Method and systems are disclosed for selectively removing naturally-occurring sugars in beverages in an effective, affordable and scalable manner.

A method of treating contaminated materials such as oil and gas production waste sludges to recover crude oil hydrocarbons. The method includes the inversion of water-in-oil emulsions, and subsequent separation steps. These may involve the separation and removal of asphaltenes, petroleum waxes and/or solid particles from the crude oil hydrocarbons. The treatment method uses the physical phenomena of hydrodynamic cavitation and hydraulic shock, which produce different effects upon a mixture of water and the contaminated material being treated. These are deployed either as single or combined stage(s) of treatment or as a repeated series of single/combined treatment stages, with or without additional processing operations between each single/combined treatment stage. The method may be implemented with suitable plant including hydrodynamic cavitation units (103, 106) and hydraulic shock units (104, 107), followed by separators (105, 108).

In one aspect, provided is a method for producing a semiconducting single-walled carbon nanotube dispersion. This method allows semiconducting single-walled carbon nanotubes to be separated from a single-walled carbon nanotube mixture containing semiconducting single-walled carbon nanotubes and metallic single-walled carbon nanotubes in an aqueous medium, and yet requires only an easily available separation agent and a simple operation.

One aspect of the present disclosure relates to a method for producing a semiconducting single-walled carbon nanotube dispersion. The method includes (A) preparing a single-walled carbon nanotube dispersion to be separated that contains single-walled carbon nanotubes composed of semiconducting single-walled carbon nanotubes and metallic single-walled carbon nanotubes, an aqueous medium, and a copolymer containing a constitutional unit A derived from a monomer represented by the following formula (1) and a constitutional unit B derived from a monomer represented by the following formula (3), and (B) centrifuging the single-walled carbon nanotube dispersion to be separated and then collecting a supernatant containing the semiconducting single-walled carbon nanotubes from the centrifuged single-walled carbon nanotube dispersion.

A system for collecting and separating biological material includes a centrifuge tube, a separation tube having an open bottom, a cap, a plug for temporarily sealing the open bottom of the separation tube, and a separation medium disposable within the centrifuge tube. The centrifuge tube and the separation tube sealingly and releasably couple to the cap, such that, when coupled, the separation tube is positioned within the centrifuge tube. The cap is configured to facilitate and/or regulate the introduction of air, gas, or other matter into the separation tube. When fully sealed, the separation tube may be placed under a vacuum condition, whereby a needle apparatus is used to facilitate introduction of matter into the separation tube. When the separation tube is positioned within the centrifuge tube, the bottom portion of the separation tube is submersed in the separation medium.

A method for producing an aligned boron nitride nanotube film includes drying a dispersion containing boron nitride nanotubes, a biopolymer, and a solvent.

A food processing system includes at least one receptacle containing a composition of water and insoluble solids, a centripetal force-based solid/liquid separator having an inlet, a solids outlet, and a liquid outlet, and a pump able to direct the composition from the receptacle to the inlet of the separator. The separator is configured to separate the composition into a solids stream including the insoluble solids and a liquid stream including water and to direct the solids stream through the solids outlet and the liquid stream through the liquid outlet.

A method and system are disclosed for producing a protein and fiber feed product from a whole stillage byproduct produced in a corn dry milling process for making alcohol, such as ethanol, and/or other biofuels/biochemicals. In one embodiment, the method includes separating the whole stillage byproduct into an insoluble solids portion and a centrate (solubles) portion. Thereafter, a fine fiber and protein portion may be separated from the centrate (solubles) portion. The fine fiber and protein portion may be dewatered to provide a protein and fiber feed product. In one example, the protein and fiber feed product can include insoluble solids, such as wet or dry distiller's grains with or without solubles. The resulting protein and fiber feed product may be sold and/or used as rumen feed, swine feed, chicken feed, aqua feed, food uses, or have other uses, including pharmaceutical and/or chemical usage, for example.

The present invention discloses a preparation process of food-grade potassium dihydrogen phosphate, wherein phosphoric acid prepared from wet-process phosphoric acid is used for the preparation of high-purity potassium dihydrogen phosphate. The preparation process of food-grade potassium dihydrogen phosphate provided in the present invention effectively reduces the preparation cost of the high-purity potassium dihydrogen phosphate and has the advantage of high process controllability, and by such a process, high-purity potassium dihydrogen phosphate crystals that meet the food-grade requirements can be produced, which crystals have uniform particle size distribution and comprises few fine powder, having a very high market value.

A bio emulsion fuel manufacturing apparatus and method using vegetable oil is provided, including an oil tank unit configured to refine a vegetable oil introduced from an oil inlet by using a coagulant agent and a centrifugal decanter; a water tank unit configured to pretreat a water introduced from a water inlet by using a water tank catalyst; a first HHO gas infuser unit configured to introduce nano-bubbles into the water inside the water tank; a mixed oil unit connected to the oil tank unit and the water tank unit, and configured to produce a mixed oil by using an inline mixer; an ionization catalyst unit connected to the mixed oil unit and configured to convert the mixed oil to a bio emulsion fuel by using an ionization catalyst group; and a second HHO gas infuser unit configured to introduce HHO gas into the bio emulsion fuel.
