ABSTRACT:
In a geothermal electric power generating plant of the type wherein a flow stream of hot geothermal brine from a production well is partially flashed to steam for turbine motive power, system and method for removing most of the entrained noncondensable gas content of the brine proximate the high temperature end of the plant, while at the same time recovering most of the heat energy from steam necessarily released with the noncondensable gases. The noncondensable gases such as carbon dioxide, hydrogen sulfide, ammonia, and boric acid, together with a substantial amount of high pressure, high temperature steam, are separated from the brine flow stream before its entry into conventional flash portions of the plant. A heat exchange system is employed to transfer heat from the separated steam and its condensate and from the separated gases to substantially pure turbine exhaust water condensate so as to boil the pure water for turbine motive steam. The resulting heat loss from the separated steam condenses it and thereby separates out the noncondensable gases. Removal of the noncondensables enables a substantial increase in net plant power output to be achieved, and substantially reduces plant capital costs and maintenance expenses.
