CAPE-OPEN

Hello,

I am getting these messages when solving this flowsheet:

- Invalid floating point operation
- error: calculate failed for unit IAT: run failed: Failed to calculate logFugacityCoefficient: CalcSinglePhaseProp failed: Property evaluation using equation of state failed: Total composition is zero

Any solution for this?

The issue is being looked into

To make this run, you added Sulphur to ChemSep's PCD files, correct? Can you provide the PCD file?

Yes, I added Sulfur and Sulfuric acid.

It doesn't allow me to add the extension pcd to this forum. I will send it to your email.

Thank you Jasper and Dr. Ross for the reply.

I have checked and the gas feed is at the bottom and liquid at the top of the column.

Yes, I know I can't modify chemsep databank of compounds so I created my own pcd file and added the rest of the components I need and saved it in another location.

Hi, I´m trying to do the same simulation but I can´t add the properties of sulfur, it shows multiple errors and missing data, could you send me the pcd file that you use on your program please?

If you are using TEA - you can just load Sulphur (S8) from Solids.pcd. Hit the Browse button:
