Patent number: 9771277Abstract: An evaporative system for separating solid salt from a saline solution is provided. The system comprises conveyor belts arranged to move the saline solution and evaporate water from it, using natural solar radiation, reflected solar radiation, mechanically induced evaporation and heat storing materials, which accumulate heat during the day and release the heat during the night to allow continuous production. The system may be adapted to different saline solution sources and terrain conditions as well as to varying meteorological conditions. The conveyor belts may be interspaced by separators that remove from the saline solution each type of salt as it solidifies on the corresponding conveyor belt. Conveyor belts may further be used to deliver the solid salt or wastes back to saline solution source.Type: GrantFiled: July 25, 2013Date of Patent: September 26, 2017Assignee: S.G.B.D.

Patent number: 9664019Abstract: Underwater gas pressurization units and liquefaction systems, as well as pressurization and liquefaction methods and gas field development methods are provided. Gas is compressed hydraulically by seawater introduced into vessels and separated from the gas by a water immiscible liquid layer. Tall, possibly vertical helical vessels are used to reach a high compression ratio that lowers the liquefaction temperature. Cooling units are used to liquefy the compressed gas, possibly by a coolant which is itself pressurized by a similar mechanism. The coolant may be selected to be liquefied under surrounding seawater temperatures. The seawater which is used to pressurize the gas may be used after evacuation from the vessels to pressurize intrastratal gas in the production stages and broaden the gas field development.Type: GrantFiled: August 1, 2013Date of Patent: May 30, 2017Assignee: S.G.B.D.

Patent number: 9664441Abstract: Underwater gas pressurization units and liquefaction systems, as well as pressurization and liquefaction methods are provided. Gas is compressed hydraulically by a rising pressurization liquid that is separated from the gas by a water immiscible liquid layer on top of an aqueous salt solution. Tall vessels are used to reach a high compression ratio that lowers the liquefaction temperature. The pressurizing liquid is delivered gravitationally, after gasification, transport to smaller water depths and condensation. Cooling units are used to liquefy the compressed gas. A cascade of compression and cooling units may be used with sequentially higher liquefaction temperatures, which allow eventual cooling by sea water. The pressurizing liquid, dimensions of the vessels, the delivery unit, the coolants and the implementation of the cooling units are selected according to the sea location, to enable natural gas liquefaction in proximity to the gas source.Type: GrantFiled: July 25, 2013Date of Patent: May 30, 2017Assignee: S.G.B.D.

Patent number: 9458030Abstract: Desalination and rinsing methods and systems are provided, which use a liquid column to efficiently perform freeze desalination and enable recyclable washing of produced minerals or combustible material. The liquid column comprises alternating layers of water immiscible liquids and water solutions which form a vertical density gradient (discrete or continuous) and exhibit a lower freezing zone from which ice floats to an upper melting zone. Cooling of introduced upwards flowing salt solutions is carried out by a countering downwards flow of cold water immiscible liquid. The process is cyclical, involves few if any mechanical moving parts and is easily controllable and adaptable to varying desalination circumstances. Rinsing of minerals or combustible material may be integrated in the heat and matter flows of the desalination system to allow effective rinsing, desalination and recycling of the used water.Type: GrantFiled: August 27, 2013Date of Patent: October 4, 2016Assignee: S.G.B.D.
