ABSTRACT:
A corrosive acid sulfate geothermal brine is mixed with a near neutral, bicarbonate geothermal brine containing above about 300 ppm silica to produce a relatively benign mixed brine of pH from about 4.5 to about 6.5 having reduced corrosivity as compared to the acid sulfate brine and a reduced tendency as compared to the near neutral, bicarbonate brine for depositing silica in equipment during brine processing.
