[selimmm]

Hi everybody,
I've to design an H2S stripping column that uses lean gas from HP separator to sweeten sour oil
I've specifications flowrates and everything. I've to find the number of stages and column size.
How to do that, does this process have a name, does the GSPA M19 really help?
Thank you all

Hi mh_mahmoodieh,
I'm actually looking for a calculation procedure, a detailed one. GSPA didn't really help me.
I did simulation in HYSYS and it gave me 4 trays.
