Abstract
Kawerau geothermal field has relatively high level of non condensable gas (NCG) content. The paper describes the experience of engineering, procuring and commissioning of 3 trains of the hybrid type NCG Extraction System by Fuji Electric Systems (FES).The hybrid Gas Extraction System (GES) at Kawerau Geothermal project, which consist of 2 stages of steam jet ejector and liquid ring vacuum pump, is one of the largest of its type in geothermal use in the world. This paper also reports the result of GES performance tests at both shop and site.
