Hydrogen stripping tower uses hydrogen stripping
Thread Content
The diesel hydrogenation stripping tower originally used 1.0MPa steam, but now it is planned to be changed to hydrogen stripping. Is there any refinery that has used it? Can I ask for advice on the hydrogen ratio?
I heard that there was a place in Shanghai that caught fire because of hydrogen stripping, which caused the naphtha to contain a lot of hydrogen! These are the results of the survey, you know!
Don’t be blamed for irresponsible nonsense! Because I only heard about it and couldn’t find any reports.
Many refineries in Shandong use it! Feasibility is still possible
It can be used, but after use, the water content of jet fuel does not change much.
How should I put it? If your 1.0Mpa steam pressure and temperature can be guaranteed, steam stripping is still better, and it is more practical from a cost perspective. I don’t know why you want to change to hydrogen.
Since downstream acid water stripping is limited, we also have the idea of changing to hydrogen stripping, which can reduce acid water and fundamentally solve the problem of acid water carrying oil impacting downstream. But what is the stripping effect? At the same time, I have the same considerations as the original poster. What is the hydrogen ratio and how much greater the acidic gas will be after stripping than before? At the same time, where does this acidic gas go? Should dry gas be desulfurized and burned, or is there the possibility and benefit of recycling it into PSA? Also, will the gas phase be entrained in the fractionated oil after the working conditions change? Will the corrosion of the stripper increase or decrease after the working conditions change? Can any master give me an answer?
Do you know which factories are using it?
I am also considering this matter, but I don’t know how to deal with it in the future. I need someone who knows to explain it a little bit.
