Abstract
Sulfur-containing acid is produced at a geothermal energy source from hydrogen sulfide produced as part of a geothermal process and introduced into aqueous liquid brine to lower the pH of the liquid brine. The lowered pH of the brine inhibits silica, metal sulfide and/or calcite formation on the surfaces of geothermal energy processing equipment or in subterranean formations in which the brine is injected.
