I would be so pleased if you send me a relation (as graph or table) between MDEA concentration in lean amine stream

and H2S Concentration of inlet gas in contactor column.

You have 3 posts on here regarding gas sweetening. Wouldn't some of these questions be better directed at the Process Engineer that I hope is working with you?

I'm not aware of any such relationship though I'm not an amine expert. To my understanding, MDEA is typically operated at 50 wt%, 40% for liquid/liquid treating because of increasingly high HC losses in the MDEA at concentrations above 40 wt%.
