Many kinds of trouble peculiar to geothermal power generation have been experienced by not a few geothermal power plants in service world wide. On the other hand, there are some geothermal power plants, which have remained in successful operation over twenty years with an extremely high level of availability. In nearly all instances, geothermal steam contains harmful impurities and gas, such as chlorine, hydrogen sulfide, and carbon dioxide, that give rise typically to corrosion and corrosion fatigue of main or ancillary machineries in the geothermal power plants. Steam gathering system, especially steam separator in the hot-water geothermal field, is a key factor in maintaining successful geothermal power plant operation. Chlorine in geothermal steam, carried over as fine drift of brine, corrodes ferrous alloy.
