Abstract
The emissions of hydrogen sulfide during the production of natural gas, oil or geothermal fluids from subterranean formations and the subsequent processing of these fluids is reduced by converting the hydrogen sulfide into a hydrogen halide or a halogen acid and then using the hydrogen halide or halogen acid for scale control and/or well acidizing. In a preferred embodiment, hydrogen sulfide produced with geothermal fluids is converted into hydrochloric acid, which is then used to reduce pH and control scale formation during the extraction of energy from geothermal fluids in a geothermal power plant.
