Use of added water to achieve 100 % injection weight in geothermal operations

摘要

Geothermal brines are extracted from the earth, flashed and the remaining liquids are injected back into the earth. Although it would be advantageous for resource maintenance to inject the same amount of liquid as extracted, addition of liquid causes massive system upsets that prevent such addition. River or other similar surface waters can now be added to the brine stream created when extracting power from a geothermal source, after adding a crystal structure modifier to the brine stream. In operations where the brine stream is returned to the earth, the weight rate of the brine injected into the earth is brought to at least 90% what it was when extracted from the ground.
