Wind and wave desalination vessel

The present invention provides a novel floating and renewable energy-powered desalination vessel, which also functions as a wind turbine generator and wave energy generator platform. With energy derived from the wind and waves, the vessel performs reverse osmosis within a vertically positioned cylindrical section extending below a buoyancy chamber. The cylindrical section contains reverse osmosis membranes located above a seawater screening and filtration system, which serve as ballast. The entire vessel and power systems are configured to have the center of mass below the center of buoyancy, forming a vertically stable floating structure with minimum pitch, roll, and wave heave in high sea states. The electric power generated is utilized internally to produce desalinated water or hydrogen from the desalinated water's electrolysis, power an onboard data center, or power delivery to a shoreside power grid. In addition to a wind turbine generator and a wave energy generator, a photovoltaic array or a marine current generator may be utilized to power these applications. Alternatively, the desalination vessel operates with the assistance of shore-based power provided by cable.

TURBINE EXHAUST GAS SYSTEM USING PRODUCED WATER AND OZONE INJECTION
20220332598 · 2022-10-20 ·

A system and apparatus for treating and disposing of produced water in conjunction with gas turbine exhaust gas, thereby avoiding problems associated with injecting produced water back into subsurface strata. The system is installed at or near the wellhead where produced water being treated is at a higher temperatures. Produced water is treated with ozone injection in a scrubber with heat applied through introduction of gas turbine exhaust gas. A wet scrubber unit with scrubber packing is used to clean emissions. A produced water pump is used to circulate produced water, and pump produced water through spray nozzles in the scrubber unit for use as the wet scrubbing agent. As produced water evaporates, evaporated salts and solids are continuously removed from the evaporator/scrubber unit by appropriate means, such as an auger system. The evaporated salts and solids are then treated via chemical stabilization in a mixing system with chemical reagents to prevent the residual form from being hazardous. The residual material is then stored and disposed of properly.

Potable water producing device

A water treatment device comprising a clear container with lid surrounded by a solar reflector, and an insert in the form of a thin sheet or mesh permanently coated with titanium dioxide as a water sanitizing catalyst. The container is filled with non-potable water, covered with the lid, and placed in direct sunlight. Direct and reflected sunlight enters the water through the clear container and lid, where the sunlight's ultraviolet (UV) radiation and increased solar thermal heat disinfect the water. Further, the catalyst on the insert reacts with dissolved oxygen in the water to produce reactive oxygen species. These reactive species react with and decompose organic compounds in the water, and kill or inactivate pathogens. In addition, the reactive oxygen species further react with the water itself to produce additional free radical species, which also react with and decompose organic compounds and kill or inactivate pathogens.
