Influence Of Brine Precipitates On Materials Performance In Geothermal Applications

Picture for Influence Of Brine Precipitates On Materials Performance In Geothermal Applications
Available for download

Since geothermal reservoirs are a feasible energy source to replace fossil fuel supply, many technologies have been developed to take advantage of geothermal energy. Nevertheless, due to the chemical composition of hydrothermal fluids and temperatures, service conditions in geothermal facilities are demanding in many cases in terms of corrosion. Therefore, materials selection based on preliminary material qualification is essential to guarantee a secure and reliable operation of the facilities.

Since geothermal wells are a feasible energy source to replace fossil fuel supply, many technologies have been developed to take advantage of geothermal energy. Nevertheless, service conditions in geothermal facilities are in many cases extreme in terms of corrosion due to the chemical composition of hydrothermal fluids and temperatures. Therefore, materials selection based on preliminary material qualification is essential to guarantee a secure and reliable operation of the facilities. During operation of a geothermal research facility in Groß Schönebeck copper and lead effects have been found downhole. Occurring mechanisms and measures to prevent precipitation or scaling needed to be investigated as well as potential influences of such precipitates on corrosion resistance of metallic materials used for equipment.

Weathering Of Industrial Coatings: Correlation Between Three Years Outdoor Florida Exposure And Four Accelerated Weathering Methods

Implementation of classification and certification programs for durable industrial and infrastructure maintenance coating systems is hindered by a lack of test protocols to reliably accelerate the aging process and estimate service lifetime. This gap in the industry also hurts development efforts to
reformulate or add new color choices to existing product lines. The first problem can be addressed by performing long-term weathering testing at outdoor exposure sites in places like south Florida and Arizona, but the need to wait 5 or 10 years or longer to confirm a classification or certify a product makes such schemes difficult to implement and ultimately reduces their value.

Carbon capture and storage (CCS) are technologies aimed at capturing CO2, followed by transportation to a storage site and injection into one of several types of stable geological formations, to trap and prevent its subsequent emission. Though CO2 transport and injection for Enhanced Oil Recovery (EOR) are known for over 40 years, new challenges arise when the CO2 source is anthropogenic, meaning with a human-cause origin and not natural (as in EOR). EU Directive 2009/31/EC states that CO2 streams from power stations or industrial plants "shall consist overwhelmingly of CO2" but may contain associated incidental substances (e.g., SOx, NOx, O2, H2S).

During operation of DC rail transit systems, DC current will follow the path of least resistance when returning to the Traction Power Substations (TPSS) to complete the electrical circuit. If the track-to-earth resistance (resistance between the train rails and surrounding soil) is not sufficient, current can leak off the LRT track system into the surrounding soil. Metallic facilities such as pipelines in the soil offer lower resistance paths for the current while returning to the TPSS.
