FORMULATION FOR HYDROGEN SULPHIDE SCAVENGING FROM HYDROCARBON STREAMS AND USE THEREOF
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.
