The present disclosure relates to distillation apparatus, especially such apparatus that may be deployed within a commercial, domestic or near-Domestic situation to provide distilled water on demand. The distillation apparatus comprising an evaporation chamber, a condensation chamber, a heat source, the heat source being arranged to supply heat to at least part of the evaporation chamber, a fluid inlet, a fluid outlet, and a vapour compression pump, wherein the condensation chamber surrounds at least part of the evaporation chamber.

A method includes providing a resonant thermal oscillator in a thermofluidic system having at least two counter-flowing liquid streams separated by at least a spectrum absorbing material, wherein the spectrum absorbing material is hydrophobic, light-absorbing, and photothermal, and adjusting a flow rate in at least one of the counter-flowing liquid streams to maximize heat transfer between the at least two counter-flowing liquid streams.

A combined vessel comprises a stripping section for removing acid gases from a sour water stream and a direct contact heat exchanger section for heating a graywater stream in order to improve heat and mass transfer in the treatment and recycle of water streams for a gasification process.

A multi-waste processing system includes a processing chamber. The processing chamber includes one or more heaters and a piston, and the processing chamber is configured to evaporate liquid waste and compact solid waste input. A condenser is operably connected to the processing chamber. The condenser is configured to condense water from the evaporated liquid waste output from the processing chamber. A gas and water separator is operably connected to the condenser. The gas and water separator is configured to separate water from the evaporated liquid waste output from the processing chamber. A recirculation pathway connects the gas and water separator to the processing chamber to recirculate gas from the gas and water separator to the processing chamber. The piston is actuated to keep the one or more heaters in close proximity to the solid waste and the liquid waste in the processing chamber.

The present disclosure provides a solid waste treatment method, including following steps: screening off masses having a particle size greater than 0.5 cm from solid waste; adding extraction agents to the solid waste and then heating and stirring so that the solid waste is fully dispersed in the extraction agents; placing the mixed extraction agent in a centrifuge and centrifuging the mixed extraction feeding liquid phase separated by centrifuging into a rectification tower for rectification and cooling, recovering residual oil substances in a rectification kettle, separating mixture of cooled extraction agents and water, continuously adding the separated extraction agents into an extraction kettle for cyclic extraction, and conveying sewage to a sewage treatment plant to treat and discharging the sewage after the sewage reaches a treatment standard.

A water sanitizing system is disclosed and includes an inner chamber and an outer chamber disposed at least partially around the inner chamber. A lens concentrates solar energy applied to a liquid within the inner chamber. A vacuum source in communication separately with the inner chamber and the outer chamber. The vacuum source controls a pressure within the inner chamber separately from the outer chamber for controlling conversion of liquid within the inner chamber to a gas. The outer chamber, also under vacuum, is an insulative layer to prevent heat loss.

The present invention provides an improved catalytic fast pyrolysis process for increased yield of useful and desirable products. In particular, the process comprises an improved catalytic fast pyrolysis process for producing aromatic compounds, such as, for example, benzene, toluene and xylenes, from biomass feedstock containing impurities, such as, for example alkali and alkaline earth metal, sulfur and nitrogen components.

The invention relates to an arrangement for a latent-heat exchanger chamber, usable in distillation devices, which comprises an evaporator in a capillary evaporation regime on the inner face thereof and a condenser in a capillary condensation regime on the outer face thereof, with a system for the dosed supply of liquid into microgrooves or micro undulations of the inner evaporator face, preventing the formation of thin films of water on the evaporator face, the arrangement achieving high latent-heat transfer coefficients.

A waste water incinerating method comprising supplying waste water to an evaporator to evaporate the waste water, supplying an evaporator top discharge stream discharged from the evaporator to an incinerator to incinerate the discharge stream, mixing two or more incinerator discharge streams including a first incinerator discharge stream and a second incinerator discharge stream discharged from the incinerator to form a mixed discharge stream, and heat-exchanging the mixed discharge stream and a fresh air stream in a first heat exchanger, wherein the first incinerator discharge stream is passed through a second heat exchanger, then mixed with the second incinerator discharge stream to form the mixed discharge stream.

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.
