    摘要： A new alkaline absorbent solution containing the additive of a severely-hindered amine salt and/or a severely-hindered aminoacid to a non-hindered amine such as N-methyldiethanolamine (MDEA) 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 than observed when MDEA is used alone without the additives.

    摘要翻译： 提供了将含有严重受阻胺盐和/或严重受阻氨基酸的添加剂添加到非受阻胺如N-甲基二乙醇胺（MDEA）的新型碱性吸收剂溶液。 还提供了使用该吸收剂溶液从流体混合物中除去H 2 S以在处理过的流体中产生非常低水平的H 2 S的方法。 该方法也适用于从包含H 2 S和CO 2的流体混合物中选择性除去H 2 S. 使用上述吸收剂溶液导致对于H 2 S的选择性高于当单独使用MDEA而没有添加剂时所观察到的选择性。

    摘要： The present invention provides a novel process for the removal and recovery of radionuclides from waste waters and process streams. The process of the present invention utilizes a combination of a supported liquid membrane (SLM) and a strip dispersion to improve extraction of the target species while increasing membrane stability and reducing processing costs. Additionally, the invention provides a family of new extractants, alkyl phenylphosphonic acids, for the removal and recovery of radionuclides and/or metals, including the use of the new extractants in the process. The new extractant selectively removes radionuclides and metals from the feed stream to provide a concentrated strip solution of the target species.

    摘要： 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.
