This patent describes, in a geothermal electric power generating plant of the type wherein a flow stream of hot geothermal brine is partially flashed to steam for turbine motive power, a system for removing entrained materials from the flashed steam. It comprises: at least one flash crystallizer vessel having a lower portion which receives the brine flow stream and in which a portion thereof is flashed to steam, and an upper portion through which the flashed steam flows upwardly and from which the flashed steam is conducted to steam turbine means; and a baffle tray system within the upper portion of the vessel comprising a plurality of generally horizontal, generally vertically spaced baffle trays that define a sinuous upward flow path for the flashed steam which produces a series of substantial centripetal accelerations of the upwardly flowing steam so as to centrifugally separate the entrained materials from the steam onto surface portions of the baffle trays and wall portions of the upper portion of the vessel.
