摘　　要：针对LNG/L-CNG加气站中设备选型与实际需求不匹配的问题,在确定拟建加气站日加气能力、建站位置、占地面积、加气时间集中与否、停运影响大小、LNG存储时间等基本条件的基础上,根据国家相关标准要求和行业经验,给出加气站主要设备的选型方法,包括LNG储罐、LNG泵撬、加液机、L-CNG泵撬、L-CNG气化撬、程序控制盘、储气系统、CNG加气机、卸车撬及控制系统等。提出的方法能够在满足加气站日加气量和高峰时段加气要求的基础上,节省投资和运维成本,提高加气站的运行效率及系统可靠性。To solve the problem that the selected equipment could not match the actual demand in LNG/L-CNG t＇rlling stations, after determining the basic conditions including daily filling volumes, station locations, station areas, concentrated gas filling hours or not, station outage＇s impact and LNG storage time, based on the national standards and industrial experiences, proper selection methods were proposed for main equipment, such as LNG tanks, LNG pumps, LNG dispensers, L-CNG pumps, L-CNG gasifiers, program boards, gas storage facilities, CNG dispensers, unloading device, control systems and other equipment. The methods could not only meet the requirements of daily gas filling and gas filling in peak hours, but also could reduce investments and operation and maintenance costs while improving the efficiency and reliability of filling stations.
