Hi all,
I have a multitubular catalytic reactor where an endothermic reaction is taking place on the tube side and a heating oil is flowing cocurrently in the shell side of the reactor.
Recently, I have seen a suspected reduced heat transfer coefficient which lead to a significant temperature drop in the temperature profile on the process side in the front end of the reactor. My concern is that, for some result, the heat supplied by the heating medium is insufficient to keep up with the rate of reaction on the tube-side, and a significant temperature gradient in the tube side ccould lead to pore condensation of the species. Therefore I would like to model a radial temperature profile for any axial distance, z, along the reactor to investigate how low can the temperature in the tube reach. How can I determine such a profile then? What are the considerations and equations which I can use?
I would appreciate any help on this matter. Thanks
