Abstract
A method and composition for reducing the levels of hydrogen sulphide and mercaptans in hydrocarbon streams. The method comprises contacting the gas stream with a composition comprising the reaction product of mixing monoethanolamine, diglycolamine and formaldehyde. The use of the method and composition alleviates problems associated with crystalline dithiazine depost build-up associated with the use of triazine based scavengers.
