As far as I understand, what you are saying is that I have no choice on calculating the reactor operating pressure BECAUSE a lab scientist will find out the best operating condition for that reaction. And Chemical engineers have to meet those conditions in any way by designing proper reactor. Am I right? If so, that is not what I was wondering.
I have heard that Equipment and Piping size can be affected by its operating pressure, because the actual vol flow rate will be smaller at high pressure. (Let's say gas flow only) My thinking was based on the volume flow rate change according to operating pressure change. Let's say the reformer can be operated in a small range of operating pressure, 18.39~20.50 bar. Please take a look at the attached table. I calculated this by the Gibbs reactor Aspen plus v.8.4 simulation program.
FEEDGAS3 --> Refomer1(20.5 bar) --> EFFLU3
FEEDGAS4 --> Reformer2(18.39 bar) --> EFFLU4
As shown in the attached Aspen printout table, the actual Vol. Flow rate is 17% larger at 18.39 Bar than at 20.50 bar. So I could imagine the cross-sectional area of the Reactor and Pipings have to be enlarged in order not to increase space velocity of the gas.
