The Kinetics of Quartz Dissolution and Precipitation

OSTI ID:886868
Silica precipitation in geothermal power plants and in reservoir formations is considered to be a potential problem area in the successful development of geothermal power from liquid dominated resources. In order to gain insight into the significance of this problem and to estimate the rates of precipitation of silica under varying conditions, a literature review and evaluation was made. Data on the kinetics of quartz dissolution and precipitation in water was fitted to an expression derived from absolute rate theory, assuming that the mechanism could be represented by the equation: SiO{sub 2} + 2H{sub 2}O = Si(OH){sub 4}.
