摘要:

在天然气行业防爆安全是企业的头等大事,在液化天然气(LNG)接收站工程设计中必须采取相应的措施。探讨了LNG接收站爆炸危险环境特点及危害以及释放源的确定,总结了危险区域划分方法,阐述了LNG接收站常用防爆措施,如建筑物的防爆设计、通风防爆设计、防爆电气设备的选用等,总结了国内LNG接收站工程防爆设计的特点,提出的建议对后续工程建设有借鉴作用。

Abstract:

Explosion-proof security is the top priority of the enterprise in the gas industry, terminal corresponding measures must be taken in engineering design in the liquefied natural gas (LNG) receiving terminal.This paper discusses environment characteristics and harms of the LNG receiving terminal explosion, as well as the determination of release source, summarizes the risk zoning dividing method and expounds commonly used explosion-proof measures of the LNG receiving station, such as the explosion-proof design of the structure, ventilation design, the selection of explosion-proof electrical equipment, etc., then concludes the explosion-proof design characteristics of domestic LNG receiving terminal engineering, and proposes the reference suggestions to the subsequent project construction.
