ABSTRACT:
Method of treating hard water containing dissolved and/or suspended volatile non-aqueous material, in which the water is heated by direct contact with steam to precipitate the hardness and resulting in three phases, namely, a gas phase comprising steam and vapor of volatile non-aqueous material, a soft water phase and a sludge (precipitate) phase. The gas phase is separated carrying with it the volatile non-aqueous components derived from the feed water. The soft water phase is separated from the sludge. The separated water phase is free or substantially free of volatile non-aqueous material and is suitable for use in a once through steam generator to produce saturated steam. The steam used to heat and strip the feed water is generated outside the process and preferably is steam generated in a conventional steam generator from a portion of the soft water produced in the process. The remainder of the soft water may be used to generate steam, e.g., to inject into an oil field to augment recovery of heavy viscous oil. The method is particularly applicable to brine produced with oil in certain oil fields.
