Operation of the reaction regeneration system
Thread Content
What precautions should be taken during operation of the reaction regeneration system after pressure increase or decrease, and what adjustments should be made in the operation?
1. The conversion rate will change； 2. The target product will change ； 3. There will be changes if the regenerator burns out ； 4. High pressure accelerates coking.
1. Increasing the pressure can correspondingly increase the coking intensity of the catalyst, and the bed temperature will change； 2. Increasing the pressure will correspondingly change the oxygen partial pressure in the regenerator. 3. There are no significant changes in the target product and conversion rate as mentioned above
What precautions should be taken during operation of the reaction regeneration system after pressure increase or decrease, and what adjustments should be made in the operation? First, regarding pressure increase: 1. It is necessary to properly control the pressures of the three devices to prevent mutual influence ； 2. As pressure increases, the catalyst circulation rate will definitely change ； 3. As pressure increases, the feed rate will definitely change ； 4. An increase in pressure definitely causes a change in the conversion rate ； 5. An increase in pressure definitely leads to changes in regenerator charring ； 6. An increase in pressure definitely causes a change in the partial pressure of oil and gas ； 7. There is certainly a change in the equipment for increasing pressure. A decrease in pressure leads to a similar situation inversely.
