Is the poster trying to calculate the line speed on the lift pipe side? I remember that it seems one should first calculate the catalyst circulation rate, and then estimate the flue gas volume based on a certain ratio

Each ton of recycled catalyst carries 1-2 kg of flue gas.

We calculate it based on 0.00135 per unit of catalyst circulation volume

Some sources mention this value; I’m not sure how it was determined
