<p>A multi-component scavenging system containing at least one ester and at least one electron-deficient organic compound, together with or without one or more optional components such as an aldehyde having from 4 to 20 carbon atoms, a ketone having from 4 to 20 carbon atoms, an ether, a solvent, an alkali metal salt of an alkyl or dialkyl phenol, an epoxide, an alkyl anhydride, and mixtures thereof, may be used to scavenge contaminants from hydrocarbon and/or aqueous streams. The contaminants scavenged or otherwise removed may include, but are not necessarily limited to, ammonia, primary amines, secondary or tertiary amines, H2S, mercaptans, sulfide cyanides, and combinations thereof.</p> |
