Abstract
Sulfurous acid and/or sulfurous acid precursors, such as sulfur dioxide, are introduced into a hydrogen sulfide-containing geothermal brine or fluid prior to extracting energy from the resulting mixture by, e.g., passing the mixture through a flash vessel or a heat exchanger. The introduction of the sulfurous acid or its precursors into the geothermal brine or fluid inhibits scale formation and/or removes previously formed scale during processing of the brine or fluid.
