Abstract
Steam is produced from low quality feedwater. A feedwater stream and a superheated steam stream are introduced into a contactor vessel where the superheated steam is contacted with the feedwater thereby producing saturated steam in the contactor vessel and precipitating minerals from the feedwater in the contactor vessel. The produced steam is withdrawn from the contactor vessel and divided into a primary stream and a secondary stream. The primary stream of produced steam is flowed to a use terminal such as a well for injecting the same into a subsurface formation as part of a steam flood system or such as a steam turbine. The secondary stream of steam is superheated and recycled to the contactor vessel. Waste water containing the solid minerals precipitated from the feedwater within the contactor vessel is withdrawn from the contactor vessel through a waste water discharge conduit.
