Issues regarding the binary interaction parameters in ASPEN simulations

Thread Content

I’m a newcomer; I have some questions for everyone. The NRTL property method was chosen for the simulation; what do all those codes in the blue circles in the diagram mean? Do I need to check each item one by one? For some of the substances marked with red circles in the diagram, the AIJ and AJI values are 0, while others have numerical values; is it necessary to check the correct data for verification? Where can I find the data? Above the red circle in the image there is a label that says “SOURCE”. I can see several options such as “APV86 VLE-IG”, “APV86 VLE-LIT”, “APV86 VLE-RK”, etc. What do these mean? If the selection is changed, parameters such as AIJ and AJI will change; then how should this “SOURCE” be chosen? There are quite a few questions; I hope everyone will be kind enough to offer their advice! Thank you very much
