A program of laboratory and pilot plant tests, detailed process and project engineering work, and process engineering and economic evaluation studies has been carried out in support of the design of a test facility for demonstration of the copper sulfate process for the removal of hydrogen sulfide from geothermal steam at turbine upstream conditions. A demonstration plant has been designed which is capable of removing 99% of the H/sub 2/S, 90% of the NH/sub 3/, and significant amounts of H/sub 3/BO/sub 3/ and particulates from 100,000 lb/hr of geothermal steam of The Geysers composition. Criteria for the mechanical and process design of the scrubber have been confirmed in field tests of fifty hours duration on an eight-inch diameter scrubber at PG and E's Unit No. 7, The Geysers. The background of the problem and the technical approach to its solution, the scope and results of the first-phase laboratory testing, the scope and results of the experimental and analytical studies carried out in the second phase, and a description of the configuration of the demonstration plant and the test plan for its operation are summarized.
