1. The main function is to raise the starting temperature for the regeneration of the coking drum, thereby improving the efficiency of catalyst regeneration. 2. The second function is to ensure the catalyst distribution in the upper dense phase and the lower coking tank, thereby ensuring good fluidization. 3. Additionally, it facilitates the recovery and utilization of heat.
1. Adjust the amount of catalyst entering the external heat exchanger, which is also the amount of heat extracted. 2. Adjust the temperature of the coking tank. 3. Adjust the material level of the two dense materials.
Liaifeng, regarding the third point, I would like to ask: does \"facilitating heat recovery and utilization\" mean using an external heat extractor to remove the excess heat from the regenerator?
My understanding is that it doesn’t refer solely to the heat extraction section of the external heat exchanger; rather, it involves a systematic consideration. Improving fluidization is even more beneficial for heat extraction!
Okay, thank you: handshake
