Choice Of Co-Current Vs Countercurrent PBR Reactor Jacket

Choice Of Co-Current Vs Countercurrent PBR Reactor Jacket

Choice Of Co-Current Vs Countercurrent PBR Reactor Jacket

(OP)
My notion was that we should use counter current in the jacket because of efficiency but my friend said



"The co-current system is often used in industry for example, protection of acid corrosion economizer, temperature cross-over, etc."



In our case the case of this PBR, the inlet temperature is 150C, but the MP steam temperature is higher than 150C(MP is normally 10~25bar), so is counter current is not possible?



Does anyone has any reference or code for this?

PBR?

Good Luck,

Is your reaction exothermic or endothermic?

RE: Choice Of Co-Current Vs Countercurrent PBR Reactor Jacket

(OP)
Highly Exothermic. Partial Oxydation.

RE: Choice Of Co-Current Vs Countercurrent PBR Reactor Jacket

It depends on reaction kinetics and what you are going to do with the heat.

It seems strange to use medium pressure steam to cool a reactor. Perhaps you mean condensate?

Will the reaction run out-of control if it gets too hot. Still too many unknowns to answer your question.

Thank you for your reply.

Yes, runaway reaction occurs if the reaction is not controlled by a large amount of inert.
