NH3 and H2s

[TomX]

Hello

Does anyone have experience with the following problem?

Im working in a petroleum refinery, and we are trying improve the sulfur recovery units trying to separate the h2s from the nh3 coming from the sour water stripping units (trying to concentrate the h2s composition over the nh3 in order to improve the SRU performance).
There is a way or technology that could help to do this?(like PSA unit that could separate the h2s from nh3, for example?)

Thank you very much...

The Chevron WWT process is available for licensing. It is a two-tower
(two-stage) sour water stripping system that removes the ammonia and the hydrogen sulfide separately.
