Technology developments for lowering gas treating and sulfur recovery costs for Permian basin gas have been underway for several years by GRI (formerly Gas Research Institute) and other technology development organizations. Several of these technologies are now nearing the point where commercial applications should be evaluated since significant cost savings and operational simplifications could be achieved by early adopters. After a cursory review of current technology in gas treating and sulfur recovery, this paper summarizes applicable new technology in this area developed by the author's company and others including advances in H2S scavenging, small-scale sulfur recovery up to 15-20 TPD and large-scale gas treating for high acid gas concentration applications.
