Calcite- and silica-based scale deposits are a big challenge when utilizing geothermal energy for power generation. The effects of scaling are significant and often result in large reductions in power generation and significantly increased costs of operation.
Solenis understands just how critical scale control is to geothermal power generation and has developed a proprietary modeling tool to assist geothermal power producers in proactively managing scale and the resulting operational issues. The GeoSol performance modeling tool is a web-based application that allows users to assess the likelihood of mineral scale formation in geothermal production wells and surface equipment. Powering the GeoSol performance modeling tool is WATCH Version 2.4 (Iceland GeoSurvey, April 2010) software.
Based on brine and gas chemical analyses, the GeoSol performance modeling tool calculates the downhole chemical composition, pH and thermodynamic saturation indices of mineral scales. Solenis experts utilize the information provided by the modeling tool to advise plant personnel of the type of scale likely to form and where the scaling is likely to occur. Armed with this information, Solenis can recommend the most cost effective chemical mitigation strategy to proactively address scaling.
Benefits recorded from actual commercial applications using the modeling tool include:
- Improved scale control
- Reduced cleaning costs
- Reduced downtime
- Increased power generation
- Lower capital costs
