Catalyst concentration at the inlet of the cyclone separator in the catalytic regenerator
Thread Content
I would like to ask the experts: what is the catalyst concentration at the inlet of the cyclone separator in a catalytic regenerator? Concentration in the dilute phase? Thank you!
Cyclone inlet: 2-10 kg/Nm3; the cyclone inlet is located at the upper part of the dilute phase.
Generally, the density at the inlet of the regenerator cyclone is between 5–10 KG/m3, while the dilute-phase density in the regenerator ranges from 10–20.
The design of each device varies, so it’s difficult to give an exact answer; however, there should be a range. Personally, I think it’s between 2-13 Kg/m3
