Abstract
A new alkaline absorbent solution containing a tertiary amino azabicyclic alcohol in combination with its salt with a strong acid and/or in combination with a severely-hindered aminoacid is provided. A process for the removal of H.sub.2 S from fluid mixtures using this absorbent solution to produce a very low level of H.sub.2 S in the treated fluid is also provided. The process is also suitable for the selective removal of H.sub.2 S from fluid mixtures comprising H.sub.2 S and CO.sub.2. Use of the above absorbent solution leads to higher selectivity for H.sub.2 S without damaging capacity than observed when the tertiary amino azabicyclic alcohol is used alone without additive.
