Process for selective removal of H2S from mixtures containing H2S and CO2 using di-severely sterically hindered secondary aminoethers

摘要

The selective removal of H2S gas from a normally gaseous mixture containing H2S and CO2 is accomplished by contacting the gaseous mixture with an absorbent solution comprising a di-secondary aminoether wherein each amino group has a severely sterically hindered secondary amino moiety whereby H2S is selectively absorbed from the mixture.
