The presence of noncondensible gases in the geothermal steam has a number of adverse effects on geothermal energy recovery. An upstream reboiler is used in geothermal power plants to remove hydrogen sulfide, other noncondensible gases and particulates from the steam upstream of the turbine. By condensing the geothermal steam and reboiling clean condensate, pure steam can be fed to the turbine. The objective of this study was to determine how the key measures of reboiler performance depend on independent operating parameters over a broad range of conditions. The chemical and thermal behavior of upstream reboilers are discussed. The Cerro Prieto geothermal field was selected as the test site for the reboiler unit. The test unit and test plan are described.
