Aspen component addition issue

2010-05-12View Original

Thread Content

I want to add a component; the molecular structure was drawn using ChemOffice, and Aspen can also read it in, but the simulation results show that it does not match the group defined by the group contribution method. I’m not sure why this is the case – please advise! Thank you! WARNING: In the physical property system’s functional group generation for the UNIFAC method, it was not possible to complete the process for the component TBP. The following atoms could not be matched: O 1, P 2, O 3, O 4, O 5. The functional groups generated are as follows: Group Number, Number of Occurrences. Group Number, Number of Occurrences: 1015, 3; 1010, 9. This is part of the warning message. The component is tributyl phosphate

It is recommended to take a look at the following: Property Estimation (Lecture Notes) http://bbs.hcbbs.com/thread-436491-1-1.html
