ABSTRACT:
The levels of hydrogen sulfide and organic sulfides present in gaseous or liquid hydrocarbon streams or mixtures thereof are reduced by contacting the streams with a composition comprising the reaction product of aminoethylpiperazine, an alkanolamine, an etheramine, a polyalkyleneamine, or a polyoxyalkyleneamine with a C1 to C4 aldehyde, including monoaldehydes and dialdehydes, such as ethandial. The solubility of polyamine/aldehyde reaction products is increased by the presence of an enchancing amine/aldehyde reaction product. The enhancing amines include alkanolamines, etheramines, and mixtures thereof.
