Low viscosity metal-based hydrogen sulfide scavengers

Abstract

A composition useful for scavenging hydrogen sulfide by admixing metal carboxylates which have high viscosity due to polymerization and a viscosity improver selected from the group consisting of glycol ethers having from about 4 to about 10 carbons, alkyl alcohols having from about 1 to about 10 carbons, and combinations thereof.

What is claimed is: 
     
         1 . A composition useful for scavenging hydrogen sulfide comprising a zinc carboxylate and a viscosity improver selected from the group consisting of ethylene glycol monopropyl ether, ethylene glycol monoisopropyl ether, ethylene glycol monobutyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol mono-n-butyl ether, and combinations thereof. 
     
     
         2 . The composition of  claim 1  wherein the zinc carboxylate is prepared using a carboxylic acid selected from the group consisting of ethyl hexanoic acid, acetic acid, propionic acid, hexanoic acid, nonanoic acid, decanoic acid, neo-decanoic acid, naphthoic acid, linoleic acid, naphthenic acid, tall oil acid, oleic acid, 2-methyl valeric acid, and combination thereof. 
     
     
         3 . The composition of  claim 1  further comprising one or more alkyl alcohols having from about 1 to about 10 carbons. 
     
     
         4 . The composition of  claim 3  wherein the one or more alkyl alcohols is selected from the group consisting of methanol; butanol; ethanol; propanol; isopropanol; and combinations thereof.
