The Mystery of Vibration on the Synthesis Tower Platform

This post was last edited by beipiaoye on 2009-8-2 21:20. There is an iron platform on the water cooler of our synthesis equipment, connected to the vent pipeline, which makes it convenient for us to access the safety valve or drain valve of the water cooler. Every time the hydrogen content entering the tower is too high or too low, this platform vibrates violently. I asked many people, and they all said it seems to be related to gas density. But nothing can be explained clearly. Does anyone know? I’m completely puzzled; what on earth is going on?
Both too high and too low hydrogen-to-nitrogen ratios can lead to poor synthesis reaction performance, an increase in system pressure, higher compression work for the circulator, and easier vibration in the system pipes. Regarding the issue of density. Mainly, nitrogen has a much higher density than hydrogen, the intermolecular forces are also much stronger, and the compression work required is greater as well. Therefore, a high nitrogen content causes greater damage to the cycle gas compressor, and the current of the cycle machine increases at this time.
Changes in the hydrogen-to-nitrogen ratio cause the conditions for ammonia synthesis to be deviated from, which deteriorates the ammonia synthesis reaction and reduces the synthesis rate. This leads to an increase in system pressure, higher compression work by the compressor, increased motor current, and ultimately an increase in pipeline flow, making the system pipes prone to vibration. At the same time, such phenomena are more likely to occur in environments with high nitrogen content. As mentioned on the second floor, the main reason is that nitrogen has a much higher density than hydrogen, resulting in stronger intermolecular forces and thus greater compression work. Therefore, a high nitrogen content causes greater damage to the cycle gas compressor, and the current of the cycle machine increases at this time.
Thank you all for sharing your valuable advice; I am truly very grateful.
