Abstract
Steam is produced from aqueous brine, by a process that employs hot fluid, nozzle means and rotary separator means. Process steps include: PA1 (a) transferring heat from said hot fluid to said brine, PA1 (b) passing the heated brine in pressurized state to the nozzle means for flow therethrough, and expanding the flow therein thereby to form steam and liquid droplets, and PA1 (c) causing said expanded flow to rotate the rotary separator means for forming a layer of said brine on the separator means and accompanied by steam separation and for subsequent removal. The liquid from the rotating layer and/or the separated steam may be used to drive turbine means; the hot fluid may comprise combustion products from a combustion source; and several stages of separators may be employed.
