Title
(EN) HYDROGEN SULFIDE SCAVENGING PROCESS
(FR) PROCEDE D'EPURATION DU SULFURE D'HYDROGENE
Abstract
(EN)
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 a dialdehyde having two carbonyl groups; and an alkanolamine having at least one hydrogen atom bonded directly to a nitrogen atom. The amounts of dialdehyde and alkanolamine provide between about 1.5 and about 3 equivalents of hydrogen atoms bonded directly to a nitrogen atom in the alkanolamine for every equivalent of carbonyl groups in the dialdehyde. The reaction product thus formed is substantially free of triazines.
(FR)
On réduit les taux de sulfure d'hydrogène et de sulfures organiques présents dans des courants d'hydrocarbures gazeux ou liquides ou dans des mélanges de ceux-ci en mettant en contact les courants avec une composition comprenant le produit de réaction d'un dialdéhyde possédant deux groupes carbonyle, et d'une alcanolamine possédant au moins un atome d'hydrogène lié directement à un atome d'azote. Les quantités de dialdéhyde et d'alcanolamine fournissent entre environ 1,5 et environ 3 équivalents d'atomes d'hydrogène liés directement à un atome d'azote dans l'alcanolamine pour tout équivalent de groupes carbonyle dans le dialdéhyde. Le produit de réaction ainsi obtenu est pratiquement exempt de triazines.
