METODO ED APPARECCHIATURA PER IL TRATTAMENTO IN RIBOLLITORE DI PRODOTTI GEOTERMICI

摘要

Appts. for handling geothermal brine is capable of being flashed to form a vapour fraction including steam and a non-condensible gas. It comprises (a) flashing geothermal brine in a first zone; (b) moving the vapour fraction of the flashed geothermal brine to a second zone spaced from the first zone and into countercurrent heat exchange relationship to a fluid to separate the steam from the non-condensible gas and to heat the fluid; (c) flashing the heated fluid in a third zone to provide pure steam and a fluid remainder; (d) using the pure steam from the third zone for driving a work producing device; and (e) directing the fluid remainder to the second zone for heat exchange relationship to the vapour fraction from the first zone.
