Stirring towers and fractionation towers of hydrogenation units
Thread Content
The sulfur content in diesel is less than 5, but that in gasoline is above 20; sometimes it even reaches 50. Are there any effective methods or approaches to reduce the sulfur content in gasoline to below 20?
Add a desulfurization tank and a washing tank; the alkaline solution can be introduced via catalysis
Is the fluctuation range of the reaction temperature large?
It is necessary to first analyze what type of sulfur it is – thiol or hydrogen sulfide – and then adjust the temperature of the stripping tower or the reaction based on those results.
It’s just the most ordinary diesel hydrogenation process
Well, I’ll give it a try and see how it goes
At present, the temperature of the stripping tower can only be reduced, not increased
