Coaxial single-stage countercurrent regenerator
Thread Content
How is the catalyst circulation rate calculated in a coaxial single-stage countercurrent regenerator during normal operation? How is the rotational speed of the regenerator centrifuge line calculated? How is the rotational separation linear speed of a settler calculated? How to determine coking at the raw oil nozzle?
The catalyst circulation rate is determined based on heat balance calculations! Regenerator centrifugal line speed: the volumetric flow rate at the regeneration temperature, based on the amount of steam required for vaporizing the feedstock, stripping, pre-raising, etc ； Also, the centrifugal separation inlet area and so on have been calculated! Settler centrifugal separation linear velocity: Convert it to the volumetric flow rate at the settler’s temperature! Coking at the raw oil nozzle: the amount of char formed will decrease, and the temperature of the regenerator will drop!
Is there a specific formula? I completely understand what you mean. Thank you.
There are many formulas; it’s best for you to find a book.
