Definitions

• the present invention relates to a system and method that simulates the preheater unit in geothermal power plants and collects detailed data for monitoring scale formations (deposit, corrosion, pollution).
• Geothermal means ground temperature.
• the ground temperature heats the fluids (liquids and gases) trapped in the rocks or circulating with different ways. These heated liquids or gases are called geothermal fluids.
• the energy obtained from geothermal fluids and hot-dry rocks is called geothermal energy.
• Steam and liquid fluid with high enthalpy extracted by drilling underground boreholes so as to generate electrical energy in geothermal power plants are given by means of heat exchangers or directly to the steam turbines and thus electrical energy is obtained. While the fluid is stable within the reservoir and under pressure, the gases contained in it are dissolved in the liquid. After the production boreholes are drilled, the gases contained in the fluid brought to the surface through these boreholes are released.
• the invention is a method and system for monitoring scale formation in geothermal plants which exceeds the state of the art, eliminates the disadvantages and has some additional features.
• the aim of the invention is to simulate the preheater unit in geothermal facilities and to present a system integrated into the geothermal facility and an observation method provided by the system so as to observe scale formations.
• Another aim of the invention is to present a monitoring system and method that detects silica-stibnite and silica-iron-based scale formations.
• Another aim of the invention is to present a scale formation monitoring system and method thereof which collects inlet-outlet pressure and temperature data, differential pressure data and flow rate data by integrating into the geothermal facility.
• Another aim of the invention is to present a scale formation monitoring system and a method thereof which allows the analysis to be made by transferring the collected data to digital media with USB sticks and/or wired and wireless data transmission methods.
• Another aim of the invention is to present a scale formation monitoring system and a method thereof which consists of two lines so as to allow tests, experiments and observations to be made independently of the central system.
• Another aim of the invention is to present a scale formation monitoring system and a method thereof which allows simultaneous testing and monitoring of different products and/or different dosages and/or different reinjection temperatures.
• Figure- 1 is a representative view of the inventive scale formation monitoring system.
• First line 111 First line inlet pressure sensor
• inventive scale formation monitoring system (100) system and method is described by means of examples only for clarifying the subject matter such that no limiting effect is created.
• a system and method that simulates the preheater unit (220) in geothermal power plants and collects detailed data for monitoring scale formations (deposit, corrosion, pollution) is disclosed.
• FIG. 1 a representative view of the inventive scale formation monitoring system (100) is given.
• the scale formation monitoring system (100) is integrated into the connection line (230) between the evaporator unit (210) and the preheater unit (220) located on the plant platform (200) of the geothermal plant, simulating the preheater unit (220).
• Possible scale formations can be detected by simulating the preheater unit (220).
• inlet and outlet temperature values, inlet and outlet pressure values, differential pressure values and water flow rate values are detected by sensors and related equipment via the scale formation monitoring system (100) and these detected values are transferred to digital media and analyzed.
• the methods desired to be applied to reduce the scale formation are tested on the simulation platform provided with the scale formation monitoring system (100), instead of being applied to the entire geothermal plant platform (200). If the results of the tests are positive, the desired methods can be applied to the entire geothermal plant platform.
• Two lines are used in the inventive scale formation monitoring system (100). These lines are also given in figure 1 as the first line (110) and the second line (120). While collecting current data (temperature, pressure, differential pressure and flow rate) of the plant platform (200) in one of these lines (such as first line (110)), current data (temperature, pressure, differential pressure and flow rate) for an alternative application (which may be an alternative method to be tested to remove scale formation) and/or current data (temperature, pressure, differential pressure and flow rate) for a different plant platform (200) are collected over the second line (120).
• Two different applications can be compared simultaneously with the use of the first line (110) and the second line (120) in the invention, the instant data of the plant platform (200) and the instant data of an alternative method can be compared simultaneously and the current data of two different plant platforms (200) can be collected simultaneously.
• the inlet-outlet temperature and pressure data of the geo-fluid circulating in the first line (110) and the second line (120), the differential pressure data showing the pressure change between any two points, and the flow rate data of the geo-fluid are instantly collected and transmitted to the control unit (130).
• the data collected in the control unit (130) can be analyzed by transferring the same to a server in the digital environment via any of the USB memory and/or wired connection and/or wireless connection methods.
• it can be determined whether scale formation is observed or not and the causes of scaling (silica-stibnite, silica-iron) can be determined with the samples to be taken from the removable observation points on the system.
• Temperature data The inlet temperature of the scale formation in the monitoring system lines (110, 120) is assumed to be substantially a constant value under operating conditions. On the other hand, it is expected that the outlet temperature in the lines (110, 120) will increase proportionally and due to scaling. For this reason, temperature data is used for comparative evaluation of the rate and rate of scaling (silica, stibnite, iron development, contamination).
• Flow rate data As the scale formation in the lines (110, 120) of the monitoring system (100), which is integrated cleanly to the plant platform (200) increases at the beginning of the application, the flow rate (flow rate) gradually decreases due to the resistance against the flow. For this reason, the flow rate data is used for comparison in determining the scale formation.
• the lines (110, 120) of the inventive scale formation monitoring system (100) there are numerous elements so as to collect temperature, pressure and flow rate data.
• first line inlet temperature sensor (112) which measures the inlet temperature value of the geo-fluid
• first line outlet temperature sensor (115) which measures the outlet temperature value of the geo-fluid in the first line (110).
• a first line differential pressure sensor (113) is located in the first line (110), which detects the change in the system pressure value.
• first line flow meter (116) which measures the flow rate (flow rate) of the geo fluid in the first line (110).
• second line inlet pressure sensor (121) that measures the inlet pressure value of the geo-fluid and a second line outlet pressure sensor (124) that measures the outlet pressure value of the geo-fluid in the first line (120).
• second line inlet temperature sensor (122) which measures the inlet temperature value of the geo-fluid
• second line outlet temperature sensor (125) which measures the outlet temperature value of the geo-fluid in the second line (120).
• a second line differential pressure sensor (123) is located in the second line (120) that detects the pressure value change in the system.
• second line flow meter (126) which measures the flow rate (flow rate) of the geo-fluid in the second line (120).
