An apparatus and method for extraction of oils from botanical material using high-pressure hydrocarbons such as propane, or butane, or mixtures thereof are described. A high-pressure propane or butane saturated liquid/vapor mixture formed by pressure reduction through a valve placed before an extraction column, thereby serving as an expansion port was employed. The apparatus is capable of both continuous liquid extraction or batch-style liquid operation through the use of a manifold valve, which directs the solvent liquid/vapor in the system to either a supply tank or an extraction column.

Systems and methods for operating a water recovery system are described and include activating a condenser of the water recovery system. The method includes measuring a temperature associated with the condenser based on data obtained from a condenser temperature sensor. The method includes comparing the temperature associated with the condenser to a maximum threshold temperature. The method includes activating an auxiliary condenser of the water recovery system in response to the temperature associated with the condenser being greater than the maximum threshold temperature.

A dialysis system (e.g., a hemodialysis (HD) system) can be designed to operate in alternative environments, such as disaster relief settings or underdeveloped regions. The dialysis system can include a solar panel for generating electricity to power the dialysis machine and an atmospheric water generator for extracting water from ambient air. The extracted water can be used to generate dialysate and saline on-site. One or more of the components of the dialysis machine can be discrete components that are configured to facilitate fast shipping and simple on-site assembly (e.g., at a remote location). In some implementations, the discrete components may be configured to be attached to an existing dialysis system (e.g., a dialysis system designed for operation in a traditional environment) to permit the dialysis system to operate in an alternative environment.

The invention provides a method for computational fluid dynamics and apparatuses making enable an efficient implementation and use of an enhanced jet-effect, either the Coanda-jet-effect, the hydrophobic jet-effect, or the waving-jet-effect, triggered by specifically shaped corpuses and tunnels. The method is based on the approaches of the kinetic theory of matter providing generalized equations of fluid motion and is generalized and translated into terms of electromagnetism. The method is applicable for slow-flowing as well as fast-flowing real compressible-extendable generalized fluids and enables optimal design of convergent-divergent nozzles, providing for the most efficient jet-thrust. The method can be applied to airfoil shape optimization for bodies flying separately and in a multi-stage cascaded sequence. The method enables apparatuses for electricity harvesting from the fluid heat-energy, providing a positive net-efficiency. The method enables generators for practical-expedient power harvesting using constructive interference of waves due to the waving jet-effect.

Various aspects of this patent document relate to the rapid purification of cannabinoids by vaporization and condensation.

Methods and apparatus for processing hydrocarbon and other feedstocks that contain lighter volatile component(s) along with heavier volatile or non-volatile component(s) and/or contaminant(s). The principal benefit being that a feedstock can be processed and separated into its distinct volatile components down to elemental and/or molecular levels, including the ability to handle the heaviest tars and bitumen within the system. This effectively provides onsite value add to the feedstock resource (minus the waste streams such as water, sulfur, or sand; which may have value as isolated components in their own right). The system is robust and can include innovative hardware, methods, and/or software. The system can isolate water, chemical, various hydrocarbon, and particle contaminants of arbitrary concentrations and sizes. These factors provide for significant increases in processing efficiencies and capabilities in the fields of refining and environmental recovery. In a variety of operating scenarios, near-zero emissions can be achieved while processing.

A method of extracting an essential oil from plant matter, starting with providing plant matter to an interior of an extraction vessel, wherein the plant matter includes at least one essential oil. Next, at least one vacuum pump is used to reduce the pressure within the interior of the extraction vessel with the plant matter therein to an absolute pressure of less than 1.0 mm Hg absolute pressure. Microwave energy is applied to the plant matter while the interior of the extraction vessel is under the reduced pressure, thereby forming a vapor including at least a portion of the essential oil. The vapor is directed from the extraction vessel to at least one condenser vessel. Finally, the vapor is condensed to a liquid state such that the vapor includes at least a portion of the essential oil, by utilizing the at least one condenser vessel.

A novel solar-powered desalination and water purification system is disclosed herein. The system includes a nanofiber-impregnated graphene aerogel, an untreated water source, a water collection surface, and a purified water storage container. A novel photocatalytic nanofiber-impregnated graphene aerogel for desalination and photodegradation of contaminants for use in the disclosed system is also disclosed herein.
