A method has been developed for reducing the content of hydrogen sulphide in hydrocarbon streams. The method involves contacting a "sour" gas or fluid with a chemical formulation consisting of triethylene glycol and the reaction products of an amine and an aldehyde. The use of this method and chemical formulations produce spent products consisting of a single phase; thus alleviating problems associated with the deposition of dithiazine solids normally associated with triazine based scavengers. The method is especially useful for alleviating high temperature-induced dithiazine solids.
L'invention concerne un procédé destiné à réduire la teneur en sulfure d'hydrogène de courants d'hydrocarbures. Le procédé comprend la mise en contact d'un gaz ou fluide acide avec une formulation chimique constituée de triéthylène glycol et les produits de réaction d'une amine et d'un aldéhyde. L'utilisation de ce procédé et de ces formulations chimiques permet d'obtenir des produits usés constitués d'une seule phase, ce qui atténue ainsi les problèmes liés au dépôt de dithiazine solide normalement associés aux agents d'épuration à base de triazine.
