Estimating the Properties of the Multicomponent Geothermal Fluids Are Requisite. Imprecise Knowledge of Geothermal Water Properties, E.G. Isobaric Heat Capacity, Leads to Inaccurate Knowledge of Geothermal Water Heat Content and Thus to Inaccurate Knowledge of Heat Input to Geothermal Power Plants (SchröDer Et Al., 2015). in Early Geothermal Process Simulations the Geofluids Were Idealized as Pure Water, Nonetheless Many Geothermal Reservoirs Contain Significant Amounts of Salts and Non-Condensable Gases (Ncgs) Including h2s, n2, nh3, h2, ch4 and co2 (Michaelides, 1982), Where the Mass Fractions of Gases Could Be as High as 10 Percent (Fatma Bahar Hosgor, 2015). Presence of Salts And/Or Non-Condensable Gas Can Seriously Complicate Any Geothermal Fluid Simulation. for Instance, by Diss/Exsolution of Salts And/Or Ncg, Density of the Geofluid Can Be Significantly Affected. the Density Has a Strong Influence on the Calculated Volumetric Flow-Rate of the Production Pump (Francke and Thorade, 2010). in Case of the Thermosiphon Doublet, Density Affects the Thermosiphon Effect, I.E. Mass Flow-Rate of Geofluid Which Is Generated by the Density Difference of the Geofluid Between Injection and Production Wells (Adams Et Al., 2014). in Other Circumstances, Ncg Breakout (Exsolution) Plays Important Role to Scaling of Some Precipitant, I.E. Calcite, Stibnite, Which Are Associated with co2, h2s Concentration Ex/Dissolved in Brine (Baran Kaypakoglu, 2015). (Grimes, 2013) Showed That Sulfide Stress Corrosion Cracking of Low-Alloy Steels Is Correlated with the Fugacity (Or Equivalently Activity) of h2s. Salts and Ncgs Would Also Obscure Accurate Pressure-Drop Computations in Geothermal Wells (Hasan and Kabir, 2010). Furthermore, the Properties of Water-Salts-Ncg Is Prerequisite for Geo-Pressurized Resources and Carbon Capture Storage Hybrid Simulation. the Potential for Compensating the Cost of co2 Capture and Storage by Producing Large Quantities of Valuable Methane and Geothermal Energy Is Obviously Significant (Ganjdanesh Et Al., 2013). |
