ABSTRACT:
The present invention generally provides sulfide scavenger solutions and processes that have high sulfide scavenging capacity, provide a reduction or elimination of solids formation and avoid the use of chemicals that pose environmental concerns. The invention utilizes a dialdehyde, preferably ethanedial, for the purpose of reacting with amines, amine carbonates, or other derivatives of amines that are liberated when certain scavenger solutions react with sulfides, including hydrogen sulfide and mercaptans. The scavenger solutions that have been discovered to liberate amines are those formed by a reaction between an amine and an aldehyde.
