US Patent:

58207660, Oct 13, 1998
Filed:

Apr 23, 1997
Appl. No.:

8/842296
Inventors:

Diane Gevertz - San Diego CA
Gary E. Jenneman - Bartlesville OK
Assignee:

Phillips Petroleum Company - Bartlesville OK
International Classification:

C02F 176
US Classification:

210753
Abstract:

A composition and a process for substantially reducing or removing sulfide from a sulfide-containing fluid are disclosed. The composition comprises, or is prepared by combining components comprising, a sulfide-containing fluid and a sulfide-scavenging amount of a sulfide scavenger selected from the group consisting of bromates, iodates, and combinations of two or more thereof. The process comprises contacting a sulfide-containing fluid with a sulfide-scavenging amount of a sulfide scavenger under a condition sufficient to substantially reduce the sulfide concentration in the fluid.
