Abstract
The method includes: (A) directing a feed water in the liquid phase of an instant expansion tank; (B) in the instant expansion tank, heating the feed water by mixing with the recycled stream from step (E); (C) compressing again at a high pressure the liquid fraction in the instant expansion tank and sending the liquid fraction to the inlet of a heat exchanger or group of heat exchangers connected in series; (D) heating the non-expanded fraction in the heat exchanger(s) while maintaining the non-expanded fraction in the liquid state; (E) recycling the stream from step (D) in the instant expansion tank; (F) in the instant expansion tank, expanding the fraction from step (E) and generating by instant expansion a stream of the searched steam containing the mineral materials of the feed water remaining in solution; and (G) separating the solid particles formed as a blowdown containing water and the particles.
