Thermodynamics and kinetics of silica scaling

  title={Thermodynamics and kinetics of silica scaling},
  author={Kevin Brown},
Silica scaling is probably the principal factor limiting the extraction of energy from high temperature geothermal systems. Silica exists in a number of polymorphs from quartz through to opal A (or amorphous silica). The thermodynamics of the solubility of quartz and amorphous silica with variations in temperature, salt content, pH and pressure are discussed. However, in silica saturated geothermal brines, silica normally precipitates from oversaturated brines as a colloid. The colloid… CONTINUE READING
