A continuous vacuum fractionation system for separation of one or more of the plurality of components present in a raw cannabis extract into at least an overhead fraction, a bottoms fraction, and a side stream fraction, wherein the raw cannabis extract may be prepared by any of a variety of extraction techniques. The system includes an extract supply assembly having a primary feed pump, and one or more continuous fractionation units each including a modular fractionation column. Each column has a re-boiler, a close-coupled overhead condenser, and at least one modular fractionation stage, and further, the columns are operable in either series or parallel configurations. The close-coupled overhead condenser has an oversized impingement plate overlying a condenser inlet to minimize non-vapor components from entering and contacting the condenser. A vacuum assembly is provided to maintain at least the modular fractionation columns under a predetermined vacuum during operation.

A method for producing hemp oil, comprising decarboxylation of CBDA in hemp oil; short-path evaporation of CBD from the decarboxylated hemp oil to produce CBD oil; selective THC to CBN conversion performed on the decarboxylated hemp oil.

The present disclosure provides an apparatus and method for producing a policosanol having a specific chromatographic fingerprint. The apparatus of the present disclosure has a feed tank and receiving tanks which are connected to a vacuum system. The method of the present disclosure is carried out by a high vacuum rectification process and includes: firstly, feeding a saponified crude alkanol into a melting tank in which the material is melted and then flows into the feed tank, and then injecting the material into a rectifying still using a delivery pump, followed by first rectification under vacuum condition and sequential collection of fractions at different phases from the tower top and stillage residue from the tower bottom; and after the completion of the rectification of the first batch crude product, carrying out second feeding on the basis of consistent vacuum in the feed tank and the rectifying tower.

The process of producing concentrated maple sap can include concentrating the maple sap using membrane filtration to a sugar content of approximately 30° Brix, circulating the maple through a maple sap passage of a membrane, wherein the membrane contains the maple sap in a vacuum cavity, and evaporating the water from the maple sap across the membrane into the cavity. The concentrated maple sap having a sugar content above 50° Brix.

Also provided is a cleaning apparatus, without the distillator, the cleaning apparatus having a cleaning tank, a recirculating fluid tank located below the cleaning tank, a removable separator panel partitioning the recirculating fluid tank from the cleaning tank, and a fluid dispenser.

Process for recovering at least one fractional substance from vapours during the alcohol reduction of a beverage, and fractional substance recovery device for carrying out the process, in which an alcoholic beverage to be reduced in alcohol content is supplied to a degasser of a fractional substance recovery device, in which vapours are removed from the degasser and the alcoholic beverage passed through the degasser is supplied to a device for alcohol reduction, in which the vapours are fed to a plurality of fractional condensation stages which follow one another in series and in which at least one fractional substance is separated from the vapours under pressure and/or temperature, and in which the fractional substances separated in the respective fractional condensation stage are collected in a collecting container or are fed to an inoculation station, through which the separated fractional substances are fed in metered quantities to an alcohol-reduced drink.

A method for removing one or more congeners from an alcoholic composition, including placing a quantity of an alcoholic composition in a pressure-controllable environment, decreasing the pressure of the pressure-controllable environment, removing one or more unwanted congeners from the alcoholic composition to yield a purified alcoholic composition, and removing the purified alcoholic composition from the pressure-controllable environment.

We disclose a process for purification of mixed hydrocarbons, suitable for a wide range of contexts such as separating and recovering mixed polymer materials, refining used oils and fuels, recovery of hydrocarbons from used tyres, recovery of hydrocarbons from thermoplastics etc, to yield clean hydrocarbon distillates suitable for use as recycled feedstocks in chemical industries or as low sulphur fuels for motive use, as well as the treatment of crude oils, shale oils, and the tailings remaining after fractionation and like processes. The method comprises the steps of heating the hydrocarbon bearing material thereby to release a gas phase, contacting the gas with an aqueous persulphate electrolyte within a reaction chamber, and condensing the gas to a liquid or a liquid/gas mixture and removing its aqueous component. It also comprises subjecting the reaction product to an electrical field generated by at least two opposing electrode plates between which the reaction product flows; this electrolytic step regenerates the persulphate electrolyte which can be recirculated within the process. The process is ideally applied in an environment at lower than atmospheric pressure, such as less than 14000 Pa. A wide range of mixed materials and hydrocarbons can be separated and treated in this way. Used hydrocarbons such as mixed plastic packaging waste, industrial polymers, pyrolysis oils etc, are typical examples, but there are a wide range of other materials having a hydrocarbon content. One such prime example is a mix of used rubber (such as end-of-life tyres) and used oils (such as engine oils, waste marine oils) etc, which can be pyrolysed together to yield a hydrocarbon liquid which can be treated as above to provide a carbon black residue that has extensive industrial uses.

A system for processing cannabinoids and recovering solvent has a vessel for a mixture of cannabinoids and solvent. A pump forms a vacuum in the system to draw the mixture into a first heat exchanger to pre-heat the mixture. A falling film evaporator receives the mixture from the first heat exchanger, and boils the mixture to form a solvent vapor. The falling film evaporator collects the cannabinoids from the mixture as a crude oil. The first heat exchanger receives the solvent vapor. Heat is transferred to incoming mixture of the system, and cools and condenses the solvent vapor to form solvent condensate and vapor. A second heat exchanger receives and further cools the solvent condensate and vapor to form further condensed solvent and some solvent vapor. The pump receives the further condensed solvent and some solvent vapor and increases pressure to form solvent liquid and recovers solvent liquid for reuse.
