[Q&A] Catalytic Coking Reformate Blending Version 20170811
Thread Content
What are the operating principles for the catalytic fractionation unit? Answer: Maintain the liquid levels throughout, control the flow rates and temperatures in each section, adjust the heat balance appropriately, and ensure balanced operation so as to produce qualified products.

Stabilize the liquid levels in all areas, and properly control the flow rates and temperatures at each section
1. Adjust and operate based on the reaction volume and reaction depth, separate out the corresponding qualified products, and strive to increase the yield of light oils. 2. Select appropriate heat extraction ratios for each fractionation section to ensure material balance and heat balance throughout the tower. 3. Maintain the liquid levels in each column at the distillation unit at 40-60%, to strictly prevent incidents such as columns being flooded, empty, overfilled, or having insufficient liquid.
1. Adjust and operate based on the amount of material to be processed and the degree of reaction, separate out the corresponding qualified products, and strive to increase the yield of light oils. 2. Select an appropriate heat extraction ratio for each fractionation section to ensure material balance and heat balance throughout the tower. 3. Maintain the liquid levels in each column at the fractionation unit between 40-60%, to strictly prevent incidents such as columns being flooded, empty, overfilled, or having insufficient liquid.

1. Ensure proper thermal balance of the entire tower to prevent overheating that could lead to tower failure； 2. Control the liquid level in V-1203 properly; it is strictly prohibited for rich gas to contain oil and crude gasoline to contain water ； 3. Keep the temperature at the top of the control tower at ≤130°C to prevent over-temperature and over-pressure from causing damage to the tower ； 4. As long as there is catalyst in the settler, circulation within the slurry tower is necessary ； 5. Ensure a certain amount of slurry to be discharged outside and the amount of slurry to be recycled; control the solid content of the slurry at ≤4g/l as required ； 6. The liquid level at the bottom of the distillation tower must not be too high, to prevent pressure buildup due to reactions and vibrations in the oil and gas pipelines ； 7. Ensure that the temperature of the liquid phase at the bottom of the tower is ≤ 360°C to prevent coking at the bottom of the tower and pipeline blockages ； 8. During normal production, when accident-related raw materials are returned to the reprocessing tank, one of the pipelines must remain unobstructed ；
