[dwsim-users] reactor application - ethyl acetate

[Hector P. <hpe...@gm...>]

Hi,

I am trying to replicate the following ASPEN tutorial to set up the liquid
reaction for ethyl acetate formation from ethanol and acetic acid using
different types of reactors:

Unfortunately, only the Gibbs reactor yielded any result with a ethyl
acetate flow that was 12 kmol/hr lower than the ASPEN simulation. The only
differences I can see is that the ASPEN simulation uses the NRTL-hoc,
whereas my simulation uses NRTL.

The conversion reactor had zero conversion and both the PFR and CSTR
reactors gave the error: "The given key was not present in the dictionary."
I'm not sure what this means. I tried different thermodynamic models
besides NRTL with no avail.

I will send my simulation file attached.

I would really appreciate any light on the matter.

Obrigado!
