Fig. 7From: Scale-fragment formation impairing geothermal energy production: interacting H2S corrosion and CaCO3 crystal growthSchematic and stepwise (1–5) illustration of the principle mechanisms leading to scale-fragment development in pipes (vertical or horizontal) and finally resulting in heavy blockage of heat exchangers or other obstacles (e.g., filters). This conceptual model might also be applied in other cases of problematic scale-fragment evolutionBack to article page
