Title: Status of the EIC process for hydrogen sulfide abatement

Conference · · Trans. - Geotherm. Resour. Counc.; (United States)
OSTI ID:6167224

Development of effective, economic control techniques for hydrogen sulfide emissions would remove a major environmental impediment to the future development of geothermal resources both in the United States and abroad. In a five-year development program, EIC Corporation has verified the process concept in laboratory and field tests, and designed, built and tested an integrated, one-tenth commercial scale pilot plant at The Geysers. The process, designated CUPROSUL, is based on a recycled copper salt scrub solution with the sulfur being rejected in the form of ammonium sulfate. The six month pilot plant test demonstrated the ability of the CUPROSUL process to deal with varying steam inputs, to average high degrees (97%) of hydrogen sulfide removal efficiency, to remove ammonia, boric acid and other contaminants, and to operate in a continuous manner. The process engineering design for commercial scale is complete for continuous, instrumented operation at a geothermal power generation site.
