The selective removal of H.sub.2 S gas from a normally gaseous mixture containing H.sub.2 S and CO.sub.2 is accomplished by contacting the gaseous mixture with an absorbent solution comprising a diaminoether wherein at least one amino group is a tertiary amine whereby H.sub.2 S is selectively absorbed from the mixture.
从通常含有H.sub.2 S和CO.sub.2的混合气体中选择性地去除H.sub.2 S气体是通过将气体混合物与包含二
氨基醚的吸收溶液接触来实现的,其中至少一个
氨基是三级胺,从而选择性地吸收混合物中的H.sub.2 S。
