The reprocessed oil undergoes heat exchange, a process commonly referred to as \"second stage\". What determines the amount of material in this second stage and the temperature for returning it to the tower? How is the amount of material in this stage determined?

I’ve just started learning catalytic fractionation and still don’t quite understand it
Under normal circumstances, as the amount increases, the temperature decreases! But if the magnitude of your circulation volume exceeds the maximum heating load, then as this volume increases, the temperature will rise as well! Additionally, there is another scenario: once the quantity reaches a certain level, a temperature inflection point appears; beyond this point, the quantity is directly proportional to the temperature! It is recommended that beginners first study the introductory materials on the device, progressing from basics to more advanced topics in order to gradually improve their theoretical knowledge and skills!
Following the design values is the golden rule!
