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.

A powdered, water-soluble Full Spectrum Hemp Oil is formed using organic materials and natural products to form a non-GMO, fast acting, whole plant hemp extract without harsh chemicals such as hexane. The Full Spectrum Hemp Oil may be extracted using CO2 concurrent gas extraction to avoid use of chemical additives.

Disclosed is a spreadable propolis products which can be used in many sectors such as food, health and cosmetics that offer them for human consumption in their most suitable and in the highest form of bioavailability, in a fast and easy consumable state by properly extracting propolis which cause development of antioxidant, antimicrobial, antifungal, antivirus, anti-inflammatory, anti-cancerogen and anesthesic effects as well as many beneficial biological activities. Production methods thereof are also disclosed.

A rotary evaporator for evaporating a substance contained in an initial substance comprises an evaporation flask (2) for receiving the initial substance, a device (3) for heating the substance, a condenser (4) for condensing the vaporized substance, a collection container (6) for receiving the re-liquefied substance and at least one device (5) for generating a low pressure and/or an excess pressure. In order to remove the re-liquefied substance an excess pressure can be generated at least within the collection container (6) and/or in order to remove residues of the initial substance an excess pressure can be generated at least within the evaporation flask (2).

An evaporative system for separating solid salt from a saline solution is provided. The system comprises conveyor belts arranged to move the saline solution and evaporate water from it, using natural solar radiation, reflected solar radiation, mechanically induced evaporation and heat storing materials, which accumulate heat during the day and release the heat during the night to allow continuous production. The system may be adapted to different saline solution sources and terrain conditions as well as to varying meteorological conditions. The conveyor belts may be interspaced by separators that remove from the saline solution each type of salt as it solidifies on the corresponding conveyor belt. Conveyor belts may further be used to deliver the solid salt or wastes back to saline solution source.

A process for producing THC-O-acetate using a succession of distillation, salting-out assisted liquid-liquid extractions (SALLEs), and solvent recovery techniques. Tetrahydrocannabinol (THC) in cannabis oil reacts with acetic anhydride under reflux to produce THC-O-acetate and acetic acid. The resulting crude product is distilled and subjected to a SALLE with hexane followed by a SALLE with petroleum ether, before being distilled again in order to obtain a refined, THC-O-acetate product.

A process of converting cannabidiol (CBD) to Δ.sup.8-tetrahydrocannabinol (Δ.sup.8-THC) or Δ.sup.9-tetrahydrocannabinol (Δ.sup.9-THC) can enable mass production of Δ.sup.8-THC and/or Δ.sup.9-THC, achieve greater yields and higher purity in comparison to previously reported processes while eliminating the use of organic solvent. The resultant hemp-derived Δ.sup.8-THC can be mixed with and absorbed by natural extracts, including tea extract, starch, sugar, lecithin, and other emulsifiers. Δ.sup.8-THC used in edible, topical and vaping products such as powdered Δ.sup.8-THC food ingredients, tablets or pills, suppositories, and vape formulations are disclosed. Further described are beverages and baked goods utilizing or incorporating the tablets or powdered Δ.sup.8-THC to create edible products containing an emulsified, tasteless, and odorless dose of Δ.sup.8-THC. The disclosure also describes a rectal suppository designed to provide improved comfort of use. A Δ.sup.8-THC liquid composition can be use in an electronic cigarette smoking device for pulmonary administration of Δ.sup.8-THC, which results in more effective absorption.

The invention relates to the field of olefin oligomerization to obtain liner α-olefins, particularly to a method of separating olefin oligomerization products using an evaporator. The invention includes two embodiments of the method of separating the oligomerization reaction product streams. In accordance with the first embodiment of the invention, the oligomerization reaction product stream after the step of isolating an initial olefin is fed into an evaporator to the step of separating the oligomerization reaction product steam. In accordance with the second embodiment of the invention, the oligomerization reaction product stream after the step of isolating the initial olefin is separated into two streams, the first part of which is fed into the separation column, and the second part is fed into the evaporator. The invention allows to minimize a quantity of technological equipment contaminated by the by-product polymer.

A Brayton cycle adsorption desalination system includes an adsorption desalination system including an evaporator for evaporating saline water to obtain water vapor, an adsorbent bed for adsorbing and desorbing the water vapor, and a condenser for condensing the water vapor to obtain distilled water. The Brayton cycle adsorption desalination system further includes a Brayton cycle system including a primary heat exchanger (PHE) and a cooler configured to cool an exhaust from the PHE. The Brayton cycle system and the adsorption desalination system are connected at the PHE so that the PHE is configured to function as a heat source for the adsorbent bed. The Brayton cycle system and the adsorption desalination system are connected at the cooler so that the evaporator is configured to absorb heat rejected from the cooler.

A distillation apparatus includes an evaporator-condenser heat exchanger in combination with a compressor. The heat exchanger is mounted to float in an at least partially immersed position in a sump of liquid. The liquid may be a sap, or may be soiled water, and may have suspended solid. Heating of the liquid yield steam, the steam is compressed, and the heated, compressed steam is fed back into the heat exchanger to provide further heat to the liquid. The process yields a concentrated in the liquid bath and distilled water, each of which may be a desired product. The system may include a pre-heater that exchanges residual heat from the hot distillate with the cooler input liquid. The apparatus and process may have multiple stages.
