OSTI ID:20002767
Initial field tests have been completed for a Non-Condensable Gas (NCG) turbocompressor for geothermal power plants. It provides alternate technology to steam-jet ejectors and liquid-ring vacuum pumps that are currently used for NCG removal. It incorporates a number of innovative design features to enhance reliability, reduce steam consumption and reduce O and M costs. During initial field tests, the turbocompressor has been on-line for more than 8,000 hours as a third stage compressor at The Geysers Unit 11 Power Plant. Test data indicates its overall efficiency is about 25% higher than a liquid-ring vacuum pump, and 250% higher than a steam-jet ejector when operating with inlet pressures of 12.2 in-Hg and flow rates over 20,000 lbm/hr.
