ABSTRACT:
Steam from a geothermal source is usually contaminated with gaseous impurities including, inter alia, one or more substances comprising boron, arsenic and mercury. Such contaminants are detrimental to the equipment utilizing the steam as an energy source and also result in environmental pollution. Herein, a flow of geothermal steam at elevated temperature and superatmospheric pressure is processed upstream of said equipment by contacting the steam with an aqueous liquid whereby said impurities are extracted from the steam and transferred to the aqueous liquid while maintaining the steam at substantially said elevated temperature and pressure.
