    • A method is disclosed for polishing geothermal brines containing iron-rich silica scale and silica particles suspended therein while removing and recovering copper, silver and other precious metals dissolved therein. The method comprises passing brine having a pH just below about 5.0 through a conduit packed with a metal higher in the electromotive series than silver for a time sufficient for a substantial portion of the copper and silver therein to precipitate onto the packing. Preferably, the packing comprises coiled zinc-galvanized steel chicken wire mesh packed in a sufficient density to act as a filter for said suspended particles. Dissolving the packing in a suitable acid will leave a precious metal-rich residue behind for subsequent recovery. When the brine is treated in accordance with this method, the useful life of injection wells used to return cooled brine back to the geothermal field is extended by at least about 3 time as compared to that observed with untreated brine. Further the treated brine is less corrosive than it was before treatment.

    • A method of heating an aqueous fluid which can be, for example, water, in a dry geothermal reservoir formation penetrated by an injection well and a production well comprising injecting the said fluid into the formation via the injection well, forcing the fluid into the formation with simultaneous heating and finally recovering the heated fluid via the production well. Utilizing heat exchangers at the surface, the heated fluid may be employed to supply process heating requirements for steam making, preheating of refinery streams such as crude oil feed to distillation units, salt evaporation, etc. Alternatively, where the heated fluid recovered via the production well is steam, it can be employed directly, for example, in a turbine for power generation.

    • Apparatus is provided for treating a flow of hot, pressurized, hydrogen sulfide-containing geothermal steam, particularly a flow of high-energy, surplus steam substantially as produced from the ground. The apparatus comprises a first condenser in which most of the steam in the flow is condensed, and a first separator in which the steam condensate is separated from residual amounts of steam and non-condensable gases (including hydrogen sulfide). An after-cooler is provided for cooling the condensate to a disposal temperature of less than about 200.degree. F. before the condensate is discharged into a disposal well, the disposal temperature being such as to create a vacuum in the disposal well. A second condenser is provided in which is condensed a substantial amount of the steam in the mixture of residual steam and non-condensable gases, the condensate being separated from a mixture of residual steam and non-condensable gases in a second separator. Condensate from the second separator is combined with condensate from the after-cooler and is discharged therewith into the disposal well. The mixture of non-condensable gases and residual amounts of steam is also discharged from the second separator into the disposal well, being drawn thereinto by the vacuum in the well. A corresponding method is provided for treating a flow of geothermal steam so as to control hydrogen sulfide emissions therefrom.

    • Certain impure steams, especially those from geothermal sources, are contaminated with gaseous substances such as hydrogen sulfide, ammomia, carbon dioxide, substances comprising boron, arsenic and mercury, other gases, as well as finely divided particulate solid matter in a form resembling dust or smoke. These contaminants reduce the efficiency of the steam as a heat transfer fluid and are detrimental to equipment utilizing steam as an energy source. Furthermore, discharges from the utilization of such impure steams result in pollution of the environment or necessitate expensive requirements for limiting the same. The present invention describes apparatus wherein so contaminated steam is selectively processed at superatmospheric pressure for removing one or more of said contaminants and, after reduction of its energy content by pressure reduction and/or condensation of the steam, gases substantially free of hydrogen sulfide are discharged to the atmosphere. The apparatus includes means for contacting the impure steam with an aqueous liquid containing reactant capable of reacting with at least one of said contaminants in the steam, e.g. hydrogen sulfide, to form non-gaseous reaction products including solids, e.g. metal sulfides, and for separating and removing solids from the aqueous liquid phase. Means are also described for recycling untreacted reactant and/or for regeneration of reactant from metal sulfide, and for recovering byproducts from the reaction products. By use of the described apparatus, the utility of impure steam may be improved and pollution of the environment from emission of hydrogen sulfide and other contaminants may be avoided.
