Claims20
Method of reducing the level of sulfide impurities present in a hydrocarbon or hydrocarbon substrate containing a sulfide comprising contacting the hydrocarbon or hydrocarbon substrate with potassium formate and a sulfide scavenger.
Method of reducing the level of sulfide impurities present in a hydrocarbon also containing water comprising (a) contacting said hydrocarbon with potassium formate to extract at least some of said sulfide impurities with at least some of said water from said hydrocarbon and (b) contacting said water with a sulfide scavenger.
A composition comprising a sulfide scavenger and potassium formate in a weight ratio of 1:9 to 9:1.
Method of scavenging a sulfhydryl compound from a hydrocarbon substrate containing a sulfhydryl compound or an aqueous substrate containing a sulfhydryl compound, comprising contacting said substrate with potassium formate and a sulfide scavenger, said sulfide scavenger comprising an amine/aldehyde condensate.
Method of removing a sulfide from an aqueous sulfide-containing substrate comprising contacting said sulfide-containing composition with potassium formate and a sulfide scavenger.
