Residence time with change in volume
Residence time with change in volume
(OP)
Hi all,
I have a plug flow reactor with a network of reaction with complex reaction kinetics taking place.
There is a net increase in the total number of moles at every step(of modelling).
The reactor is assumed to be isothermal in operation. Change in total moles implies change in volumetric flow rate at the end of the reactor.
My question is
How do I calculate the residense time in this case?
the normal way, ie: reactor volume/volumetric florate doesent work here (?).
Thanks in advance

RE: Residence time with change in volume
In the real design you are specifying the reactor size and the feed rates. Outputs will have to take care of themselves. If this is just theoretical work and you want to have a residence time to compare diferent conversion rates then just define the residence time as reactor volume/volumetric feedrate. It is not going to matter whether or not it represents the real residence time of a molecule or not.
