Are there parameters for acetylene and NMP solvents in Aspen?
Thread Content
In the project, there was an absorption tower whose components contained a high level of acetylene; NMP was used as the solvent for absorption, but the absorption of acetylene was not effective. What physical property methods should be chosen? I’ve tried many methods, but the absorption results have not been satisfactory. I suspect that there may be no interaction parameters for acetylene and NMP in the physical property database.
Take a look for yourself – it will be over soon. Is there any need to doubt that?
Aspen contains the physical property parameters of N-methylpyrrolidone (NMP), which can be used for calculating the absorption of acetylene. There is also NMP in PROII; both software packages can be used.
I think it should be corrected; some parameters may not be accurate at normal pressure
