The present disclosure relates to isolating one or more cannabinoids from an input mixture. There is disclosed an apparatus that comprises a volatizing unit, a fractional distillation unit, and a condensing unit. The volatizing unit receives and volatilizes the input mixture to provide a cannabinoid-containing vapor stream and a residue. The fractional distillation unit comprises a plenum for receiving the cannabinoid-containing vapor stream and separates a first cannabinoid from at least a second cannabinoid. The condensing unit is configured to receive a portion of the cannabinoid-containing vapor stream comprising the first cannabinoid from the plenum and to form a condensed first cannabinoid output stream and a recirculate stream. There are also disclosed methods for isolating one or more cannabinoids employing a recirculate stream.

According to an example aspect of the present invention, there is provided a method of removing volatile compounds from a lignin-containing material, the method comprising: providing a material comprising lignin and volatile compounds; treating the material by a distillation method in order to vaporize at least a part of the volatile compounds.

The components of the system are work conjointly to produce and process fresh water.

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.

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 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. The nanofiber-impregnated graphene aerogel exhibits excellent hydrophilicity, thermal insulation, and photodegradation capability, and allows for efficient solar-powered evaporation of water. The introduction of photocatalytic nanofibers into the graphene aerogel allows effective interfacial evaporation and in situ photodegradation of contaminants. The rate of water evaporation is preferably greater than 1.3 gal/ft.sup.2 per day, and the contaminant removal is preferably greater than 90%. A method of desalinating and purifying water using the disclosed system is also disclosed herein.

A process for recovering by-products of a substituted aromatic hydrocarbon oxidation reaction, comprising cooling one or more of a vapor stream directed to a high-pressure absorber (380), a solvent-rich scrubbing stream (381) directed to a high-pressure absorber (380), and a water-rich liquid stream (383) directed to a solvent recovery zone, by heat exchange with a cooled spent scrubbing liquid withdrawn from a low-pressure scrubber (430).

System, apparatuses, and methods for processing feedstock have a decomposing stage for breaking down feedstock into liquid and gaseous products and a condensing stage for condensing gaseous products to a liquid condensate. A mixing stage can also be used to combine gaseous and liquid feedstock portions into a combined liquid feedstock to be fed to the decomposing stage. The decomposing stage can be one or more flux tanks having a field generator for creating an electromagnetic field through the flux tank configured to decompose feedstock inside. The condensing stage can have a catalyst tank, distillation tank, condensing pipes, or a combination thereof. The mixing stage can be a reformer device having pairs of plates, at least some of the plates are capable of rotating to generate a shear force that creates a cavitation effect to combine the gaseous and liquid feedstock portions.
