Re-catalyst oil ratio issue
Thread Content
I keep feeling that the fuel-to-oil ratio in my unit is a bit low, even though the opening degree of the regeneration slide valve is much larger than in the previous cycle. (But from the perspective of heat conservation: much less steam is generated by the pre-cooler, the temperature difference at the raw oil nozzle increases significantly, less terminator is used, and the reaction temperature remains relatively low); while the amount of steam generated through external heat extraction increases considerably when there are no significant changes in the properties of the raw materials being processed. I feel that the oil-to-agent ratio is a bit low now. What are the disadvantages of having an excessively low oil-to-agent ratio? I would appreciate some guidance from Teacher Wang, thank you!
As long as your product distribution is proper and the yield is satisfactory, there’s no need to pursue a high oil-to-reagent ratio; a higher oil-to-reagent ratio leads to increased coking, which may cause clogging in the settler and affect the operational cycle
