Abstract
The Coury Process, a heat exchanger process for removing hydrogen sulfide from geothermal steam upstream of a power plant turbine, is presently being evaluated by Coury and Associates and Electric Power Research Institute (EPRI). The process utilizes a heat exchanger to condense and reevaporte geothermal steam, thus allowing the removal of non-condensable gases, including H2S, in a concentrated vent stream. Small scale field tests have been completed showing high removal rates of H2S and other non-condensable. Studies have been completed evaluating predicted costs and performance of various configuration and applications.
