WATER EXTRACTION USING A DIRECTIONAL SOLVENT

Purified water can be obtained via a continuous or semi-continuous process by mixing a liquid composition (e.g., sea water or produced frac water) including water with a directional solvent to selectively dissolve water from the liquid composition into the directional solvent. The concentrated remai...

Beschreibung
Zusammenfassung:	Purified water can be obtained via a continuous or semi-continuous process by mixing a liquid composition (e.g., sea water or produced frac water) including water with a directional solvent to selectively dissolve water from the liquid composition into the directional solvent. The concentrated remainder of the liquid composition (e.g., brine) is removed, and the water is precipitated from the directional solvent and removed in a purified form. The solvent is then reused as the process is repeated in a continuous or semi-continuous operation. Selon l'invention, de l'eau purifiée peut être obtenue à l'aide d'un processus continu ou semi-continu par mélange d'une composition liquide (par exemple, de l'eau de mer ou de l'eau de produit de fracturation) comprenant de l'eau à un solvant directionnel de façon à dissoudre de façon sélective l'eau à partir de la composition liquide dans le solvant directionnel. Le reste concentré de la composition liquide (par exemple, une saumure) est retiré, et l'eau est précipitée à partir du solvant directionnel et retirée sous une forme purifiée. Le solvant est ensuite réutilisé tandis que le processus est répété dans une opération continue ou semi-continue.
