of leaking accident of poisonous gas pollutant was used to calculate the maximum ground concentration and its location of pollutant as well as whether the pollutant will affect the resident areas,hospitals and schools and other sensitive spots located in the accident district.

Hazardous chemicals leakage accident and its disposition;

Based on analysis of main factors causing failure of petrochemical equipment, a leakage prediction model of typical petrochemical equipment is worked out with the help of LEAK software designed by DNV.

Progress of accidental release source and mechanism models;
