Abstract: A process for removing acid gases from a hydrocarbonaceous fluid stream or an oxygen-comprising fluid stream in which the fluid stream is contacted with an aqueous solution which is essentially free from inorganic basic salts and comprises (i) at least one amine and (ii) at least one metal salt of an aminocarboxylic acid and/or an aminosulfonic acid. Conjoint use of the aminocarboxylic and/or aminosulfonic salt reduces the coabsorption of hydrocarbons or oxygen without significantly impairing the absorption rate at which acid gases are absorbed, without significantly reducing the absorption capacity of the solution for acid gases, and without significantly increasing the energy demand required for regeneration.
Abstract translation: 一种从烃流体流或含氧流体物流中除去酸性气体的方法，其中流体物流与基本上不含无机碱式盐的水溶液接触，并且包含（i）至少一种胺和（ii） 至少一种氨基羧酸和/或氨基磺酸的金属盐。 氨基羧酸和/或氨基磺酸盐的联合使用可以减少碳氢化合物或氧气的共吸收，而不会明显削弱吸收酸性气体的吸收速率，而不会显着降低酸性气体溶液的吸收能力，而不会显着增加能源需求 需要再生。
