What impact does the use of coker naphtha as the feed in the high-low parallel dual lift tube reactor of our plant have on the product distribution and properties?
Pay attention to the styrene content, sulfur content, and the content of C4 components in the liquefied gas.
Has the liquefied gas yield increased compared to before?
There was no significant change in the liquefied gas yield; the octane rating of gasoline decreased, while the gasoline yield increased!
The olefin content in gasoline decreased, its octane rating dropped, but the yield of gasoline increased by two points!
There was no significant change in the liquefied gas yield
There is no significant change in the dry recovery rate of liquefied gas
What should the temperature for a mild reverse reaction be? Around 550 is suitable
My unit also features twin lift columns; coker gasoline enters the bottom of the heavy oil lift column via the pre-lift dry gas line. Both the yields of gasoline and liquefied gas increase, while the yield of dry gas increases only slightly. The octane rating of gasoline is not significantly affected either, but the economic benefits are substantial.
After making such adjustments, it is necessary to monitor the changes in sulfur content in the steam
