SOLUTIONS and TOOLS – introduction
A number of tools are considered suitable for evaluating plant performance and pinpointing possible solutions to specific operational challenges. Hence, information about chemical calculations, potential solutions to operational problems, economics and best practice procedures are discussed in this section. We also elaborate on the lessons learned from scaling and corrosion issues.
Chemical calculations – Saturation Index (SI)
The Saturation Index (SI) is a useful quantity to determine whether the geothermal water is saturated, undersaturated, or supersaturated with respect to the given mineral. The use of saturation index calculations in evaluating plant performance is discussed (next level text box).
Suggested solutions to operational challenges (including lessons learned)
A specific table lists common problems linked to geothermal operations and various solutions are suggested. Geological and geochemical causes of typical problems are unraveled and described in a text section. Focus is on how to handle and mitigate problems. In addition, the text focuses on new methods developed through the PERFORM study work. Reference is made to the ‘Solutions – table and text’ section, but also information given in the ‘CHALLENGES’ section should be consulted.
WORK IN PROGRESS. The economic performance of a doublet will be discussed.? Dutch and Danish site selected (see next level text box).
Best practice manual
WORK IN PROGRESS. A best practice manual will be prepared. Troels from FT (and TNO?) is developing technical guidelines. Operational advice and guidance will be provided. Description of best practice procedures. The outline of the toolbox is in progress (see next level text box).
