Regarding the issue of oil adjustment
Thread Content
We currently have a batch of heavy gasoline with a final boiling point of 250°C, whereas the requirement for gasoline is that its final boiling point be below 205°C. Can this heavy oil be added to gasoline as a blending component? I don’t quite understand this, so I’m asking everyone for help. Thank you!
No, the final boiling point of the blended gasoline is determined by the heaviest components; in other words, even after adding lighter components, the final boiling point remains at 250
Adding a little dry ingredient will also result in 250.
Re-refining and distilling it again yields pretty good results
Well, I’m a beginner. Based on common reasoning, I thought that adding reconstituted components would work, but it turns out it doesn’t. According to you, if it’s to be used as a component in gasoline blending, its dry point must first be below 205°C, right?
Right:):):):):):)
What really concerns me is where this heavy gasoline comes from; its final boiling point is as high as 250, and it’s not clear what the distribution of its boiling range is
The 90% level can be reduced, but the dry point remains unchanged after adding light components, so it cannot be adjusted.
Actually, the heavy gasoline we have is what remains after the useful components have been separated out; it mainly consists of C10+, with a small amount of C9 as well. We wanted to use this portion of oil as a component in gasoline blending. But according to what you say, this oil definitely cannot be used for blending, as it contains too heavy components. So this portion of oil can only be used as a diesel component, which results in a significant reduction in efficiency.
Oh, I see, you’ve learned it then. Thank you
It seems we can only switch to diesel; it can be sold when there is a good profit margin
