摘要： Systems and methods for osmotically assisted desalination include using a pressurized concentrate from a pressure desalination process to pressurize a feed to the desalination process. The depressurized concentrate thereby produced is used as a draw solution for a pressure-retarded osmosis process. The pressure-retarded osmosis unit produces a pressurized draw solution stream that is used to pressurize another feed to the desalination process. In one example, the feed to the pressure-retarded osmosis process is impaired water.

摘要： Separation processes using forward osmosis are disclosed generally involving the extraction of a solvent from a first solution to concentrate a solute therein by using a second concentrated solution to draw the solvent from the first solution across a semi-permeable membrane. One or both of the solute and solvent may be a desired product. By manipulating the equilibrium of the soluble and insoluble species of solute within the second solution, a saturated second solution can be used to generate osmotic pressure on the first solution. The various species of solute within the second solution can be recovered and recycled through the process to affect the changes in equilibrium and eliminate waste products. Enhanced efficiency may result from using low grade waste heat from industrial or commercial sources.

摘要： An energy efficient desalination process that does not produce waste products involves the extraction of water from a first solution, such as seawater, by using a second concentrated solution to draw the water from the first solution across a semi-permeable membrane. By manipulating the equilibrium of the soluble and insoluble species of solute within the second solution in favor of the soluble species of the solute, a saturated second solution can be used to generate osmotic pressure on the first solution. Also, by adjusting the equilibrium in favor of the less soluble species after the water has been drawn from the first solution, a portion of the solute can easily be precipitated out. Heating the second solution decomposes the solute into its constituent gases. The constituent gases and precipitated solute may be recycled through the process to affect the changes in equilibrium and eliminate waste products. Additionally, by using the waste steam from industrial sources and a heat pump to effectively distribute heat through the present method, the present method exhibits greater energy efficiency than prior art methods.
摘要翻译：不产生废物的能量高效脱盐方法涉及通过使用第二浓缩溶液从第一溶液中通过半透膜抽出水从第一溶液（例如海水）中提取水。通过操纵第二溶液中可溶性和不溶性溶质的平衡，有利于溶质的可溶性物质，可以使用饱和的第二溶液在第一溶液上产生渗透压。此外，通过在从第一溶液中抽出水后，通过调节有利于较少溶解物质的平衡，溶质的一部分可以容易地沉淀出来。加热第二溶液将溶质分解成其组成气体。组分气体和沉淀溶质可以通过该过程再循环，以影响平衡的变化并消除废物。此外，通过使用来自工业源的废蒸汽和热泵通过本方法有效地分配热量，本方法比现有技术方法显示出更大的能量效率。

摘要： A process for recovering solvents from inorganic and organic solutions is disclosed. The process utilizes a polymer capable of selectively extracting the solvent from the inorganic or organic solution. Introduction of the polymer into the solvent solution creates formation of a polymer-rich phase and a solute-rich phase. The recovered solvent may be separated from the polymer-rich phase by heating the polymer-rich phase to at least the cloud point of the polymer. The polymer and/or solute may be re-cycled for further use in the solvent recovery process.
