Hello Aalluu.

 

Do you have any simulator?

I am selecting 'Electric-NRTL-RK' model in Aspenplus.

But it is difficult to set about component.

Thus, You need to find manual of electrolyte model in Simulator.

_{I tried using UNIQUAC for your system. HYSYS message window  stated UNIQUAC doesn't have BIP's for a few components.}

_{When I selected PR, it says it's not recommended for a few components.}

_{PRSV did not indicate any error.}

 

_{I would recommend you study this topic further through literature. It will take time, but it is worth it.}

 

_{You may also contact AspenSupport team to provide you with ready-made answer.}

 

_{Most people I know in this business (including myself) trust Hysys results, only if the results match with some reference system.}

 

_{All the best.}
