吸收剂、用于制备吸收剂的方法以及用于从酸性气体中分离硫化氢的方法和设备
摘要：
本发明涉及一种包括溶解的氨基酸盐和溶解的金属的吸收剂。吸收剂在吸收器中与酸性气体形成接触。在吸收器中，H2S从气相转变为液相。此外，同样地根据接触时间从气体中吸收二氧化碳(CO2)。洗涤溶液从吸收器被引导至再生池。在再生池中，用空气、用氧气(O2)富集的空气或者用纯的O2吹扫溶液。通过在溶液中输送O2，已经含在溶液中的H2S在溶解的金属催化剂处反应。在再生之后，可能的固体物质被分离并且再生的洗涤溶液引回至吸收器。
摘要（英）：

The invention relates to an absorbent which comprises a dissolved amino acid salt and a dissolved metal. The absorbent is brought into contact with the acidic gas in an absorber. In the absorber, the H2S converts from the gas phase to the liquid phase. In addition, carbon dioxide (CO2) is likewise absorbed from the gas as a function of the contact time. The washing solution is passed from the absorber to a regeneration tank. In the regeneration tank, the solution is gassed with air, oxygen (O2)-enriched air or with pure O2. By introducing O2 into the solution, the H2S already present in the solution is reacted over the dissolved metal catalyst. After the regeneration, possible solids are separated off and the regenerated washing solution is returned to the absorber.
