Catalytic reaction fuel injection conditions
Thread Content
After the catalyst for the catalytic reaction is installed and fluidization is completed, what are the key points to consider regarding fuel injection into the reaction vessel? Are there any requirements regarding the overall temperature of the settler? I hope to receive guidance from all the teachers. Thank you!
Note: 1. The slurry circulation is normal. 2. The feedstock circulation is normal, and the pressure in the collection tube is normal. 3. The pressures in both reactors are normal. 4. The operation of the air compressor at low speed is normal. 5. The regeneration temperature is above 560 degrees, the temperature at the outlet of the lift pipe is above 480 degrees, and it is preferable for the temperature at the top of the settler to be above 350 degrees. 6. The liquid level in the external heat recovery drum is normal, allowing the temperature load of the regenerator to be adjusted.
5 The regeneration temperature reaches around 660 degrees
Is the settler temperature kept above 350°C to prevent coking or to protect the equipment?
The key is the inlet temperature of the reactor centrifuge, which must be above 450 degrees.
Before injecting fuel, the two reactors must operate in a fluidized state properly, with the reaction temperature above 500 degrees.
The raw material nozzles should be aligned, starting slowly and then accelerating
The reaction temperature must be above 480 degrees; otherwise, the material will be cut off. The solid content of the slurry is analyzed once per hour to monitor changes in the total amount present, as well as the pressure drops in each cyclone
