I would like to ask, what software is used for simulation calculations of ammonia absorption?
Thread Content
I conducted simulation calculations for ammonia absorption towers using both Aspen and PROII; the results showed that the heat calculations were incorrect. I wonder what thermodynamic methods and software experts use when performing calculations for ammonia absorption towers?
The simulation for proII is pretty good; there’s a dedicated ammonia property package, and I’m not sure how big the difference is, but it should be within an acceptable range
Which ammonia property package are you referring to? The heat calculation of PROii’s electrolyte model is acceptable, but the version currently in use is not the legitimate one; Aspen’s results show a difference of over 30% in terms of heat values.
There’s a model using acidic water that you can try; I’m not sure what the results will be. You can also give srk and its correction equations a try
Learn* it a bit; currently, there are few accurate and widely applicable ones
Using PRO/II software, which has a dedicated ammonia model, the calculation should be no problem!
Are you referring to the electrolyte pack for PROii?
It should be special packages----Amine
It should be special packages-----Amine
Does this amine package refer to aliphatic amines, and can it be used for calculating ammonia aqueous systems?
For the ammonia solution system, an electrolyte model is sufficient! Are you a beginner?
