Abstract: After a study based on chemical analysis and ammonia synthesis process, it induces that neon and helium are the possible inert gases at the inlet and outlet of the ammonia synthesis column in Hulun Buir Jinxin Chemical Co., Ltd. The paper also studies how to analyze and test the gas chromatography method applied to determine the two inert gases, and gets the accurate content of the two components, which can be used as an important reference for the adjustment of the ammonia synthesis process.
