Abstract
The energy demand is increasing day by day. Therefore, the renewable and sustainable energy of geothermal power plants is very important. The biggest problems seen in geothermal power plants are sedimentation and scaling. The scaling occurs into the wells, pipelines and heat exchangers, etc. where the geothermal brine passes. Those locations where the elements and compounds in the geothermal brine precipitate under specific conditions, forms scales.
 Those scales caused decreased efficiency of energy production. During the process of energy production, the temperature drops inside heat exchangers and that causes the antimony (Sb) compounds got precipitated and caused scaling. Those scales negatively affect heat transfer and eventually cause less energy to be produced by causing blockage of the vaporizer, preheater, and filters. For this reason, stibnite scaling is a situation that should be taken into serious consideration. Until now, different methods have been developed against stibnite scalings.
 As of 2020, HYDRODIS® GE has been developed by the Bozzettto group, which stops the precipitation and cuts the operating costs. In this way, the antimony compounds where possibly creates scales got prevented and returned in the geothermal brine to the reservoir via reinjection wells by letting production continue without any energy loss.
Highlights
Geothermal wells are used to transfer the hot magma energy under the earth’s crust to underground water
The following data which obtained during the trial was performed by the XRF analysis made on the filters together with the physical observation of them
Scanning Electron Microscopy (SEM) analyzes of the samples obtained were carried out with the Fei Quanta 250 Feg and EdX analysis with the EDX Detector (Oxford Aztec) device
Summary
Geothermal wells are used to transfer the hot magma energy under the earth’s crust to underground water. Some important places with hot water and convection and upstream steam return are California, New Zealand, Italy, Turkey, Japan, and Iceland. Among these countries, Turkey has an important position. As a country with rich geothermal district heating, is used for greenhouse heating and spa centers with the production of both electricity (Baran vd., 2015). Alaşehir geothermal field is one of the high-temperature regions in the Gediz graben and is the region where the geothermal power plant in this study is located. Many geothermal areas in Turkey have are low to medium enthalpy fields, which are the most preferred systems for generating electricity in binary power plants (Baran vd., 2015)
