20140367347 | METHODS AND SYSTEMS FOR PROCESSING MULTICOMPONENT SOLUTIONS OF MINERAL SALTS - 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. | 12-18-2014 |
20150020541 | METHODS AND SYSTEMS FOR UNDERWATER GAS PRESSURIZATION AND LIQUEFACTION - 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. | 01-22-2015 |
20150020542 | UNDERWATER GAS FIELD DEVELOPMENT METHODS AND SYSTEMS - 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. | 01-22-2015 |

The heavy water-immiscible liquid has a higher density than the aqueous salt solution, the aqueous salt solution has a higher density than the light water-immiscible liquid and the light water-immiscible liquid has a higher density than sea water to maintain the intermediate layer on top of the bottom layer, the top layer on top of the intermediate layer and the top layer in the liquid column. | 01-22-2015 |
20150021421 | UNDERWATER MINERAL DRESSING METHODS AND SYSTEMS - Underwater mineral dressing units, systems and methods are provided. Material is milled in a water-immiscible liquid which is heavier than water and lighter than the product material. Gangue material is removed by the milling and floats on the water-immiscible liquid to be removed without further processing. Product containing material sinks and is further milled to remove additional gangue material, until the required level of extraction is achieved. Cascades of milling rolls in the water-immiscible liquid allow ever improving extraction of the product material. The rolls are arranged to regulate material flow through the system to remove floating gangue while directing sinking product material to further processing. | 01-22-2015 |
20150027931 | PROCESSING COMBUSTIBLE MATERIAL METHODS AND SYSTEMS - Methods, systems and units for liquefaction of combustible material are provided. After separating the combustible material from waste rock gravitationally in an aqueous salt solution selected to have a density which is intermediate between a density of the combustible material and a density of the waste rock and after heating and grinding the separated combustible material to yield a paste of purified combustible material, the paste is fluidizing and hydrogenated underground in a hydrogenation chamber including a Segner turbine. The described processes significantly reduce the energy consumption of the process, remove environmental hazards and result in more efficient liquefaction with respect to existing technologies. | 01-29-2015 |
20150047388 | METHODS OF DESALINATION AND RINSING, AND SYSTEMS THEREFOR - 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. | 02-19-2015 |

The process involves adding at least one organic polymeric flocculant to the first aqueous suspension to form a suspension of flocculated solid. The flocculated solids settle to form a bed of consolidated solids. Introducing an effective amount of an agent into the bed of consolidated solids or into the flocculated solids that are settling leads to formation of the second aqueous suspension. The second aqueous suspension of solid particles has a higher solids content than the first aqueous suspension of solid particles. The agent is a free radical agent or an oxidizing agent. | 02-28-2013 |
