    Linear polarization measurements at high temperatures in hypersaline geothermal brines / ([Washington, D.C.]: Dept. of the Interior, Bureau of Mines, []), by Stephen D. Cramer and Paul B. Needham (page images at HathiTrust).   The broad color palette of the landscape is one of the most striking features of Dallol, as colors range from pale green to dark brown and reds, due to the combined action of the continuous discharge of oxygen-free Fe(II)-rich spring brines, the low solubility of oxygen in high temperature, hyperacidic brines, and hypersaline brines, and.

    Geothermal heat pumps have a lot of advantages over standard heating and/or cooling systems such as gas or oil boilers and cooling machines which render them sustainable [1,2].They allow large primary energy savings (e.g., [3,4]), strong reductions of CO 2 and other greenhouse gases emissions ([2,5] and references therein), and the use of energy stored in the subsurface (soil or groundwater).   It is highly mobile in hydrothermal systems, occurring in high concentrations in geothermal waters, with values up to 59 ppm Mn recorded in Mid Oceanic Ridge fluids with Cl concentrations close to that of seawater (∼ m Cl; James et al., ) and values up to ppm in hypersaline brines (>5 m Cl; Salton Sea, McKibben and Williams, ).

To investigate the relatively high electric resistivity in these hydrothermally productive fault zones, clay mineralogy was investigated at Coñaripe, together with a hydrothermal alteration reference of the El Toro high‐enthalpy geothermal field. A high fluid temperature at the Coñaripe spring (about 70 °C) and high reservoir temperature.

1 at the Salton Sea Known Geothermal Resources Area, Imperial Valley, Calif. The corrosive potential of the geothermal brines acting on metals mainly depends on chemical key species, such as hydrogen ion, halogenides, and dissolved gases at high temperature and pressure (Kaya and Hoshan, ).

Deep reservoir waters from the Upper Rhine graben are characterized by a high mineralization, mainly by NaCl. S.D. Cramer, P.B. Needham, Linear Polarization Measurements at High Temperatures in Hypersaline Geothermal Brines, Bureau of Mines Report of Investigations, It would appear that the use of linear polarization measurements can supply valuable information regarding: (1.) Studies of the effect of environment variables on corrosion rate.

These include changes in composition, velocity, and temperature, (2.) Evaluations of inhibitors in controlling corrosion, (3.). The Bureau of Mines conducted a series of in situ linear polarization measurements in high-temperature, high-pressure hypersaline geothermal brines at the Bureau of Mines Geothermal.

found that anodic polarization yielded corrosion rates about times larger than cathodic polarization. This was attributed to the rapid formation of a silica-rich scale on structures exposed to the brine at temperatures.

In this work, a CoCrFeNiMo high-entropy alloy (HEA) material was prepared by the vacuum arc melting (VAM) method and used for electro-spark deposition (ESD). The purpose of this study was to investigate the phase evolution and microstructure of the CoCrFeNiMo HEA as as-cast and electro-spark-deposited (ESD) coating to assess its suitability for corrosvie environments encountered in geothermal.
