An improved solar water distillation system including: a flow system for collecting one or more condensate streams from an input treatment liquid; and an input treatment liquid separator within the flow system adapted to collect excess input treatment liquid from the flow system separate from the one or more condensate streams. The treatment liquid is maintained separate to the condensate streams to substantially minimise cross-contamination of the one or more condensate streams.

A method includes: providing a carbon dioxide recycle stream comprising natural gas liquids; separating, using a first distillation tower, the carbon dioxide recycle stream into a first vapor fraction and a first liquid fraction; cooling and partially condensing the first vapor fraction in a heat exchanger to yield a first carbon dioxide stream and a reflux stream; and separating, using a second distillation tower, the first liquid fraction into a second carbon dioxide stream and a natural gas liquids rich stream.

The distillation apparatus of the disclosed technology has a bulbous bottom side which extends below a plane defined by an outer cover which circumscribes a rest of a lower collector region which has there-within the bulbous or spheriod end. Further within the outer cover and/or functionally connected to the lower collector region is a vertical tube passing both into an area circumscribed by the lower collector region as well as passing into an area circumscribed by a fraction collector situated there-above. The fraction collector can have a same width (horizontal directional extent) as the lower collector region at a widest portion thereof. A rejection area can be created beneath the spheroid bottom end of the lower collector region as well at an interior top side of the lower collector region outside of the vertical tube.

A CO.sub.2 extraction process for cannabis sativa that uses liquid CO.sub.2 in combination with co-solvent admixtures to purify cannabis botanicals in high yield and purity. The extraction process allows for multiple extractions, or washes, to be performed with the same solvent CO.sub.2, which may be seamlessly recycled and purified between subsequent extraction cycles. A variety of in-line filtration vessels, pumps, vacuums, and controllable valves are used to yield a pure product while allowing a high level of user control over the process.

Systems and methods for recuperative heat exchange are described herein. Recuperative heat exchange assemblies can comprise longitudinally extending heat exchange plates defining alternating hot-side layers and cooling layers. Furthermore, water generation systems and related methods of generating water from air are disclosed herein. Water generation systems and related methods can comprise a sorption unit comprising a hygroscopic material to capture water vapor from ambient air, a thermal unit to heat the hygroscopic material and transfer water vapor released therefrom to a regeneration fluid, and a recuperative heat exchange assembly to drive condensation of water vapor from the regeneration gas to produce liquid water. Disclosed water generation systems and related methods may include a valve assembly having a slide plate movable transversely to a flow channel axis between a plurality of positions.

A machine for vacuum treatment of food products, which includes a base structure which defines a vacuum chamber which can be connected to a vacuum pump. At least one filtration device is interposed between the vacuum chamber and the vacuum pump and has elements for varying at least one thermodynamic/fluid dynamics parameter of the air flow aspirated by the vacuum pump; the filtration device includes at least one conveyor of the air flow, which is provided with elements for varying the advancement direction of the air flow and which is, with at least one part thereof, in a heat exchange relationship with a cooling circuit, and at least one collection manifold for collecting the water and the particles separated from the air flow.

An apparatus and system for producing fresh water from moisture-laden air. The apparatus has a frame supporting a plurality of condensation panels that each have a panel body defining a pair of condensation surfaces that will contact the moisture-laden air. A panel support mechanism supports each of the condensation panels in spaced apart relation to each other so each condensation surface contacts moisture-laden air. A flow channel inside the panel body defines a flow path for a cooling fluid that cools the condensation surfaces so the moisture-laden air will produce condensate thereon that collects as fresh water. The system includes a plurality of apparatuses, a chilling mechanism to cool the cooled fluid, inlet and discharge lines connecting the chilling mechanism and apparatuses, pumps to pressurize the cooled fluid, fans to move the moisture-laden air and water collecting surfaces to collect the fresh water.

A system and method removes thermal decomposition components from biphenol and/or diphenyl oxide heat-transfer fluids. Light, volatile decomposition components including benzene, water, hydrogen and phenol leave the system for vapor recovery, chemical adsorption or thermal decomposition. Dimerized and polymerized heavy components such as biphenyl phenyl ether, terphenyl and related isomers are concentrated and recovered. The system can be a continuous, semi-continuous or batch operation. Solar electric plants employing the system can use solar field fluids and heating to operate the system during generator operation hours. A wash system operating at or near atmospheric pressure concentrates heavy thermal decomposition components while allowing removal of light, volatile decomposition components for separation from the majority of the thermal fluid components. Temperature-controlled condensation of the majority of the thermal fluid components allows collection of the thermal fluid, while allowing light, volatile decomposition components to be removed prior to vent processing.

There is provided a liquid water harvester based on a valve-controlled active air supply and belongs to the field of liquid water harvesters. The present disclosure aims to address the problem of low airflow speed, high environmental humidity requirements, and auxiliary heating of an adsorption stage in the current atmospheric water harvesting technologies. In the present disclosure, the active air supply device is used to speed up the air circulation in the harvester so as to greatly shorten the adsorption time of the moisture absorbing material for the water vapor in the air and improve the heat dissipation of the micro-nano structure condensation surface. The electric valve controls the air circulation circuit and cooperates with the active air supply device. In this case, only one active air supply device can be used to complete the air supply and the condensation heat dissipation at the same time.

The wireless communications device may be further configured to display an outside temperature, an outdoor humidity, a water level, an indoor temperature, an indoor humidity, and a dew point. The wireless communications device may be further configured to receive control instructions, and wherein the wireless communications device is further configured to communicate the control instructions to the atmospheric water generator.
