Why does water in the feed oil have a significant impact on the catalyst, while water in the recycled hydrogen has no such effect? ? The water in the circulating hydrogen is saturated water! ! The saturated water in the circulating hydrogen has no effect on the catalyst. Why? Is it because the water content in the raw material is high, causing large fluctuations in the vaporization pressure at the furnace, while the circulating hydrogen has almost no effect?

Do not delete the management instructions; I made a typing mistake earlier – neither the crude oil nor the recycled hydrogen should contain water.
Neither reciprocating nor centrifugal cycle hydrogen compressors can handle water; a large amount of water present constitutes a minor production accident in our case. There is a liquid removal tank at the inlet of the cyclic hydrogen compressor, which generally enables timely removal of liquid~~~
It has an impact as well, right? When water reacts with hydrogen sulfide to form hydrosulfuric acid, it corrodes both the equipment and pipelines!
Analysis of circulating hydrogen is required for each shift; let the data speak for itself – there is no water in it
It’s impossible to have no water; what the author is referring to here is the saturated water in the recycled hydrogen
The water content in circulating hydrogen is extremely low; generally, the dew point is used to indicate the amount of water present in it. Under normal conditions, no free water is formed in circulating hydrogen – any water present in the feedstock is in the form of free water, and everyone knows what effects that has.
