Hi! I would like to know if it's possible to create an hypothetical component on hysis, by it's structure. My component is a complex of Ag+ with an olefin (ethylene or propene)
I am not sure what is the structure of your component, but this might be helpful:
You can create a hypothetical using the UNIFAC model structure builder. You need to know the exact component groups in your compound. Refer to any thermodynamic equilibrium text for information about UNIFAC model to find out if your compound components are supported by the model.
Otherwise, only the regular hypothetical component creation methodology is available.
To the best of my knowledge all the Hysys users can register at Aspentech and get an access to their <<knowledge base>>, which helps to solve a lot of your needs. Besides, there must be some Hysys operating manual as a group of .PDF files. This manual contents al lot of exercises for the typical plant operations. It may take the significant time to go through them but this’d be a good start. I'd also mention that ease in use of Hysys is highly dependant on your chemical engineering knowledge and working experience.
To set out a reliable hypothetical component you must be well aware of its termodynamic properties.
