| Abstract: | Every component in C2 fraction hydro- genation tail gas was qualitatively and quantitatively analyzed by back flushing technology with a 7 col- umn combined running - double detector - multi- channel switched multidimensional gas chromato- graph. The results showed that the method estab- lished in this test had higher accuracy and preci-sion. The relative standard deviations nents ranged from 0.07% to 1.98% tests, and the recoveries of standard 99% to 103%. of 14 eompo- for 6 parallel addition from |
