The slurry has a high solid content
Thread Content
The solid content of our slurry is as high as 49; the slurry pump stopped operating due to overload once. Currently, a large amount of material is being discharged externally, and raw oil is being fed back into the tower. One thing I don’t understand is why the reaction depth needs to be reduced – is it to lower the temperature in the distillation tower so that the heavier components can be removed? I’m not very familiar with equipment; could you explain it to me?
Lowering the reaction temperature increases the oil slurry yield
If the solid content doesn’t stop decreasing, it’s better to shut down operations as soon as possible. Prevent the accident from spreading
What high temperature can the catalyst withstand? What will happen if it is exposed to temperatures above 750 degrees? Will continuous burning cause the catalyst to burn out, or will the constant injection of low-carbon fuel lead to its damage?
You can search on the forum and take a look at this post: The solid content in heavy oil catalytic slurry varies from time to time. https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1407026 (Source: Haichuan Chemical Industry Forum)
Reduce the reaction depth, send more slurry back to the refinery for reprocessing, discard more slurry, and lower the solid content. I wonder if there will be any agent leakage
There must be a performance enhancer. I suspect the gas flow rate was set too high; our gas flow meter is broken, and for a while it was set at 50%. It could be steam that has carried the catalyst to the anti-backflow cone and the flexible connection areas, resulting in leakage
Continuous spraying will definitely damage the catalyst
The effect of gas vapor isn’t that significant; it’s the centrifugation that’s the problem
The solid content remains high; there are problems with the internals of the settler, and these issues are difficult to resolve, so shutdown for maintenance is necessary
