A method of treating a liquid. The method comprises providing a feed liquid comprising at least one solvent and at least one solute to a first side of a membrane. A single-phase draw solution comprising at least one of an aminium salt, an amidinium salt, and a guanidinium salt is provided to a second side of the membrane. The at least one solvent is osmosed across the membrane and into the single-phase draw solution to form a diluted single-phase draw solution. At least one of CO2, CS2, and COS is removed from the diluted single-phase draw solution to form a first multiple-phase solution comprising a first liquid phase comprising the at least one solvent, and a second liquid phase comprising at least one of an amine compound, an amidine compound, and a guanidine compound. A liquid purification system is also described.
一种处理液体的方法。该方法包括向膜的第一侧提供由至少一种溶剂和至少一种溶质组成的进料液体。向膜的第二侧提供单相汲取溶液,该溶液包含铵盐、脒盐和胍盐中的至少一种。至少一种溶剂通过膜渗透到单相汲取液中,形成稀释的单相汲取液。从稀释的单相汲取溶液中去除 CO2、CS2 和 COS 中的至少一种,形成第一多相溶液,该溶液包括包含至少一种溶剂的第一液相,以及包含胺化合物、脒化合物和胍化合物中的至少一种的第二液相。还描述了一种液体纯化系统。
