Discussion on Safety Distance for LNG Project
摘要
Abstract
The calculation of safety distance is an important link in the construction of LNG project. We should fully consider the public social security of the surrounding people and property and the safety of natural ecological environment in the calculation of safety distance. In this paper, the typical accident cases caused by insufficient safety distance in the domestic and international LNG installations are analyzed, and relevant domestic safety distance regulations, standards and requirements are compared. Finally, the existing methods for determining the safety distance in China are summarized. This paper proposes that the consequences of accidents should be chosen as the main basis, and the mathematical model as the analysis method to perform study on diffusion of steam cloud, fire, explosion and other conditions. From the perspective of quantitative risk, the availability for safety measures to reduce the risk are determined, and suggestions for setting safety distance are also proposed. Through analysis, it is believed that the unit that has a great influence on the whole system should be selected, and the safety distance should be determined by quantitative analysis method based on accident consequences. The results can provide technical service and support for the risk assessment of safety distance in LNG project.关键词
