METHOD FOR SCAVENGING MERCAPTANS IN A HYDROCARBON FLUID
The present invention relates to a method for scavenging mercaptans in a hydrocarbon fluid, comprising contacting the hydrocarbon fluid with an aqueous scavenging composition comprising an alcohol, an aqueous alkaline reagent and an effective scavenging amount of a phthalocyanine catalyst comprising disulfoacid of cobalt dichlorodihydroxyphthalocyanine mixed with disodium sulfate and potassium bromide, wherein the ratio of alkaline reagent to ethanol, by mass, is from 1:3 to 1:4; and the phthalocyanine catalyst is dissolved in ethanol in an amount of 1.0 to 1.5 mg/l.

PROCESS FOR PREPARING A SWEETENED HYDROCARBON LIQUID COMPOSITION WITH REDUCED TENDENCY TO FORM GUMS, A SCAVENGER COMPOSITION FOR USE IN SAID PROCESS, AND THE SWEETENED HYDROCARBON LIQUID COMPOSITION WITH REDUCED TENDENCY TO FORM GUMS SO PREPARED
The invention provides a process for preparing a sweetened hydrocarbon liquid composition with reduced tendency to form gums from a sour hydrocarbon liquid composition containing mercaptans and with an olefin content of 5 vol.% or more, by reacting the mercaptans in the sour hydrocarbon liquid composition into disulfides with an oxidizing agent in the presence of a scavenger composition comprising a cobalt complex as catalyst and a strong base, wherein the strong base consists of KOH. Also provided is a scavenger composition comprising the catalyst and the base that may be used in the process of the invention, and a sweetened hydrocarbon liquid composition with reduced tendency to form gums.
