Abstract: 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.
Abstract translation: 通过将包括水和液体组合物（例如海水或生产的压裂水）与定向溶剂混合以选择性地将水从液体组合物溶解到定向溶剂中，可以通过连续或半连续方法获得纯化水。 除去液体组合物的浓缩剩余物（例如盐水），并从定向溶剂中沉淀出水并以纯化形式除去。 然后在连续或半连续操作过程中重复使用溶剂。

Abstract: Cations that can precipitate from an aqueous composition to produce scaling are sequestered by adding a multi-dentate ligand to the aqueous composition. The multi-dentate ligand bonds with the cation to form a non-scaling ionic complex; and the aqueous solution with the ionic complex is used in a process that produces substantially pure water from the aqueous composition, where the cation, absent formation of the ionic complex, is subject to scaling. The pH of the aqueous composition (or a brine including components of the aqueous composition) is then reduced to release the cation from the multi-dentate ligand; and the multi-dentate ligand, after the cation is released, is then reused in a predominantly closed loop.
Abstract translation: 可以通过向水性组合物中加入多齿配体将螯合物从水性组合物沉淀以产生结垢。 多齿配体与阳离子结合形成非结垢离子络合物; 并且具有离子络合物的水溶液用于从水性组合物产生基本上纯的水的方法，其中离子络合物的形成不存在结垢的阳离子。 然后还原水性组合物（或包含含水组合物的组分的盐水）的pH以从多齿配体释放阳离子; 并且在释放阳离子之后的多齿配体然后在主要闭合的环路中重新使用。
