What are the effects of high and low pressure differences across the two catalytic converters, when no reverse pressure difference is present?
It mainly affects the driving force for fluidization; a large pressure difference between the two devices leads to better fluidization~
A high differential pressure between the two devices increases the catalyst circulation rate, while a low differential pressure is not conducive to catalyst circulation. Differential pressure is generally operated at a fixed value, and is not adjusted frequently as an operating parameter. Frequent fluctuations in differential pressure are not conducive to the safe operation of the unit, especially regarding pressure balance, which is the most important of the three balances in catalytic cracking.
