Abstract
Spent geothermal fluid from a geothermal power plant comprises geothermal vapor in the form of steam and non-condensable gases, and geothermal liquid in the form of mineral-rich brines. A silencer, which receives the spent geothermal fluid, includes a chamber for receiving the spent fluid and which has a lower outlet from which the brine flows. The chamber has an upper outlet through which the geothermal vapor flows. A heat exchanger is connected to the upper outlet, the heat exchanger having a first portion for receiving the geothermal vapor and the second portion containing a working fluid that is vaporized by the heat contained in the geothermal vapor. As a result, the cooled geothermal vapor produces a low pH condensate and non-condensable gases in the first portion. The brines exiting the silencer through the lower outlet are combined with the low pH condensate and with the non-condensable gases to form waste fluid which may be disposed of by injection into a reinjection well.
