Metal carboxylate salts as H2S scavengers in mixed production or dry gas or wet gas systems

摘要

A transition metal carboxylate scavenger may be used to scavenge contaminants from systems from mixed production and/or gas, either dry or wet hydrocarbon gas. The contaminants scavenged or otherwise removed may include, but are not necessarily limited to, H2S, mercaptans, sulfides, and combinations thereof. Suitable transition metal carboxylates in the scavenger include, but are not limited to, zinc octoate, zinc dodecanoate, zinc naphthenate, and combinations thereof.

主权项

1. A method for at least partially scavenging a contaminant from a system selected from the group consisting of wet hydrocarbon gas, and dry hydrocarbon gas, the method comprising:
contacting the system with a transition metal carboxylate scavenger in an effective amount to at least partially scavenge a contaminant from the system, where the contaminant is selected from the group consisting of H2S, a mercaptan, a sulfide and combinations thereof, where a carboxylic acid complexed with the transition metal has 8 to 25 carbon atoms; and at least partially scavenging the contaminant from the system.
