User kinetic subroutine

User kinetic subroutine

User kinetic subroutine

(OP)
Hi,

I need to write a fortran subroutine to insert the reaction kinetic to Aspen plus because this kinetic is in function of component activities instead of component concentrations. I haven't any idea, for this reason I need a similar example in which the kinetic expresion are in function of component activity. Someone know where I could find it?.

Best regards.

RE: User kinetic subroutine

Hi,

I'm looking for a way to use a kinetic subroutine in the Aspen Plus module RADFRAC.  I've tried using the Aspen Plus FORTRAN templates USRKIN.f and USRKNT.f but my problem is trying to get Aspen to run them in the in-line Fortran section on the FORTRAN flowsheet.  I've checked the box on the SETUP-Simulation
Option-System menu under FORTRAN compilation options to:
      "write inline FORTRAN to a subroutine to be compiled and dynamically linked"

but I still get an error that I'm not allowed to use subroutines in the in-line FORTRAN box.  Does anyone know how I can include a kinetic subroutine in Aspen Plus?

                         Thanks in advance for any help,
                         Christina
