加油站二次油气回收系统效率测试方法

The Method of Testing the Operating Efficiency of the Gasoline Station PhaseⅡVapor Recovery Syste

通过分析二次油气回收系统的油气逸散通道,利用气体流量计、压力表和温度计搭建效率测试工艺流程,将测得油气体积转化为标准状态下的体积。根据各测试点的质量排放因子得到二次油气回收系统的质量回收效率,为二次油气回收系统的整体评价方法提供了科学指导。

By analyzing the channel of vapor, the technical process for testing the operating efficiency of the Phase Ⅱ vapor recovery system has been built by using the gas flow meters, pressure gauges and ther- mometers, the measured volume of vapor has been converted to standard state. According to the mass e- mission factors for each test point, we can get the quality efficiency of the Phase Ⅱ vapor recovery sys- tem and provide the overall evaluation for the Phase Ⅱ vapor recovery system.
