Such untypical customization of a reactor would call for a custom reactor implementation - essentially any program that will allow you to solve a system of ODEs (Matlab, Scilab, ...) could be used to model a custom reactor like that:

I have a couple more queries on the PFR please. I'm also trying to find the thermal conductivity of the gas flowing through the PFR. Can the reactor profile of thermal conductivity be viewed?

A value can be entered for the wall heat transfer coefficient, but what if the heat transfer coefficient varies along the reactor? Or is an average used?

Another option would be a splitter - split 1/170 off and run it through a reactor. Then to simulate the other 169 tubes, use a stream duplicator that duplicates the product, with a flow controller on it that multiplies the flow rate by 169. Then mix.

I may have the packed tube and the heating/cooling tubes mixed up. It was my understanding that the internal tubes in white represent the heating/cooling tubes within the larger packed reactor tube in yellow, as in this diagram. But I am trying to model multiple packed tubes within a furnace. Doesn't this arrangement make it a single reactor tube?

Thanks you helping.

I would like to know whether there is a solution to modelling a PFR, or more specifically a packed bed reactor that consists of multiple reactor tubes, like a steam methane reformer.

I can only think of modelling a single reactor tube, and then multiplying the product stream by the number of tubes, but then it would be to a different scale with the rest of the process in the flowsheet. Or modelling each tube as an individual PFR unit, but there are over 100 tubes. Is there a function to model the PFR as multiple tubes or to multiply the product stream by the number of tubes?

Many thanks

Andrew
