UmeshMathur:
Here I am providing you all of my experimental data of N-(2-Hydroxyethyl)ethylenediamine at 40 degree C. I am also providing the Predicted data with UNIQUAC equation with four parameters, and I got % AAD 3.02. My initial guesses for all four parameters were, a12=-1.568, a21=2.956...
Umeshmathur,
Thank you very much.
Sorry I didn't mention about the temperature. The experimental data are available at 25, 40 and 50 degree C. Still there is a problem, I couldn't abtain a good result. I would like to inform you that I tried to solve it by adding temperature dependent...
Umeshmathur,
I forgot to mension in my previous post that my system is aqueous, i.e. first component is water and second component is N-(2-Hydroxyethyl)ethylenediamine.

Thanks,
My component is N-(2-Hydroxyethyl)ethylenediamine. First i want to try all of my calculation with this component, then after i will try on actual one. if possible then please double check these values, because I am not sure whether i calculated it correctly or not.
For...
UmeshMathur,
Can you please suggest any basic criteria for initial guess of binary parameters in Aspen Plus Regression tool.. Because all the time I am getting different parameters if my initial guess is different.
Thanks

UmeshMathur,
Thank you very much
I am using 2004.1 version of aspen plus. Regarding the identity of component, its a alkanolamine, and i don't want to disclose anyother identity of this chemical, hope you understand this thing. If possible to make any comments for alkanolamines, please let me...
UmeshMathur,
Thank you very much for your help. I need more support from you, In Aspen Plus regression tool, i found four options for each UNIQUAC and NRTL model, like (1) "UNIQUAC or NRTL"/Hayden-O'connell equation of state with Henry's law, (2) /Nothnagel equation of state with Henry's law...
Anybody please tell me, which aspen package contain a regression module for NRTL, UNIQUAC models. Actually I have "Aspen One" software, and it has Aspen COMThermo: Workbench tool, in which i found fluid phase regression, but there is no any description of NRTL or UNIQUAC models. so please give...
DickRussell,
Do you have any idea about the models that are used for fitting the heat of mixing data? if you know, please help me abt this thing, and one more thing i would like to share with you is that, i used NRTL equation to fit the data, and i got 2% AAD. (i used the excel solver for...
Hi to All,
Happy New year to All of you..
Can anybody help me for determining the paratmeters of UNIQUAC equation? I want to use this equation for the prediction of experimental Heat of Mixing Data. This thing is new for me, so i want to start it from basic level..
Thanks

Actually, I am looking for the new alkanolamines apart from MEA, DEA, MDEA. As you know these amines are very common, so i am looking for the new alkanolamines that are competitive with MEA, DEA, MDEA and more efficient to capture acid gases like MEA. so if possible, then please provide the list...
