Which parameters are controlled for the clarified oil of coking feed slurry?
Thread Content
I wonder if any of the coking units you are familiar with are used for processing slurry oil to produce clarified oil? Which indicators are controlled, and what are the control values? Through what efforts are these indicators achieved
Jinzhou Petrochemical is processing catalytic slurry to produce needle coke.
Does this impose high requirements on the slurry? Are there various specifications that need to be met?
Apart from the solid particles it contains, which can act as coke nuclei in the coking furnace tubes and cause coking, there are no other adverse effects of the slurry. The high aromatic content in the oil slurry gives it solubilizing and coking-dissolving properties, which are highly beneficial for the coking reaction (increasing liquid yield) and reducing coking in the furnace tubes. So there is only one requirement for the indicator: ash content.
The ash content in my oil slurry is quite high. How can I remove the ash from it? Is it necessary to use some equipment for this?
Asphaltene, ash, moisture – three elements that need to be controlled
Add slurry sedimentation agents to reduce separation and minimize the wear on equipment such as furnace tubes and pumps caused by reprocessed oil slurry.
After blending, as long as it does not affect the quality of the coke product, there are no parameters that need to be controlled, after all, the amount used is small； If the ash content is high, use less of it in the mixture
It affects the quality of coke; regular control of ash content is necessary to regulate its addition amount
