How to calculate the pipeline speed for continuous reforming?
Thread Content
May I ask how to calculate the pipeline speed improvement? The differential pressure of the dust collector is a bit high now; I want to check if it’s caused by an excessively high line speed.
Axens keeps the catalyst lift rate at approximately 2.5–3 m/s. Different manufacturers of process packages use different calculation formulas; you can look up the formula provided by the manufacturer of your process package. It is specified in the control instructions for the special circuits of the instrument.
There are calculation formulas in books on catalytic reforming processes and engineering; you can refer to them.
Hengli, Fujia, and Tenglong all use the Axens process package. Not at a constant force.
Increasing the line speed is proportional to increasing the catalyst circulation rate; otherwise, the material level in the equipment cannot be maintained. If there is a high amount of dust, reduce the catalyst circulation rate appropriately depending on the degree of carbon deposition on the catalyst
