摘要
LNG厂站的管线及设备安装结束、经过高速气流吹扫后,LNG储罐内存有微正压的空气,需用氮气将此空气排出(简称排空)。对LNG储罐的排空时间进行了计算,并比较了LNG储罐组串联和并联两种排空方法的排空时间及氮气用量。
There is some tiny positive pressure air in LNG tanks after pipeline and equipments in LNG station are installed and purged with high-speed air flow. The air in LNG tanks should be evacuated with nitrogen （called evacuation for short）. The evacuation time of LNG tanks is calculated, and the evacuation time and the nitrogen use level of the two evacuation methods of series arrangement and parallel connection of LNG tank groups are compared.
