Hello Everyone,

I have a general question. I am hoping that one of you could direct me to a good source. Or maybe even help me solve this problem.

We are using a PBR reactor for our process. Our job is to size it which means we are asked to find the volume of the reactor and the number of tubes in it.
I know how to find the volume of a PFR reactor. But I don't know how to find the volume of a PBR reactor. I do know how to find the weight of the catalyst in a PBR reactor. Can I used this weight to solve for volume some how? Or is there a way to use PFR reactor volume to find PBR volume?

Any help would be well appreciated.

thank you.

So we calculated the weight of the catalyst. Then we used the density of the catalyst to find the volume. We found the volume of the reactor to be abot 70 m3. Is this value too large? we are thinking of getting two reactors of 35 m3. Any suggestion guys?

Perhaps someone can help you if you explain what a PBR is in your case.

It is advisable to give as much data about your process as you can, i.e. pressures, temperatures, flow rates, components, what is the purpose of the facility, etc. Better give too much data than too little.
