Analyses of mixed-hydrocarbon binary thermodynamic cycles for moderate-temperature geothermal resources using regeneration techniques

Description: Studies of basic binary geothermal cycles utilizing mixtures of hydrocarbons have shown better performance than for pure fluids for a moderate temperature (360/sup 0/F) resource. However, a loss is net geofluid effectiveness (watt-hours net plant output/1bm geofluid) results when the geofluid outlet temperature is limited to temperatures in excess of 160/sup 0/F to alleviate a silica precipitation problem. This study examined three working fluids consisting of binary mixtures of hydrocarbons to… more

Quick look report on the startup tests for the Raft River 5-MW(e) pilot geothermal power plant

Description: A preliminary analysis was made of the initial startup data taken between October 20 and November 2, 1981 for the 5 MW(e) Pilot Geothermal Power Plant located at the Raft River Site in southeast Idaho. This plant utilizes a dual-boiling isobutane binary cycle. Two test conditions were selected for analysis: (1) a thermal loop test with 94% of the design geofluid flow, and (2) a test at about three-fourths of the design geofluid flow in which one megawatt was generated from working-fluid flow th… more
