Described are compositions comprising a reaction product of an amino alcohol and an aldehyde and a reaction product of a monohydric or polyhydric alcohol, an aldehyde and a nitrogen-containing compound. In addition, processes for removing sulfur compounds from process streams using such compositions are described, as well as such processes in which the process stream is contacted independently with a reaction product of an amino alcohol and an aldehyde and a reaction product of a monohydric or polyhydric alcohol, an aldehyde and a nitrogen-containing compound. Further described is the use of such compositions to remove sulfur compounds from process streams and the use of a reaction product of an amino alcohol and an aldehyde and a reaction product of a monohydric or polyhydric alcohol, an aldehyde and a nitrogen-containing compound to remove sulfur compounds from process streams. L'invention concerne des compositions qui comprennent un produit de réaction d'un aminoalcool et d'un aldéhyde et un produit de réaction d'un alcool monovalent ou polyvalent, d'un aldéhyde et d'un composé azoté. L'invention concerne également des procédés d'élimination de composés soufrés à partir de flux de traitement à l'aide de telles compositions et un procédé dans lequel le flux de traitement est mis en contact avec un produit de réaction d'un aminoalcool et d'un aldéhyde et un produit de réaction d'un alcool monovalent ou polyvalent, d'un aldéhyde et d'un composé azoté, indépendamment l'un de l'autre. En outre, l'invention concerne l'utilisation de telles compositions pour éliminer des composés soufrés à partir de flux de traitement et l'utilisation d'un produit de réaction d'un aminoalcool et d'un aldéhyde et d'un produit de réaction d'un alcool monovalent ou polyvalent, d'un aldéhyde et d'un composé azoté pour éliminer les composés soufrés de flux de traitement.
