Discussion on sampling locations for methane analysis of circulating gas for ammonia synthesis
Thread Content
As for the sampling location for the methane analysis of the circulating gas of synthetic ammonia, our factory uses gas analysis before entering the tower, but is it better to take the circulating gas after the ammonia is separated by the synthesis reaction and before supplementary gas is added, or is it better to use the supplementary gas to mix and then enter the tower for gas analysis to guide production? Which reference is helpful for adjusting the hydrogen-nitrogen ratio of gas production? (The difference between the two is 3~4% methane)
Can you explain it with a picture?
Of course, the position should be after the ammonia is separated and before entering the circulation machine. The ammonia synthesis reaction is controlled by adjusting the gas composition entering the tower.
