FCC pre-rising section temperature
Thread Content
What are the minimum and maximum temperatures for the coaxial pre-lift section? What are the disadvantages of being too low or too high? I hope to receive guidance from all the teachers!
As long as the reaction temperature is met, a lower temperature in the pre-raising section and a higher oil-to-agent ratio are acceptable; however, if the temperature is too low, it will affect the vaporization and cracking reactions upon contact with the feedstock, potentially leading to coking in the riser or the settler.
