The geothermal power generating facilities that utilize the geothermal energy from the earth are environment-friendly, because they scarcely emit the greenhouse gases such as carbon dioxide (CO2) or the environmental pollution substances such as nitrogen oxides (NOx) and sulfur oxides (SOx). On the other hand, they should work swallowing the geothermal steam that contains much amount of chemical impurities such as hydrogen sulfides (H2S), sulfates (SO42-), chlorides (Cl-), silica (SiO2), etc. Therefore, it is not too much to say that the geothermal power generation is a fight against the chemical impurities. Since the first practical geothermal power generating facility in Japan began operating with a small capacity of 30kW in 1960 at Hakone Kowakien, Japanese manufacturers have been developing geothermal power generating facilities and supplying them worldwide. The geothermal power generation is one of the technical challenges that gives a hope for a sustainable development of the human society.
