摘要
对青岛某炼厂的挥发性有机物进行采样和分析,对比了2种不同材质气袋的储存稳定性,同时在控制光照和是否加入保护气的条件下进行采样分析。得出结论,针对炼厂固定源挥发性有机物,聚酯铝(PEA)气袋的平均回收率(79.6%±4.0%)明显优于泰德拉(PVF)气袋(72.9%±4.0%)。且光照和保护气的加入会对实验结果产生一定程度的影响。
Samples of volatile organic compounds were collected from a refinery in Qingdao. The storage stability of two kinds of airbags with different materials was compared. At the same time, the samples were analyzed under the conditions of the control of light and whether the protective gas was added. It was concluded that the average recovery of PEA(polyester aluminum) air bags(79.6%±4.0%) was significantly better than that of PVF(polyvinyl fluoride) air bags(72.9%±4.0%) for stationary volatile organic compounds in the refinery. And light and protective gas will have a certain degree of impact on the experimental results.
