  • Patent number: 10161114
    Abstract: This invention is designed to create potentially unlimited commercial fresh water at a significantly reduced cost in relation to existing fresh water creation systems such as sea water desalination. This invention pumps coastal atmospheric air through sealed pipes to ocean water depths (ideally) of approximately 100-305 meters, or (ideally) into the local ocean's thermocline layer. Fresh water condensation occurs inside the sealed air pipes as cold ocean water chills the outside of the pipes. Condensation fresh water flows via gravity to the low point in the sealed air pipes where a powered fresh water pump is located. This powered fresh water pump then pumps the accumulated condensation water to the ocean surface and then on to shore as usable fresh water. The pumped-in air, now dehumidified, is piped to the surface and returned to the atmosphere.

  • Patent number: 9932257
    Abstract: A process treats high temperature produced water by passing a stream to an electrocoagulation unit and then to a membrane distillation (MD) unit where the stream contacts a hydrophobic membrane on a feed side and deionized water contacts the membrane on a product side. A distilled water stream is recovered and collected with the product side stream to form a volume-depleted exit produced water stream on the feed side of the hydrophobic membrane. The exit product side stream is passed through a heat exchanger to form a stream that is returned to a location upstream of the MD unit for an additional pass through the MD unit, thereby recovering additional water. The stream can be returned multiple times to achieve high recovery and to form a final stream leaving the MD unit having a temperature from 40-60 ° C., a total oil and grease content no greater than 500 mg/L, and a suspended solids content no greater than 200 mg/L.

  • Patent number: 9926208
    Abstract: Water containing one or more solvents miscible in the water is heated to its boiling point. Air is introduced into the vapor mixture of steam and the miscible solvent at an air-to-steam volumetric ratio that is sufficient to get good transfer of the miscible solvent from the steam to air and provides an equilibrium temperature of the steam-air mixture compatible with operations of the heat exchanger. The mixture of gases is then rapidly cooled to condense the steam into water so that a substantial portion of the miscible solvent remains volatilized in the air. The air and condensed steam fractions are separated.

  • Patent number: 9453457
    Abstract: A portable on-demand hydrogen supplemental system is provided for producing hydrogen gas and injecting the hydrogen gas into the air intake of internal combustion engines. Hydrogen and oxygen is produced by an electrolyzer from nonelectrolyte water in a nonelectrolyte water tank. The hydrogen gas is passed through a hydrogen gas collector. Nonelectrolyte water mixed with the hydrogen gas in the hydrogen gas collector is passed back thru the tank for distribution and water preservation. The system can be powered by the vehicles alternator, a standalone battery, waste heat or solar energy. The system utilizes an onboard diagnostic (OBD) interface in communication with the vehicle's OBD terminal, to regulate power to the system so that hydrogen production for the engine only occurs when the engine is running. The hydrogen gas is produced it is immediately consumed by the engine. No hydrogen is stored on, in or around the vehicle.

  • Patent number: 9315396
    Abstract: Synergies in recovery of reverse osmosis (RO) membrane process reject waste and forward osmosis (FO) membrane process water extraction, using such osmotic process byproducts in applications for makeup to evaporative cooling towers, concurrent with use of specific corrosion and scale inhibition methods that permit tower water discharge reduction to approach zero blowdown. Such synergies are derived from methods for application of subsequent RO feed water and reject wastewater with pre-treatment steps, and FO process optimization steps to permit water quality and economic performance efficiencies when used as makeup to evaporative cooling systems.

  • Patent number: 9150429
    Abstract: The solar, water desalination system includes a desalination chamber where fine water droplets are injected upward by an air atomizer towards an air-cooled condenser. Hot saline water is ejected vertically upward to double the contact time between the droplets and the surrounding air. The air is preheated by solar energy in parallel with an auxiliary heater to prevent lowering of the droplet temperature. Pumped air functions as a condensation media and to pull the salt water into the atomizer. This arrangement improves the heat and mass transfer inside the desalination chamber.
