A liquid process assembly, the assembly including a length of pipework, and a reversible pump for selectively reciprocally moving liquid through the pipework.

A process for extracting a target compound from a biomass includes: extracting a compound from a biomass charge using supercritical or subcritical CO.sub.2 as a solvent, at a first pressure and a first temperature, to yield a compound-laden solvent stream, the compound-laden solvent stream including the solvent, a solubilized target compound, and a solubilized byproduct compound; changing the temperature while maintaining the first pressure of the compound-laden solvent stream to desolubilize the byproduct compound from the compound-laden solvent stream to yield a resultant stream containing the solvent, the solubilized target compound, and a desolubilized byproduct compound; passing the resultant stream through a filter medium to separate the desolubilized byproduct compound from the solubilized target compound; and collecting the solubilized target compound.

The present disclosure provides a system for refining long chain dicarboxylic acid, comprising: a first membrane filtration unit, for a first membrane filtration of a long chain dicarboxylic acid fermentation broth or a treated liquid therefrom; a first decolorization unit, for carrying out a first decolorization treatment to the filtrate obtained after the membrane filtration; a first acidification/crystallization unit, for carrying out a first acidification/crystallization of a filtrate obtained after the membrane filtration to give a solid-liquid mixture; a first separation unit, for a solid-liquid separation of the solid-liquid mixture; a drying unit, for drying the solid separated by the separation unit to give a first solid. By using the refining system according to the present disclosure, the purity of the obtained product is high, and the disadvantages such as poor quality of the product obtained by crystallization from a solvent and environment pollution caused by a solvent can be overcome.

An ultrasound crystallization device includes a tubular crystallization reactor (102) for conducting process fluid containing substance to be crystallized, an ultrasound source (104) for radiating ultrasound to the tubular crystallization reactor, and a temperature-control structure (105) for controlling the temperature of the process fluid with the aid of temperature-control fluid. The tubular crystallization reactor is shaped to conduct the process fluid to flow around the ultrasound source, and the temperature-control structure comprises a flow-guide structure (106) for guiding at least a part of the temperature-control fluid to flow around the ultrasound source. The flow-guide structure improves the accuracy of the temperature control of the process fluid and also the ability of the temperature control to react to changes.

Various aspects of this patent document relate to liquid compositions comprising cannabidiol, which have either freezing points or glass-liquid transition temperatures less than the melting point of pure cannabidiol.

The present invention relates to a process for removing dissolved silica from a high pH brine produced by an evaporator employed in treating a waste stream. The high pH brine is directed to a crystallizer reactor and an acid or CO.sub.2 is mixed therewith to reduce the pH of the brine, causing the silica in the brine to precipitate. The brine is then directed to a first solids-liquid separator which produces a slurry containing the precipitated silica. The slurry is split into first and second streams with one stream recycled to the crystallizer reactor while the other slurry stream is directed to a second solids-liquid separator which produces a wet cake containing the silica solids.

Continuous extraction concentration and isolation units are constructed with at least one extraction chambers containing extractable material. Without disruption of total fluid flow in the unit: an extraction chamber completely depleted of extract can be refilled with fresh extractable material or can be replaced with an extraction chamber containing fresh extractable material. Extract are continuously separated from one or more solvents in expansion chambers and removed. All solvents can be retained within the unit. One or more compressors circulate the fluids through the extraction chambers, the expansion chamber, and a condenser, where the expansion chamber and the condenser can be coupled as a heat exchanger. One or more isolators can be included for selectively removing components that are extracted from the plant material without disruption of the process and provide the removed components in concentrated or pure form.
