  • Patent number: 4462905
    Abstract: When Geothermal water, obtained from natural sources, delivers heat to energy conversion equipment or to heat transfer surfaces, the resulting effluents are supersaturated with amorphous silica. This invention relates to passing such effluents through a fluidized particle bed in which the silica deposits on the bed particles. The coated particles are removed from the system, the coatings removed and the particles are recycled to the fluidized bed.
