The water content issue in aviation fuel hydrogenation units
Thread Content
Aircraft fuel hydrogenation generally requires that it be free of water, yet water separation tanks are installed, and water is removed on a regular basis. So, does the hydroprocessing unit for aviation kerosene in production actually contain water? Seeking expert advice for a solution
I have to handle it myself; doesn’t anyone know?
Keep trying; come on, is it really possible that no one can answer this question?
In my humble opinion, the reason no one answers is that the question is too simple. If it can contain water, then there’s no need for liquid removal; this is how quality is ensured. Generally, it also contains relatively little moisture, so cutting it once after a long period of time is sufficient. Or I don’t know what you want to ask

I’ve heard some people say that no water is produced during the entire process of jet fuel hydrogenation, and I’m puzzled – if there’s no water, then why is a separation tank needed? That’s why I ask this question. Moreover, a technician from a factory I know said that their water cutting pipelines are connected to those used for kerosene; it’s not clear whether jet fuel can be separated into water, and even if the process is carried out for an extended period of time, it’s uncertain whether water will be produced. So I think this issue isn’t simple; many people might not be aware of it
Water is drained regularly; of course, there will be water left. The raw materials or the processing process contain trace amounts of water, I guess
My question is the same as before; I hope to get an answer. Thank you
The responses weren’t uploaded even after a few attempts. . . What are your raw materials? One thing that’s hard to guarantee is the absence of oxygen; with oxygen-containing hydrogenation, water may be produced. That’s how I think about it. Also, is it possible for the raw materials to contain water due to fluctuations? Looking forward to experts as well
Reply to 8# apooly1002: The feed buffer tank is covered with fuel gas, so no air can enter; therefore, no oxygen can get in from the outside
It should have come off everywhere near the coalescer
Water may come from the raw materials, or from the distillation process; it can also be present as a result of stripping. Generally, aviation fuel is passed through dehydrators or coagulators to remove water. Water content in aviation fuel can lead to silver corrosion and copper corrosion, as well as issues with the freezing point not meeting specifications
