| Abstract |
This paper presents the research made upon scaling problems which could appear at geothermal water utilization in western part of Romania. Emphasis was places on the geothermal fields of Bors and Ciumeghiu. Geothermal waters from two production wells were sampled during years and analyzed using standard methods. The chemical monitoring has given the chemical changes that may later lead to scaling. Bases on the chemical composition of these waters, by using a chemical computer program, were assessed in time the scaling depositions which could appear at geothermal utilization when the temperature decreases. Severs scaling problems have been encountered. Scaling monitoring device were installed into two wells for one year. The scale deposits were analyzed thermic differential and by X-ray diffraction. The experimental results were compared to those that were obtained by using the computer program. |
