从流体流中除去硫化氢
摘要：
用含有正铁螯合物和含有磺基，羧基或它们的混合物的水溶液作为一种阻催化剂可以达到基本上完全除去在酸气流或地热流中的硫化氢。在这过程中正铁螯合物还原为亚铁螯合物，并通过含有气流的氧气再生为正铁螯合物。本发明的聚合催化剂在铁的0.005至0.4浓度下抑制了氧化及螯合剂的损耗。
摘要（英）：

H2S is removed from a fluid stream by contacting the stream with an aqueous solution having at least two components: an effective amount of an iron (III) chelate to oxidize H2S to sulfur and, an amount of a water soluble anionic polymer containing sulfonic acid groups, carboxyl groups or mixtures thereof which is effective to stabilize the chelate. During the removal process the iron chelate is reduced to iron(II) chelate, and sulfur particles are produced.
