加油站在线监控模块在油气回收设施长效管理中的应用

Application of On-line Monitoring Module in Long-term Management of Vapor Recovery

以上海市为例,分析了加油站油气回收设施的运行现状,以及存在的内部管理制度落实不到位、治理设施维保难落实等问题,并在此基础上提出了加油站在线监控模块的设计思路。对加油站的跟踪测试表明,应用汽油枪气液比在线监控数据,有助于及时判定故障和报修,降低油气回收设备的维护成本;应用油罐压力在线监控数据,可以有效反映卸油时的油气泄漏情况,便于对卸油全过程实施监控。

Taking Shanghai as an example,this paper analyzed the current operation status of vapor recovery system in gas station and the problems of failing to carry out inner management system and facility maintenance,presented the idea of how to design the on-line monitoring module.Results from tracking monitoring showed that on-line data of vapor-liquid ratio could be used for timely fault judgment,and cutting the maintenance cost.On-line data of vapor space pressure could be used for supervising oil or gas leak in the whole process of oil unloading.
