How to measure the catalyst circulation rate in catalytic cracking
Thread Content
I want to calculate the catalyst-to-oil ratio for catalytic cracking, but the technician said that it’s not possible to measure the amount of catalyst being circulated. I checked some literature, and it seems that temperature measurements are used for this purpose, but the errors in practical applications are quite large. Does anyone have any good methods?
There shouldn’t be any at the moment; if there were, patents would have been issued by now
The catalyst circulation rate is calculated based on the thermal equilibrium between the two units, and taking into account the adsorption heat and desorption heat of coke, there are slight differences in the calculated values for this rate; however, these differences are not significant. It is recommended to refer to \"Calculation and Technical Analysis of Catalytic Cracking Processes\" for more details.
Well, thank you. This method is used quite often, but it’s too troublesome and inaccurate; there’s no better alternative, such as solid flow meters or something like that
