    • Methods and apparatus for desalination of salt water (and purification of polluted water) are disclosed. Saline (or otherwise polluted) water is pumped to a desalination installation and down to the base of a desalination fractionation column, where it is mixed with hydrate-forming gas or liquid to form either positively buoyant (also assisted buoyancy) or negatively buoyant hydrate. The hydrate rises or sinks or is carried into a lower pressure area and dissociates (melts) into the gas and pure water. In preferred embodiments, residual salt water which is heated by heat given off during formation of the hydrate is removed from the system to create a bias towards overall cooling as the hydrate dissociates endothermically at shallower depths, and input water is passed through regions of dissociation in heat-exchanging relationship therewith so as to be cooled sufficiently for hydrate to form at pressure-depth. The fresh water produced by the system is cold enough that it can be used to provide refrigeration, air conditioning, or other cooling; heat removed from the system with the heated residual water can be used for heating or other applications. In other embodiments, desalination or other purification is carried out in "artificially" or mechanically pressurized vessels, which embodiments may be comparatively mobile. Such pressurized systems can be used to capture carbon dioxide from industrial waste gases and to provide liquid carbon dioxide.
    • 公开了盐水脱盐(和污水净化)的方法和装置。 盐水(或其他污染的)水被泵送到脱盐装置并且直到脱盐分馏塔的底部,在其中与形成水合物的气体或液体混合以形成正浮力(也辅助浮力)或负浮力水合物。 水合物上升或下沉或被运送到较低的压力区域并解离(熔化)到气体和纯水中。 在优选的实施方案中,当在水合物形成期间被排出的热量被加热的残余盐水从体系中除去以产生对整体冷却的偏压,当水合物在较浅的深度处吸热分解时,并且输入的水通过解离区域 与其进行热交换关系,以充分冷却水合物以形成压力深度。 系统产生的淡水足够冷,可用于提供制冷,空调或其他冷却; 用加热的残余水从系统中除去的热量可用于加热或其他应用。 在其它实施方案中,脱盐或其它纯化在“人工”或机械加压的容器中进行,这些实施方案可以相对移动。 这种加压系统可用于从工业废气中捕获二氧化碳并提供液体二氧化碳。
