Abstract
Kawerau and Nga Awa Purua Geothermal Power Plants have the largest capacity double flash and triple flash steam separation systems respectively, in the world.
This paper describes the system configuration selections, operations and commissioning experiences of low pressure (LP) brine reinjection systems utilizing two stage brine reinjection pumps to control LP separator brine level while achieving full brine reinjection under several operating scenarios.
