Thermodynamic amine wrapping problem in proii
Thread Content
The PROII calculation of dry gas desulfurization requires amine packages; however, the available AMINE models in the thermodynamic model can be found in both Special Packages and Electrolyte Models. I used both models in my calculations, but nothing works. Why is that? The amine model from the Electrolyte Models is selected; although it is not necessary to enter amines as components, olefins and alkanes are not suitable for this model during calculations. When using special packages, one must enter the amine themselves, but it is not possible to enter the products resulting from the amine reaction (or it may not be necessary to enter them, but no reaction occurs after clicking ‘run’). Could some expert give me some advice? Thank you!
I use proii to calculate the dry gas desulfurization process, employing the amine model from the special packages – the calculations work fine, right? For the amine model in special packages, there is no need to enter the product after the amine reaction! You say it can’t run; it’s probably a problem with other settings.
Could someone upstairs send over a simulation file for desulfurization so I can learn from it?
Several software packages for calculating thermodynamic amine properties, such as Pro/II, Aspen Plus, Hysys, and ChemCAD, have problems – I’m referring to their own software – with significant calculation errors (I have checked this). Calculations for thermodynamic amine packages are accurate; there is a very reliable software called Amsim, which is designed specifically for such calculations. It is integrated into Pro/II 6.0 and 7.0 (I haven’t used version 8.0), and the module is named Amsim. I recommend using it.
There are issues with Amsim simulating the desulfurization of liquid hydrocarbons
