Hi Everybody,

I am trying to simulate an existing liquid LPG sweetening process by using Hysys liquid liquid extraction module. I dont  know what Pkg is suitable for property package selection.
The conceptual process is as follows:
A liquid LPG stream (@ 44 ºC and 10 barg) 200 m3/day enters to an existing column and is sweetened by using  2 % wt caustic solution.

 2NaOH+H2S...>>>Na2S+2H2o
I hope you can help me; however I have not been able to get convergence.
Has anybody simulated this kind of process?
Best Regards!

You really shouldn't use Hysys for that. You will want an electrolytic package such as the Caustic Treating Property package in ProMax. I use ProMax for Caustic Treating designs for Refineries and am quite happy with it.

Is there any exenstion for Caustic Treating?
