I want to simulate sour water stripper for optimising an existing column. Inputs are required regarding

1. Property package to be used.
2. Any values for H2S/Ammonia/Water system for simulation.
3. Optimum steam to feed water ratio.

Pls. help.
many thanks

If you are using HYSYS, Sour PR fluid package is made for such applications.
Point No.2 - I am not sure if I understand you; you should be having feed analyses already with you. These are the "amounts of NH3/H2S" you are speaking about. Product spec is your target.
Steam to feed ratio depends on feed condition, product specs, and tower operating pressure - including the configuration which we don't know.

if you use Pro II its sour property package.

if you have it, the electrolight package in both Hysys and pro II could also be used. not very user friendly package to deal with thou.

what are you after, just H2S / NH3 ? or desolved hydrocarbons ? salts ? phenols ...?

you need to find your effleunt water specs and work back wards for best steam ratio.

first do your base case model to check

cheers,

Zauberberg,

1. Thanks for the property package info.
2. I have the feed , product and other stream analysis. I was referring to any values for binary interaction coefficients for Nh3/H2S/water system.( if required for the property package)


Thanks Again
