When adjusting the processing volume of the catalytic unit, adjust the initiator mist vapor
Thread Content
When adjusting the processing volume of the catalytic unit, are the other feed streams (termination dose, amount of atomized steam, pre-heated dry gas, etc.) adjusted accordingly? Also, what is the approximate proportion of each type of feed you use?
Generally, the amount of steam used for atomizing the catalytic feed is 5% of the feed volume; if the feed volume is too low, this ratio is not applied, and instead more steam is used for atomization

The amount of atomized steam is generally controlled at 2-4% of the processing volume; no adjustment is necessary when making minor changes to the feed amount! But I remember it was said during the training that there is a minimum value to ensure the lowest linear velocity in the lift pipe! So, in general, don’t set it too low! Termination agents generally adjust the flow rate based on the product distribution; sometimes, when the processing volume is low, it is necessary to increase the dosage of the termination agent! The approach to adjusting the pre-heated dry gas is similar to that used for atomized steam, and this can serve as a reference; however, the proportions must be determined based on the specific equipment in use!
Hmm, I see. We usually don’t make adjustments here
Thank you for the explanation; I’ve learned another piece of knowledge
We do not adjust the amount of vaporized steam or the pre-lift dry gas; the termination dose is adjusted according to the circumstances
