The rotary separator turbine (RST) is a machine that produces power from the expansion of a two-phase working fluid and discharges separate streams of liquid and vapor. EPRI has supported the evaluation and development of the RST in order to enchance the performance of direct-flash geothermal power systems. The EPRI project confirmed that an RST upstream of a steam turbine can increase the power output from a given flow of geothermal liquid by 20%. This report describes the concept, the 20-kWe experimental RST, the field test results from three sites where the 20-kWe unit was operated, the 1.6-MWe commercial prototype RST, the field test results from 4000 hours of operation of the 1.6-MWe RST, the first commercial RST power system designs and orders, and the application of the RST to high-temperature geothermal resources. Both commercial designs use the same standardized RST to develop 20% extra power output from the liquid discharged from a conventional steam separator, resulting in a 7% increase in total power output from the complete double-flash configuration.
