Low viscosity metal-based hydrogen sulfide scavengers
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 and alkyl alcohols having from about 1 to about 4 carbons.
1. A method for treating fluids contaminated with hydrogen sulfide comprising introducing into the hydrogen sulfide contaminated fluid an additive for scavenging hydrogen sulfide from the hydrogen sulfide contaminated fluid, the additive comprising zinc octoate (1:2) and a viscosity improver comprising diethylene glycol mono-n-butyl ether.
2. The method of claim 1 wherein the zinc octoate is prepared using zinc powder or zinc oxide.
3. The method of claim 2 wherein the zinc octoate is prepared using ethyl hexanoic acid.
4. The method of claim 3 wherein the carboxylic acid used to prepare the zinc octoate is 2-ethyl hexanoic acid.
