I'm a stage 3 student working on my final year design project. I am required to design a methanol synthesis reactor. I have based my design on a packed bed reactor with evaporating water as cooling.

I have tried to model one of the tubes using PFR design equations and an energy balance. How do I find the number of tubes and the tube diameter?

 

Thanks

For a certain (required) catalyst volume the choice of reactor diameter is an economical choice.

 

The bigger the reactor diameter the lower the gas side pressure drop will be. However the bigger the diameter the lower the gas side heat transfer coefficient and the bigger the required wall thickness. For a given catalyst volume the reactor with the biggest diameter is the most expensive.
