Why did a phenomenon similar to overheating occur suddenly at the reactor outlet during diesel hydrogenation? First, the pressure decreased; later, once the pressure was adjusted, the temperature rose suddenly. The amount of hydrogen remained unchanged and the furnace temperature was normal.
Could you talk about your adjustment process?
With changes in reactor pressure that are adjusted to normal levels, the amount of hydrogen must change as well. 1. Check the circulating hydrogen flow rate to see if there are any significant fluctuations ； 2. Check whether there are significant changes in the properties of the raw materials and the feed rate, such as the rectification ratio.
