Agradecimiento
The authors gratefully acknowledge research funding by BMBF Client II for the BrineMine Project (Federal Ministry of Education and Research, FKZ: 033R190B). We thank Prof. Dr. J. Kolb and Dr. E. Eiche of the department of Geochemistry & Economic Geology (Karlsruhe Institute of Technology, Division of Applied Geosciences) for the support in developing the measurement strategy and the access to laboratories and equipment, as well as for fruitful discussions. The team of Pfalzwerke geofuture GmbH is thanked for enabling the prototype implementation at the powerplant Insheim and the pleasant cooperation during sampling. Further, we thank Transmark Renewables for the productive discussions and for enabling a joint sampling campaign. Finally, we appreciate the support of the Chilean ANID-Fondap program (projects 15090013 and 15200001).
strategic goals set by the German government. It is known that the highly mineralized thermal waters, which are circulated during the production of geothermal energy, sometimes have significant enrichments of economically strategic elements such as lithium, rubidium, antimony, tungsten, etc. [1, 2]. The BrineMine project aims to describe, qualitatively and quantitatively, the occurrence of these chemical elements in geothermal waters in Chile against the background of raw material extraction. The extraction of mineral raw materials from thermal waters is still challenging in terms of the process technology, but new sustainable methods are preparing the path to an economical production as an alternative to conventional extractive mining. An important milestone is the development of a large-scale prototype enabling effective precipitation and enrichment of selected raw materials from geothermal brines. The process used in the BrineMine project for the enrichment of the target substance is based on reverse osmosis and membrane distillation. It is driven by geothermal heat securing energy-neutrality and reduced greenhouse gas emissions. To ensure the longevity of the plant, an effective configuration of fluid pre-treatment and membrane modules is crucial. Due to overall high salt concentrations, selective separation of scale-forming minerals is required in a pre-treatment stage to avoid scaling or membrane fouling in the later process steps. The focus is on controlling silicate precipitation, which can be expected due to the change in temperature and pressure conditions. In laboratory and pilot plant tests, effective methods have been identified that allow instantaneous precipitation of up to 98% of the initial silica concentration. The application of the developed prototype takes place in two steps, first in an operating geothermal power plant in the Upper Rhine Valley in Germany and afterwards in Chile. The test location in Chile is selected according to the results of hydrogeochemical exploration campaigns supported by geophysical methods to determine the size of the subsurface reservoir and thus the economic viability. The BrineMine project is a 3-year research project funded by the German Federal Ministry of Education and Research. The project is realized as a bi-national research project between German and Chilean research and industrial partners. The project structure features two focal points: 1) Determination of the economic potential of thermal waters as a raw material resource and 2) Pre-treatment of thermal waters prior to raw material extraction. The Fraunhofer Institute ISE (Institute for Solar Energy Systems) leads the international consortium in close cooperation with the Karlsruhe Institute of Technology (KIT) and the Andean Geothermal Centre of Excellence (CEGA) at the Universidad de Chile. Further collaborates are the compa- nies SolarSpring membrane solutions and Geothermie Neubrandenburg (GTN). Further Chilean partners are CSET, GTN Latin America and Transmark Renewables. The comprehensive expertise of the consortium is required to deal with the multiple targets of the BrineMine Project. From a geological perspective, the purpose is to gain a better understanding of the resource potential from geothermal wells in Chile, as well as to carry out a large-scale exploration campaign to find appropriate locations for a prototype implementation. The project’s engineering part focuses on the design, production and installation of the prototype.
