Method and plant for fluid purification by distillation comprising a reservoir (1) with a fluid containing diluted solids provided with an impurities filter on its outlet (2); a pump (3) connected to the reservoir outlet (1) and set up to increase the fluid containing solids pressure and temperature; and a heat area (4) for the fluid containing solids comprising a plurality of ducts contacting with a heat transfer fluid; and, furthermore, comprising a convergent-divergent nozzle (5) connected to the heat area outlet (4) and set to increase the biphasic liquid-vapor fluid speed so the diluted solids contained in the fluid already heated settle in a solids reservoir (6), whereas the fluid passes to a condenser (7) and then to a purified fluid reservoir (8) already in liquid state.

A method may include providing a humidification-dehumidification unit proximate one or more abandoned wells, circulating a water feed through the one or more abandoned wells, using geothermal heat in the one or more abandoned wells to heat the water feed, directing the heated water feed to the humidification-dehumidification unit, and treating the heated water feed in the humidification-dehumidification unit to provide purified water.

A direct air capture system for use in a body of water that has waves with wave motion. The system includes at least one module exposed to the waves. The relative motion between the module and the waves to draws air into the module. The system removes carbon dioxide from the air using a moisture swing absorbent to remove the carbon dioxide from the air. The removed carbon dioxide can be used for various purposes.

A small processor produces potable water from contaminated water. Its components mount in a hermetically sealed housing, which include a boiler-condenser assembly and a compressor unit. Contaminated water is injected onto one or more aluminum shells' inside surface of the boiler-condenser assembly. Shell rotation enhances boiling heat transfer by causing the water to form thin films on the shells' inside surface. Shell rotation also enhances condensing heat transfer by assisting in removing the purified condensate from the shells' outer surface. The change of phase heat of condensation energy from vapor to liquid transfers through the shells to the boilers to cause boiling. Vapor boiled inside the boiler chambers flows toward the compressor, which raises the vapor's pressure and temperature to drive the process. Shell rotation causes centrifugal force that holds and directs concentrated un-boiled remaining water on the shells' inside walls towards the output pumps. Wipers mounted adjacent each shell's boiler surface smooth contaminated water. Wipers adjacent the condenser surfaces help remove condensate from that surface to present a clean condenser for improved condensation.

A multi-stage flash reversal unit includes a housing; plural stages located inside the housing; an evaporation port that receives a water feed having a first temperature; a condensation port that outputs a concentrated water feed having a second temperature, which is lower than the first temperature; and a cooling unit that cools down the concentrated water feed.

The present disclosure relates to isolating one or more cannabinoids from an input mixture. There is disclosed an apparatus that comprises a mixing vessel, a volatizing unit, and a distillation unit. The mixing vessel combines a first input mixture and a high boiling-point carrier agent to generate a second input mixture. The volatizing unit volatilizes cannabinoids from the second input mixture for separating the mixture into a cannabinoid-containing vapor stream and a residue. The distillation unit receives the cannabinoid-containing vapor stream and separates a first cannabinoid from at least a second cannabinoid. There are also disclosed methods that comprise the steps of combining a first input mixture with a high boiling-point carrier agent to provide a second input mixture, volatilizing the second input mixture into a vapor stream containing one or more cannabinoids and a residue, and separating a first cannabinoid from a second in the distillation unit.

A method of recovering draw agent utilised in a forward osmosis membrane cell, the method comprising the steps of passing diluted draw agent to a vapour-liquid separator; using the vapour-liquid separator to separate draw agent vapour and solvent; and condensing draw agent vapour.

This disclosure generally relates to gas-phase methods to distill molecules from a composition that is suspended in a gas.

Falling film evaporator systems, devices, and methods are disclosed in the present application. In some embodiments, the falling film evaporator system can include a hollow cylindrical glass tube configured to enclose the major parts of the falling film evaporator system. Furthermore, in some embodiments, inserted into the cylindrical glass tube is another hollow evaporator tube with a dispensing bowl at the top, a reservoir of the dispending bowl facing the inside top of the cylindrical glass tube. Inserted into the hollow evaporator tube is a heating element configured to heat the hollow evaporator tube such that an outside surface of the evaporator tube is heated. At the top of the hollow cylindrical glass is an inlet where liquid flows into the dispensing bowl, spilling over the edges of the bowl, generating a thin film of liquid that is evaporated as it falls down the outside surface of the evaporator tube.

A method for producing valuable organic liquid from a biomass wherein a heated gas is mixed with a biomass to produce an enriched organic vapor and a biomass waste product. The biomass waste product is separated from the enriched organic vapor. The enriched organic vapor is cooled to produce a liquid organic oil and the liquid organic oil is collected. A system for producing the liquid organic oil including a first separation unit to separate an enriched organic vapor and a biomass waste product. The enriched organic vapor and the biomass waste product are generated from mixing a heated gas and a biomass. The system also includes a wet scrubber for cooling the enriched organic vapor to generate an enriched organic smoke. The organic smoke can be transformed to the liquid organic oil in an electrostatic precipitator.
