The mass (molar) balance is not tally
Does anybody knows why there is a slight difference in the molar flow of vapor also liquid? I got vapor mass flow inlet is 150 mol/s and outlet is 149.521 mol/s while liquid mass flow inlet is 50 mol/s and outlet is 50.4786 mol/s.
I knew that this must be related to the thermodynamic model. Can someone explain a bit more detail.

Can you please share a screenshot of where you see the vapor molar flow at the inlet to be 150 mol/s? May be you can take a screenshot, put in your google drive and share the link here as the facility of directly uploading a image is not available.
However I don't face this issue. If you click on the feed stream entering the flash, go to Results>> Phase Properties >> Vapor >> Molar flow rate, it shows as 149.521 mol/s and the same flow rate is displayed in the outlet vapor stream.
Here is the link, I marked the difference:
