摘要
以1 750 m3液化天然气(LNG)子母罐的安全保护系统为例,探讨四级安全保障系统(自力式降压调节阀—BOG压力控制阀—安全阀—泄放阀和呼吸阀)的设置方式和工艺过程,从经济上分析了设置BOG压力控制阀的必要性。
Taking the safety protection system of 1 750 m^3 liquefied natural gas （LNG） cluster tanks for example, the setting mode and process flow of the fourlevel safety protection system composed of self-operated depressurization regulating valve, BOG pressure control valve, relief valve, discharge valve and breather valve are described. The necessity for setting BOG pressure control valve is analyzed economically.
