Title
(EN) Regenerative method and composition for removing sulfides from gas streams
(ZH) 从气流中除去硫化物的组合物和再生方法
Abstract
(EN)
A method and composition for the removal of sulfides from gaseous streams. The method includes contacting the sulfide-containing gas stream with an aqueous scavenging mixture which includes a scavenging compound, an inorganic ion and an oxidation catalyst, regenerating at least a portion of the scavenging compound with an oxygen-containing gas and returning at least a portion of the aqueous scavenging mixture to the contacting zone. A scavenging compound consisting of the reaction product between an aldehyde and an amine is also provided.

(ZH)

一种从气流中除去硫化物的方法和组合物。该方法包括使含硫化物的气流与净化混合物水溶液接触,该净化混合物包括净化化合物,无机离子和氧化催化剂,用含氧气体再生至少一部分净化化合物,并将至少一部分净化混合物水溶液返回接触区。还提供了由醛与胺的反应产物组成的净化化合物。
