Hello everybody,

I wish i can find my answer here 
 

I design a  sweetening unit to remove CO2 only by MEA 
here's the problem , I have to get equilibrium relation VLE 

Where can i get it ? 
And if i can get using Hysys , How can it be done ? 

Thank you

Have you tried asking Aspen for it?

use the DBRAmine Pkg in UniSim or HYSYS.  it can give you accurate calculation of VLE. one way you can do it is just creating a stream, set P,T, and compositions.  it will be easily find out the equilibrium state.  Be noted that HYSYS has a new module called "acid gas cleaning" which from my experience is not as good compared to its old DBRAmine Pkg.
