Title:
GEOTHERMAL POWER GENERATION SYSTEM AND SILICA SCALE DEPOSITION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/070490
Kind Code:
A1
Abstract:
Provided is a geothermal power generation system with which it is possible to control silica scale deposition. This geothermal power generation system comprises: a production well; a steam-water separator which separates a geothermal fluid obtained from the production well into steam and hot water; a turbine which rotates by means of the steam separated in the steam-water separator; a reinjection well which returns the geothermal fluid which has passed through the steam-water separator and/or the turbine; a pH measurement system which measures the pH of an extracted portion of the hot water separated in the steam-water separator, and a first thermometer which measures the temperature of the extracted portion of hot water; an injection device which injects an alkaline agent into the geothermal fluid; a second thermometer which measures the temperature of the geothermal fluid at a pH estimation point selected from among an injection part for the alkaline agent, an outlet of the steam-water separator, and a reinjection well inlet; and a control device which controls the injection of the alkaline agent by the injection device on the basis of the measurement results from the pH measurement system, the first thermometer, and the second thermometer.
