Summary Post for Refining Technology Exchange Area (35) – Settlers

2009-03-02View Original

Thread Content

I have compiled all the posts related to settler technology within the oil refining technology exchange area, so as to make it easier for everyone to search, save time, find what they need, and assist others in solving problems! Floor 1: 1–25 (Click on the title to access the hyperlink). 1. The centrifuge in the settler of the catalytic cracking unit. 2. What medium is generally used for instrument backwashing in settlers? 3. Pressure drop of the settler; 4. Abnormal pressure drop of the coarse spin in the settler of the 600,000 tons/year RFCC unit? 5. Let’s discuss whether coking in the settler of heavy oil catalytic cracking units is a serious issue 6. The single-stage pressure drop in the catalytic settler reaches 7–8 Kpa. 7. Pressure fluctuations in the catalytic settler. 8. What are the reasons for the wear of the valve plates in the centrifuge of the catalytic cracking settler? 9. Which factors are related to the wear of the valve plates in the catalytic settler? 10. Temperature distribution in the settler. 11. What is the reason for the generation of large amounts of fine powder when the catalyst passes through the lift pipe and the centrifugal separator in the settler? 12. Regarding coking in the heavy catalyst settler. 13. The relationship between settler pressure and the material level in the stripping section. 14. Methods to reduce coking in the settler. 15. The herringbone baffles in the catalytic cracking distillation column and those in the stripping section of the settler. 16. Friends involved in catalysis, please discuss: Based on which density points is the inventory in the heavy oil settler calculated? 17. Quality of catalytic operation and the coarse spinning in the settler. 18. How to reduce coking in the settler. 19. How to prevent coking in the settlers and spinners of catalytic units. 20. The pressure tapping point used for measuring the volume of material in the reaction settler is damaged. 21. How to avoid large amounts of catalyst from entering the distillation tower in the settler during the initial operation of a catalytic unit? 22. Problems with the settlers and regenerators in catalytic units. 23. After shutdown, the coke on the grid in the stripping section of the settler catches fire. 24. What should be done if oil and gas from the settler enter the regenerator? 25. Severe leakage in the catalytic cracking settler. Last edited by Final Fantasy on 2009-3-2 21:12.]
