Exit stream = Inlet stream no reactants consumed, what might be the cause of that?
It is a bit difficult to answer your question without knowing what exactly you have done. My suggestion to you is to check all the inputs your gave to CSTR and also from the Help in ASPEN, check the stream type for LHHW kinetics. maybe the operating points you are using is out of range or you are applying this kinetics to the stream type which could not be dealt with it. Try to find a similar sample model in ASPEN tech page and compare your case with the sample model. You will figure it out for sure.
thanks very much for the answer yeah I figured it exactly, the reaction conditions I gave vaporised everything while my input condition was liquid phase which means that there were no reactants to satisfy my equation in liquid phase
1- Check that you have truly introduced LHHW reaction to the Aspen plus.
2- Check operating conditions and phases
3- Check the units of kinetic coefficients and their values
