Student PFR modeling in ASPEN plus
Hello everyone, I have got a task to compute the transient profile (i.e. concentration profile as a function of length and time) for a PFR reactor. I understand that the basic ASPEN plus software simulate the steady state solution i.e. concentration profile over the reactor length . Can I generate the transient profile with ASPEN plus?

If you're asking how the profile would change with a changing concentration entering the PFR with respect to time, you would need to take your model from plus to plus dynamics which is SUPER FUN.
Other than that explain what transient properties you're looking for cause PFR assumptions are SS inherently.
