Can someone explain the equations and the steps involved in designing a fluidized bed reactor. I have the flow rates (for ammoxidation of propylene) going in and coming out of the reactor, but i don't know how to size the reactor based on this inputs. Kindly help me. Thanks & Regards, Raj Mehta

There is a small section on fluidized bed reactors from page 1009 of Encyclopedia of Chemical Processing (Vol 2)

You could also read Chemical Reactor Design and Control by William Luyben

Best is to read from page 313, Chemical Process Design - Computer-Aided Case Studies by Alexandre C.Dimian and Costin Sorin Bildea

You need to know a bit about the reaction kinetics to get the proper size reactor. The diameter is set based on fluid flow and fluid bed mechanics and the height is determined by the reaction kinetics. And there are cooling tubes within the bed, too.

Hey bobby, thanks for your input. I agree with whatever you said. It would be great if you could share some equations/references/steps involved in designing. I have actually done a lot of googling about fluidized bed reactor design and sizing, but couldn't find any. 

 

Your help in this matter would be greatly appreciated.

 

Many thanks,

Hi, you will find those books in post 2 very useful. They show the equations/references/steps and are even specific to your problem: ammoxidation of propylene. It would appear you have not found and read those books yet.
