| Abstract | This software, Geomizer is designed for the geothermal power plants for predicting mineral scale formation and inhibiting the same using Chemical scale inhibitors. The web application is capable of modeling multiple configurations or layout for the geothermal power plant and performs process study. The process models include process unit operations and streams which can be stored and retrieved for later use. This application is also capable of blending of multiple brines for predicting the scaling and corrosion issues and developing a well profile for individual or mixed brines. The paper describes the architecture to predict scaling in all parts of the nominated geothermal process such as production wells, Flash separation, Binary heat exchangers, Geyser (Dry Steam) systems and Reinjection wells by using a standard thermodynamic modeling tool. The software helps the scale prediction and optimization can be done for all the processes in the geothermal plant. The application predicts the distribution of gaseous contaminants at variable pressures and temperatures and the impact on the water chemistry. The application delivers an output that includes all the integrated components in a visually pleasing layout, with detailed pages for each separate unit operation. Based on the thermodynamic calculations and the various scale and corrosion inhibition models imbedded into the software, an optimum dose of the Scale and Corrosion inhibitor is predicted. Verification of the predicted dose from software and the successful application in the field is also discussed. |
