Environmental and cost pressures are prompting the gas industry to evaluate and try new techniques, such as liquid redox and scavengers, for treating natural gas containing small amounts of sulfur. The Gas Research Institute (GRI) sponsors an on-going program designed to help the industry evaluate available technology options and to develop new approaches. Since 1985, GRI has researched the application of liquid redox sulfur recovery technologies for direct treatment of sour natural gas at pipeline pressure, and in the last 2 years has expanded the research into scavenging-type processes. Sulfur exists in natural gas primarily as H[sub 2]S, an acutely toxic compound which is a health hazard and corrodes pipelines. The typical pipeline specification for H[sub 2]S is 0.25 grains/100 scf (about 4 ppmv). The paper discusses liquid redox processes, including the Stretford process, the SulFerox process, and the ARI-LO-CAT 2 process. The paper also discusses other processes, H[sub 2]S scavenging, technical evaluations, lab studies, field evaluations, and GRI basic research.
