  • Efficiency of a Biodegradable Antiscalant against Barite under Geothermal Plant Conditions

    In geothermal power plants, various types of scales can occur. Barite (BaSO4, barium sulfate) is the dominating mineral species of the scales in a region in middle Europe, acting as isolation material and leading to a reduction of the heat transfer and clogging of installations. Further, sulphide minerals like galena (PbS, lead sulfide) may be part of the scaling. As a ...
