Inert compound that reacts

[mjparra]

IMPORTANT: This section is for code-related bugs. For usage issues, please go to the Support Forums.

Describe the bug
There is a conversion reactor (isothermic). One of the compounds is Nitrogen, it doesn't appear in any of the reactions, but in the outlet stream, Nitrogen is only 43% of the one that enter.
There is another issue: The heat load obtained is NaN, must it not be 0?

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior
The amount of Nitrogen must be the same in the outlet stream.
The heat load must be zero, since is isothermic.

The version I'm using is v8.3.4 for Windows.
The best way you can review the problem is sending the file from dwsim, but I didn't find how to send it.

There you can upload a zipped version of your DWSIM simulation

@mjparra you can zip the simulation file and drag it here to attach.

I already post my question in sourceforge, according to a suggestion I received. But I attach the file here, this is a file that shows only the part with the problem. I appreciate ;your help. Martha Parra

When I check the third stream,that it must be zero, I found, that it appear a very small negative number for mass flow, and -infinite for molar flow, then it is impossible to calculate heat load: Master Property Table Object 16 15 14 Temperature 577 577 577 C Pressure 204.75 204.75 204.75 kPa Mass Flow -3.35E-16 1.51069 1.51069 kg/h Molar Flow #¿NOMBRE? 0.157284 0.0852586 kmol/h Volumetric Flow 0 1.51E-20 2.94432 m3/h Molecular Weight (Mixture) 0 9.60482 17.7189 kg/kmol Specific Enthalpy (Mixture) 0 0 1520.04 kJ/kg Molar Flow (Mixture) / Nitrogen NaN 0.00035446 0.00062562 kmol/h Molar Flow (Mixture) / Hydrogen NaN 0.105696 0 kmol/h Molar Flow (Mixture) / Water NaN 0 0.019428 kmol/h Molar Flow (Mixture) / Carbon monoxide NaN 0.0359574 0 kmol/h Molar Flow (Mixture) / Carbon dioxide NaN 0.00079934 0.00141083 kmol/h Molar Flow (Mixture) / Methane NaN 0.0135867 0.0598689 kmol/h Molar Flow (Mixture) / Ethane NaN 0.00084879 0.00374016 kmol/h Molar Flow (Mixture) / Propane NaN 4.20E-05 0.00018513 kmol/h Energy Flow 0 -1493.59 -2153.09 W Martha Parra

@mjparra I've already fixed the issue, it was an error in the overall mass balance. aac6d31

it will work in the next update/version.

[mjparra]

I appreciate your dedication to solve the issue. When can we get an update on this topic? Thanks a lot, Martha Parra
