Inhibiting scale precipitation from high temperature brine

摘要

A method for inhibiting the precipitation of a scale, such as an iron silicate scale, from a hot aqueous brine solution, such as a geothermal brine, during production and handling of the brine wherein there is injected into the brine a brine-soluble acid in an amount sufficient to lower the pH of the brine from 0.1 to 0.3 pH units.
