| Abstract: | An analysis method for determining the components of ethylene cracking gas by gas chromatography is introduced. Using multidimensional gas chromatography, collocating with four valve and seven column, three channel parallel and three detector, all of the components in ethylene cracking gas are rapidly separated and determined by valve switching and column backflush technology. The results show that the analysis method has advantages of fast speed, high efficient, simple operation and accurate result. |
