Abstract
In an absorption process in which an absorption medium is utilized to absorb H.sub.2 S from a feed gas containing H.sub.2 S, the flow rate of the lean absorption medium is manipulated so as to maintain the actual H.sub.2 S concentration in the product gas stream from the absorption process substantially equal to a desired value for the H.sub.2 S concentration. However, if the H.sub.2 S concentration in the rich absorption medium stream exceeds a high limit, the control of the lean absorption medium flow rate so as to maintain a desired H.sub.2 S concentration in the product gas stream is overridden until such time as the H.sub.2 S concentration in the rich absorption medium stream is below the high limit.
