摘要：
The corrosion of iron and steel surfaces by an aqueous alkanolamine conditioning solution used to remove CO.sub.2 from a gas stream is effectively inhibited by a combination of a vanadium containing ion and a di- or triamine. A surprising fact is that some of the amine co-inhibitors have been identified by others in the art as promoting ferrous metal corrosion.
