1. Introduction
Geothermal energy is anabundant alternative renewable energy resource. Geothermal energy is the heat energy generated by the radioactive decay of long lived isotopes like potassium, uranium, radium and thorium in the earth’s crust. It can be recovered as steam or hot water beneath the earth’s surface, such as those in hot springs and used as a source of energy. Geothermal energy provides base-load power just like any other energy sources such as coal, oil or natural gas, and can replace fossil fuels. Geothermal power is cost effective, reliable, sustainable, environmentally friendly and virtually inexhaustible [1]. The geothermal areas or fields can be geographically classified based on their location: Volcanic or high temperature areas that lies close to active volcanoes and non-volcanic or low temperature areas that lies outside the active volcanic belts [2]. A 3 MW power plant was established in Ching-Shui non volcanic geothermal field in 1981 in Taiwan. The plant was decommissioned in 1993 due to continued decline in production. The main cause behind this operational failure was the occurrence of mineral deposits in geothermal wells, pipelines and reservoir fractures [3,4]. The mineral deposits in wells and fractures were identified as calcite (CaCO3). Calcite is a common formation mineral that often occurs as travertine deposits around neutral Na-HCO3-SO4 springs. In general, calcite can be generated by one of the following ways: (i) hydrolysis (involving replacement of calcium alumino-silicates), (ii) boiling of geothermal fluids (from fluids having high dissolved carbon dioxide concentrations and in the absence of mineral pH buffer) and (iii) heating of cooler peripheral geothermal fluids [5,6]. The difficulty of running a geothermal power plant in a nonvolcanic area is de-trop calcite growth, when the geothermal fluid boils or degases in response to a pressure drop [7,8]. Most dissolved CO2 is lost from the liquid phase into gaseous phase at the flash point and this causes a dramatic shift in the following equilibrium to the right [9]:
